Covid Patients Are 40% More Likely to Get Diabetes – What Does That Mean for Your Vision?

Covid 19 Patient Sick in BedHave you had Covid-19? After your fever and cough have subsided, you may think the virus is behind you. However, even after your Covid test comes back negative, you may experience health problems in the near future, including diabetes.

Recent studies have found that a significant percentage of post-Covid-19 patients developed diabetes within a year of contracting the virus. This is particularly problematic, as diabetes raises the risk of developing many health problems, including several sight-threatening eye conditions that can rob people of their vision.

What Does the Research Show?

A March 2022 Lancet study that evaluated the records of 181,280 U.S. military veterans found a 40% higher risk of developing Type-2 diabetes in those who had Covid. Although those at greatest risk were over 65, African American and/or had underlying health conditions, many younger patients also developed Type 2 diabetes.

A study published in January 2022 by the Centers for Disease Control (CDC) found that children and teens under 18 were more likely to receive a new diabetes diagnosis (both Type 1 and Type 2) at least 30 days after infection than those who never contracted Covid.

Scientists are investigating exactly why Covid-19 raises the risk of developing diabetes. In many cases, it’s believed that the virus targets pancreatic cells, which are responsible for making insulin, a hormone that regulates blood sugar levels. A lack of insulin causes diabetes.

Some scientists also theorize that inactivity and weight gain due to lockdowns and quarantines may have raised the risk of developing diabetes.

Diabetes-Related Conditions

Diabetes is linked to many eye conditions, including:

Blurry Vision – High blood sugar drives the lens inside your eye to swell, causing your vision to blur.

Cataracts – Diabetes can cause cataracts, cloudy patches that form in the lens of the eye.

Glaucoma – This disease develops from high pressure inside the eye and can lead to severe vision loss.

Diabetic Retinopathy – High blood sugar levels damage the small fragile blood vessels on the retina, leading to vision loss.

Maculopathy – Swelling of the macula, the center of the retina, can make it difficult to drive, read or see detail.

Some of these conditions have no noticeable symptoms during their early stages when it’s still possible to prevent or minimize vision loss. So having regular comprehensive eye exams is crucial.

How to Reduce Your Risk of Diabetes Post-Covid

Even after you’ve recovered from Covid, you may still be at a higher risk of developing diabetes. So, along with people who have a family history of the disease, make sure to book a comprehensive eye exam, eat a healthy and balanced diet, don’t smoke, maintain your appropriate weight, and ask your physician to monitor your blood sugar levels.

Also, if you have any eye symptoms, such as blurry vision, schedule an appointment with immediately. Remaining vigilant and aware of the risks can help safeguard your vision thanks to early intervention and treatment.

Q&A with Dr. Ben Giddens

Q: What is a diabetic retinal eye exam?

A: A diabetic retinal [eye__exam] checks for diabetic retinopathy, a condition that affects the small thin blood vessels in the retina located at the back of the eye. Your optometrist will place eye drops into your eye to open your pupils so they can more easily see the back of your eye. They may take digital images to inspect blood vessels: these full-color 3D images show the cross-section of the retina and measure the retinal thickness to help your optometrist detect any fluid or blood leakage.

Q: How common is vision loss with diabetes?

A: People with diabetes are more likely to experience eye and vision problems. Among people over 45 diagnosed with diabetes, 17.6% experience some degree of vision loss.
– 9.2% is caused by cataracts
– 4.1% is caused by diabetic retinopathy
– 2.2% is caused by macular degeneration
– 2.1% is caused by glaucoma. Therefore, anyone diagnosed with or with risk factors for diabetes should have regular eye exams to protect their vision and eye health.

5 Need-to-Know Facts About Glaucoma

elderly couple sitting outside width=While most people have heard of glaucoma, many aren’t aware of how and why it can lead to vision loss and blindness, and why or how regular eye exams can help safeguard their vision. To get a better understanding, check out these 5 important facts.

Glaucoma Causes Permanent Vision Loss

Glaucoma is a leading cause of vision loss and blindness, affecting more than 1 in 50 adults. Nowadays, more than 80 million people around the world have glaucoma, with the number is expected to reach a staggering 111 million by 2040!

Vision loss is caused by abnormally high pressure within the eye which permanently damages the optic nerve that delivers the eye’s messages to the brain.

The rise in eye pressure results from the buildup of fluid in the eye that does not drain effectively out of the eye.

Though it’s possible to manage glaucoma symptoms, vision loss can’t be reversed once it’s occurred. That’s why it’s crucial to catch this serious eye condition in its early stages.

Half the People With Glaucoma Don’t Know They Have It

Yes, you read that correctly. One of the most worrying things about glaucoma is that half the people with this condition don’t even know they have it! The most common type — primary open-angle glaucoma — has no obvious symptoms in its early stages. It’s no wonder glaucoma is called the ‘Thief of Sight.’

The best way to avoid any vision loss from glaucoma is to have regular eye exams to detect the condition as soon as possible.

Some Are More At Risk for Glaucoma Than Others

The following are risk factors for glaucoma:

  • Being 60 or older
  • A family history – particularly of open-angle glaucoma
  • African, Asian or Hispanic descent
  • High blood pressure
  • Diabetes
  • Underactive Thyroid

Glaucoma Can Be Treated, Not Cured

There is no cure for glaucoma and vision that has already been lost to the condition can’t be restored. However, glaucoma can be treated, and the progression of the disease can be stopped or slowed.

Common treatments for glaucoma include:

  • Prescription eye drops that can lower pressure inside the eye
  • Oral medications, such as carbonic anhydrase inhibitors
  • Laser therapy, such as SLT or trabeculoplasty, is used to open up channels to improve the drainage of fluid from the eye
  • Eye surgery or trabeculectomy – surgical removal of obstructions in the eye’s drainage system
  • Trabecular stent bypass – a stent is placed in the eye to make drainage easier

Only an Eye Exam Can Diagnose Glaucoma

As mentioned above, regular eye exams are essential to detect glaucoma, especially in the early stages before permanent vision loss has occurred. Your eye doctor may use several types of tests to detect glaucoma:

  • Tonometry – measurement of eye pressure
  • Visual field – tests for peripheral vision loss
  • Gonioscopy – determines if the drainage system is open.
  • Corneal thickness (pachymetry) – the thickness of the cornea can affect the eye pressure measurements
  • Optic Nerve Exam – detection of any nerve damage using digital imaging

Glaucoma is yet another good reason to get your eyes tested regularly, especially if you’re over 60. To check the health of your eyes, schedule a comprehensive eye exam at today.

Frequently Asked Questions with Dr. Ben Giddens

Q: How much time does it take for glaucoma to cause blindness?

  • A: In most cases of open-angle glaucoma, it can take several years from the onset of the disease before significant vision loss occurs. However, in the case of closed-angle glaucoma, where the eye pressure rises suddenly, it can immediately cause severe vision loss. The speed of the onset of glaucoma depends on the type of glaucoma and eye pressure levels. The higher the pressure, the faster glaucoma can drive vision loss.

Q: How many people go blind from glaucoma?

  • A: Overall, the incidence of blindness in at least one eye from glaucoma is 26.5% after 10 years, and 38.1% after 20 years. This means that without effective treatment the chance of going blind in one eye is more than 1 in 4 in just 10 years.

Signs It’s Time For Cataract Surgery

Elderly Couple Discussing Cataract SurgeryCataract surgery, which replaces the cataract-affected lens of the eye with a new, clear artificial lens, is the most common surgical procedure in the world. While the procedure is considered safe and effective, patients want to know the optimal time to have the surgery.

Early Signs of Cataracts

During the earlier stages, individuals with cataracts experience cloudy vision and sensitivity to glare and light. Halos may appear around lit objects at night, and night vision may be impaired. Colors may appear washed out, such as bright red hues appearing dark pink.

Signs You Need Cataract Surgery

It’s common for people to live with cataracts for several years before considering surgery. The following are signs it is time to have your cataracts removed:

  • You find it difficult to see well enough to perform tasks at work
  • Your vision has gotten in the way of doing activities around the home, such as cooking and cleaning
  • You no longer see the television screen or printed material clearly
  • Driving, especially at night, no longer feels safe
  • Glare and bright lights are more pronounced

If you experience any of the above, schedule an appointment with your eye doctor to discuss cataract surgery.

The Presence of Other Eye Problems

Your eye doctor may encourage you to have cataract surgery if your cataracts render it difficult to examine the back of your eye to treat a range of serious eye conditions, such as glaucoma, macular degeneration and retinopathy. Any of these may require the urgent removal of the cataract so the optometrist can accurately diagnose and manage other serious eye problems.

What Happens If You Delay Surgery?

There are advantages to having cataract surgery earlier rather than later. Cataracts can severely interfere with daily life and can make night driving difficult, even hazardous. If left untreated, cataracts result in vision loss and eventually blindness. Additionally, over time cataracts become thicker, darker and denser, which can add unnecessary complications to the surgery and lengthen the post-surgery recovery period.

However, in certain cases, patients can wait to have cataract surgery. In the meantime, their eye doctor can recommend stronger prescription lenses or the use of bright lights to help them see better.

Whether you decide to get cataract surgery early on or to wait it out, we encourage you to do so under the guidance of at .

6 Glaucoma Myths Debunked

elderly couple with their familyGlaucoma can do a great deal of damage to your visual system if it goes undetected and untreated. Unfortunately, there is a lot of misinformation out there about glaucoma symptoms, detection and treatment that cause people to wait to see an eye doctor until it’s too late to prevent vision loss. In this article, we debunk 6 common glaucoma myths.

Myth 1: Glaucoma testing is painful

The Truth: Glaucoma testing is basically painless.

The most commonly used first test for glaucoma is an air puff test. Your optometrist will ask you to place your chin on a chin rest and while looking at a small light, a quick, soft puff of air will be blown at your eye to test the pressure inside your eye. The test takes mere seconds and reveals a great deal of valuable information to your eye doctor about your risk of glaucoma.

Your optometrist may also use an OCT device to create a full-color 3D scan of the inside of your eye, and perform visual field testing to see if the eye pressure has caused any changes to your field of vision. Both these tests can detect damage to ocular structures caused by glaucoma. Both tests are completely non-invasive, as neither touch the eye.

If necessary, your eye doctor may use anesthetic eye drops as part of a Goldmann applanation tonometry test. While these drops may sting slightly for a few seconds, the rest of the test is completely painless. After the anesthetic is applied, your eye doctor will use a small probe and a blue light to quickly and gently touch the cornea. This is an additional method to accurately determine the exact measurement of your inner-eye pressure.

Myth 2: Glaucoma cannot be prevented

The Truth: There are many steps a person can take to minimize their risk of developing glaucoma. They include:

  • Living a healthy lifestyle.

Research published in March 2016 in JAMA Ophthalmology has shown that a healthy diet that includes a lot of fruits and vegetables (especially the green leafy kinds) significantly reduces a person’s chances of developing glaucoma. Regular exercise helps as well, with experts suggesting that a regular routine of moderate to vigorous exercise may reduce risk by as much as 73%. Ask your physician about an appropriate exercise regimen for your age and body type. If you smoke, quitting could significantly lower your risk of glaucoma.

  • Having regular comprehensive eye exams. This one is especially important if you have a history of glaucoma in your family since glaucoma can be hereditary. Even if you don’t have a family history, regularly scheduled eye exams are important. Early detection of risk factors associated with glaucoma can put your optometrist on the lookout for subtle warning signs.
  • Protecting your eyes from injury. Severe eye injuries can significantly raise your risk of glaucoma. [Eye_doctors] recommend wearing protective eyewear any time you take part in activities where foreign objects may get in your eyes. This includes woodworking, soldering or working with any kind of paints or chemicals. Many sports, including baseball and racquetball, have a high incidence of eye injury.

Myth 3: There’s only one type of glaucoma

The Truth: There are several types of glaucoma. Each has its own causes and treatments.

The two most common types of glaucoma are open-angle and angle-closure glaucoma.

With angle-closure glaucoma, the structure in your eye responsible for the healthy outflow of fluid from the eye, known as the trabecular meshwork, becomes blocked. This prevents the outflow of fluid from the eye, elevating the intraocular pressure, damaging the ocular nerve and leading to vision loss.

This increase in eye pressure and nerve damage can occur suddenly or gradually over time. If a sudden spike in pressure occurs, the symptoms may include severe headache, nausea, vomiting, eye pain and seeing halos around lights.

Open-angle glaucoma occurs when the trabecular meshwork remains open, but there is still resistance to the outflow of fluid from the eye. This resistance creates a slow build-up pressure inside the eye, and just as in angle-closure glaucoma, damages the optic nerve and leads to vision loss. Open-angle glaucoma develops slowly and shows no obvious symptoms until irreversible damage to your eyes and vision has occurred.

Myth 4: Once you have glaucoma, nothing can be done to help

The Truth: While it is true that there is no cure for glaucoma, optometrists do have a number of options to help lower intraocular pressure, reduce its impact and save your sight

Treatment usually starts with medicated eye drops and oral medications that either increase the outflow of fluid from the eye or decrease the amount of fluid your eye produces.

If these treatments don’t work, eye doctors may also recommend the surgical implantation of drainage tubes, laser therapy or minimally invasive glaucoma surgery.

Myth 5: Only older people get glaucoma

The Truth: It is true that people over 60 are at the highest risk for glaucoma. However, glaucoma can affect people at any age.

Even infants can develop glaucoma if they’re born with certain conditions or birth defects that affect the eyes.

Individuals who are more susceptible include:

  • People who have sustained a serious eye injury in the past
  • People with a family history of glaucoma
  • Diabetics and those suffering from conditions such as cardiovascular disease and sickle-cell anemia
  • Those taking steroid medications long-term
  • African Americans and Hispanics
  • Asians (have a higher risk of closed-angle glaucoma)

Myth 6: You can’t have glaucoma if you don’t have symptoms

The Truth: Open-angle glaucoma is the most common type of glaucoma, accounting for over 90% of all glaucoma cases. Unfortunately, this type of glaucoma shows no noticeable signs or symptoms until vision loss has occurred.

Since glaucoma tends to impact the peripheral (side) vision first, many people might not notice that their vision is gradually shrinking. This is why regular comprehensive eye exams are so important to ensure that glaucoma is caught early, and a treatment plan can be devised well before serious damage has occurred.

Glaucoma can be a devastating eye condition if not caught and treated as early as possible. To find out more about prevention and treatment of glaucoma and similar eye conditions, contact us today.

 

Frequently Asked Questions with Dr. Ben Giddens

Q: Can smoking harm my eye health?

  • A: Yes. In multiple studies, researchers have found that the more cigarettes a person smokes each day, the higher their risks of developing glaucoma. Beyond glaucoma, smokers are also at a significantly higher risk of developing other eye diseases, including cataracts, age-related macular degeneration, diabetic retinopathy and dry eye syndrome.

Q: When should I consider glaucoma surgery?

  • A: Glaucoma surgery should be considered if your eye doctor has tried all other treatments, including prescription eye drops, oral medications and laser therapy, without success. Many types of glaucoma surgery exist. Ask your eye doctor to assess your condition and help decide which surgery is the best option to reduce your risk of vision loss, including blindness.Surgery cannot restore vision already lost because of glaucoma, but it can help protect the vision you still have and prevent your glaucoma from worsening.

What’s a Multifocal Intraocular Lens?

Elderly Lady with Multifocal Intraocular LensesA cataract clouds the eye’s natural lens, leading to significant visual distortions that can affect your ability to see clearly. Eventually, the natural lens will need to be removed and replaced with an artificial intraocular lens (IOL) that provides clear vision.

While most patients pick monofocal IOLs, many patients choose multifocal IOL lenses. Discuss with your [eye_ doctor] which type of IOL is right for you.

What Is a Multifocal Intraocular Lens?

A multifocal IOL allows patients to see all distances clearly. These IOLs allocate different optical powers on the IOL. The varying optical powers are created by the IOL design, which incorporates concentric rings on the surface of the lens. These allow images at a variety of distances to be in sharp focus.

It can take some time for people to adapt to multifocal IOL lenses because the focusing power the lenses provide is different from what people are accustomed to. Since the IOL relies on a different design than the bifocal or multifocal optical lenses used in eyeglasses, the brain might need time to adjust.

To ease the adjustment, most cataract surgeons recommend having multifocal IOLs implanted in both eyes, rather than just one.

Are Multifocal IOLs Right for You?

If you are looking for an IOL that can provide you with clear vision for reading, driving and watching TV, a multifocal IOL may be just right for you.

After cataract surgery, multifocal IOLs can reduce the need for reading glasses or computer glasses. These implanted lenses widen your field of vision, allowing you to see well both up close and far, often without the use of glasses. Many patients who choose multifocal IOLs find that they can go glasses-free or only occasionally need reading glasses for small print after surgery.

Despite the obvious benefits of these lenses, they may not be suitable for everyone. Some patients find that it takes longer to adapt to multifocal lenses than to monofocal lenses. Contact to discover whether IOL multifocal lenses are right for you.

Frequently Asked Questions with Dr. Ben Giddens

Q: How does a multifocal IOL work?

  • A: When wearing bifocal or multifocal glasses, you look through the bottom part of the lens for near vision and through the top part of the lens for distance vision. A multifocal IOL is specially designed to provide clear vision at all distances at all times. Your brain adjusts, allowing you to see clearly for the task at hand.

Q: Will a multifocal IOL eliminate the need for glasses?

  • A: Most people find they do not need glasses with multifocal IOLs, but some do, depending on the situation. There may be times when the print or graphics are simply too small or too far away to be seen without glasses. serves patients from Georgetown, Limehouse, Acton, and Halton Hills, Ontario and surrounding communities.

What Causes Retinal Tears?

Close up of an eyeThe retina is the light-sensitive tissue that lines the inner back portion of the eye. It is responsible for gathering incoming light and sending images to the brain.

A retinal tear is a small break in the inner lining of the retina. It can be caused by many factors and can occur at any age. Aging, eye trauma, eye surgery or severe myopia may all cause retinal tears or detachments. Left untreated, a retinal tear may lead to retinal detachment, a severe sight-threatening eye disease that can result in blindness.

What are the Symptoms of Retinal Tears?

Patients with retinal tears often experience one or more of the following symptoms:

  • Flashes of light
  • Sudden onset or increase of floaters
  • Seeing a shadow in your side vision
  • Blurred vision
  • Seeing a gray curtain moving across your visual field

In some cases, however, retinal tears may not produce any noticeable symptoms.

What Causes Retinal Tears?

The eye is filled with a substance called the vitreous, a gel-like consistency. At birth, the vitreous is attached to the retina, but as we age, the vitreous transforms into a liquid that slowly detaches from the retina in a process called posterior vitreous detachment (PVD).

Usually, this process occurs without any complications. If the vitreous detaches too suddenly or abnormally, it tugs on the retina and can tear it. Certain people have a more “sticky” vitreous, which makes it easier for the retina to rip.

Another leading cause of retinal tears is eye trauma. Blunt force eye trauma can cause the retina to become bruised or scarred, making it more vulnerable to tearing.

Other associated causes or risk factors of retinal tears include:

  • Diabetes
  • Personal or family history of retinal tears/detachment
  • Retinal degeneration
  • Inflammatory disorders
  • Certain cancers
  • Autoimmune disease
  • Severe myopia
  • Sickle cell disease
  • Retinopathy of prematurity
  • Prior eye surgery

Be sure to disclose any relevant medical information to your eye doctor for optimal eye care.

How are Retinal Tears Treated?

Retinal tears are typically treated surgically with a laser (photocoagulation) or cryotherapy. Both methods are considered very safe and effective.

These treatments reseal the retina to the back wall of the eye and prevent fluid leakage underneath the retina.

The prognosis of a retinal tear is very positive when caught early, making regular eye exams that include examination of the retina crucial for all adults.

In some cases of minor retinal tearing, no treatment is required. If the retinal tear causes no symptoms, close monitoring may be all that’s needed.

After Your Retinal Tear Has Been Treated

Following treatment, your optometrist will schedule various eye exams in order to monitor changes in your retinas or eye health. Inform your eye doctor immediately if you notice any changes in your vision or if you experience new symptoms that may signal a problem.

If you or a loved one has been diagnosed with a retinal tear or is at risk of developing one, it should be treated right away to avoid further vision problems. Call to schedule a consultation and discuss treatment options.

 

Frequently Asked Questions with Dr. Ben Giddens

 

Q: Does retinal detachment and glaucoma both cause vision loss?

  • A: Yes. Vision loss among those with glaucoma is caused by abnormally high pressure within the eye which permanently damages the optic nerve that delivers the eye’s messages to the brain.

Q: Is retinal detachment the same as diabetic retinopathy?

  • A: No. Though they both affect the retina and can lead to vision loss, they have different causes and affect the eye differently. Diabetic retinopathy occurs when the small blood vessels in the retina swell and leak as a result of high blood sugar levels. The new thin and fragile blood vessels that grow may bleed, causing scar tissue. Left untreated, diabetic retinopathy can result in permanent vision loss, even blindness.

What Is Excess Eye Fluid?

What Is Excess Eye Fluid 640×350Collagen, water and protein make up the majority of the human eye, and tears are always present to help keep the eye moist. However, surplus fluid can occasionally accumulate inside the eye and signal a serious eye problem.

Several factors may contribute to this problem.

There are two primary sources of fluid inside the eye. The first is needed to flush out waste products from behind the cornea, leading it to flow out from the eye through the anterior angle. The second type of fluid is found in blood vessels that nourish the retina and macula at the back of the eye.

Conditions that Cause Excess Eye Fluid

Several conditions can result in excess eye fluid, and each is managed and treated in its own way to prevent eye damage and vision loss. These conditions include:

Macular Degeneration

Macular degeneration is the deterioration of the central part of the retina, called the macula. Fluid build-up on the macula causes the wet form of macular degeneration, which affects central vision and the ability to see fine details. This usually occurs when very fragile new blood vessels form in the retina. These abnormal blood vessels leak fluid, made up of plasma and blood into the retina.

Glaucoma

Glaucoma develops when the eye’s drainage system becomes clogged, inhibiting the flow of fluid through the anterior angle and causing fluid to accumulate in the eye. Glaucoma can also develop when the eye produces more fluid than usual and is unable to drain it quickly enough. In both cases, as the fluid builds up inside the eye, the pressure inside the eye rises, potentially damaging the nerve fibers that send all our visual signals from the eye to the brain. The optic disc becomes hollow and cupped as a result of the injured nerves.

Glaucoma will progress if extra fluid continues to collect in the eye, and can lead to serious vision loss or blindness if left untreated.

Macular Edema

Macular edema occurs when there is a build-up of fluid in the macula. The macula is positioned in the middle of the retina, which is the neural tissue at the back of the eye that sends the light signals to the brain and allows you to see.

Damaged blood vessels in the retina cause fluid to accumulate in the macula. This leads to compromised vision, with common symptoms including blurred or wavy vision in the center of your field of vision.

Diabetic Macular Edema

Diabetic macular edema is a result of diabetic retinopathy. There are two types of diabetic retinopathy, based on the stage of the disease: nonproliferative retinopathy (when blood vessels in the retina enlarge and leak) and proliferative retinopathy (when abnormal new blood vessels form on the retina).

Blurred or double vision, as well as floating, dark patches in your vision, are all common symptoms of diabetic macular edema.

Central Serous Retinopathy

Central serous retinopathy occurs when fluid accumulates behind the retina. The fluid buildup is caused by leaking from the layer of blood vessels beneath the retina (choroid).

When the retinal pigment epithelium, the layer between the retina and the choroid, fails to function properly, fluid builds up behind the retina, causing the retina to detach and vision to be impaired. Symptoms include dimmed, distorted or blurred vision, as well as straight lines seeming crooked or bent.

Treatment for Excess Eye Fluid

Treatments often include reducing pressure produced by fluid buildup and treating the underlying cause of the buildup.

In diabetic macular edema, for example, your eye doctor will recommend treatment for your diabetes along with treatment for the retinal impairment that is causing fluid buildup.

In some circumstances, surgery may be required. For instance, glaucoma patients may require surgery to create a new opening from the eye through which fluid can drain. Certain medications can also assist in fluid drainage from the eye, which works to lower the pressure inside the eye or causes the eye to produce less fluid.

Intravitreal injection is a treatment used when there is a buildup of fluid in or under the retina. Anti-VEGF medications absorb fluid and stop fluid/blood from leaking out of blood vessels, which is a common occurrence in both macular edema and wet macular degeneration.

If you have signs of fluid buildup, it’s essential to promptly speak with your eye doctor. Treatment will be more successful once the underlying disease is identified.

Frequently Asked Questions with Dr. Ben Giddens

Q: What is wet macular degeneration?

  • A: Wet macular degeneration is an eye disease that causes blurred vision or a blind spot in your visual field. It is caused by abnormal blood vessels that leak fluid or blood into the macula, the section of the retina responsible for central vision. Symptoms like visual distortions and increased blurred vision tend to appear suddenly and quickly worsen.

Q: What other conditions can cause excess fluid in the eye?

  • A: Other conditions that may cause excess fluid in the eye include:
  • Choroidal effusion – the buildup of fluid between the choroid, the sclera, and a layer of blood vessels on top of the retina.
    A retinal tear – may cause fluid to accumulate and lead the retina to detach.
    Chemosis – a swelling of the eye due to accumulation of fluid often caused by allergies or eye infection.


Sugar, Diabetes & Glaucoma – What’s the Connection?

Sugar, Diabetes Glaucoma 640Diabetes is a disease caused by the body’s inability to use or produce insulin. Insulin is the hormone responsible for taking sugar out of the blood and placing it into cells, where it is used to create energy. When the body can’t use or produce sufficient insulin, it causes sugar levels to rise too high.

A common complication for people with diabetes is diabetic eye disease, a group of sight-threatening eye problems. Glaucoma is one of these diseases.

In fact, having diabetes doubles your risk of developing glaucoma

Glaucoma is one of the most common causes of blindness worldwide. It is caused by pressure build-up within the eye, which leads to permanent damage to the retina and the optic nerve.

If you have diabetes, it’s important to manage your condition in order to preserve your eyesight.

How Diabetes Affects Your Eyes

Diabetes affects your body’s ability to maintain normal blood sugar levels. If your blood sugar rises too high, it can place stress on major organs, including your eyes and kidneys.

The vast majority of glaucoma cases present no symptoms until irreversible vision loss has occurred. Fortunately, your eye doctor can detect sight-threatening eye diseases early on by examining the retina and optic nerve. Left untreated, glaucoma can seriously impair your vision, or leave you partially or completely blind.

Importance of an Eye Exam

To limit the impact of diabetes on your vision, schedule regular visits to your eye doctor. This will enable your eye doctor to assess your eyes and diagnose any diabetes-related vision problems as early as possible. This can improve your chances of preventing or slowing the progression of glaucoma significantly.

If you have diabetes and are concerned about potential risks to your vision, contact to schedule an appointment. We can help preserve your vision before it’s too late.

Q&A

Q: Is there a cure for glaucoma?

  • A: There is no cure for glaucoma. However, with early diagnosis and proper treatment, the risks of vision loss can be significantly reduced. That’s why routine comprehensive eye exams are so important.

Q: What glaucoma treatments are currently available?

  • A: Your eye doctor will most likely prescribe glaucoma eye drop medications that reduce intraocular pressure. If the eye drops don’t work, laser or eye surgery may be the next step. Depending on the advancement of your glaucoma, surgery might be the first option for glaucoma treatment.


How Eye Disease And Cataracts Affected The Work Of Famous Artists

For many art enthusiasts, analyzing the differences in color choices and techniques that an artist employed over the course of their career offers a window into the artist’s soul.

But to eye doctors, these changes in color and style offer a glimpse into the artist’s eye health.

When comparing the paintings from an artist’s youth to their older years, the changes suggest that eye disease may have affected their vision — and, consequently, their artwork.

Did Eye Conditions Affect the Work of Famous Artists?

Cataracts

Cataracts are a clouding of the eye’s crystalline lens and a natural part of the aging process. People with cataracts eventually develop blurred vision and perceive colors as faded or yellow-toned.

Claude Monet struggled with cataracts in his 60’s. Upon noticing that his eyesight was changing, he wrote the following to an eye doctor in Paris:

“I no longer perceived colors with the same intensity… I no longer painted light with the same accuracy. Reds appeared muddy to me, pinks insipid, and the intermediate and lower tones escaped me.”

monet paintings2.jpegMonet’s early and well-known paintings of water lilies are full of vibrant blue and purple tones, with clear and sharp lines. As his vision deteriorated, his portrayal of nature became more abstract, and increasingly infused with yellow and red tones.

When Monet’s cataracts became very advanced, he could no longer rely on his eyes to select the correct paint colors; he had to read the labels on the paint bottles to know which color was inside. This is because cataracts caused light to scatter within his eye, blurring his vision.

Monet eventually had cataract surgery, which allowed him to see blue and purple again. However, he wrote to his eye doctor complaining that he couldn’t see yellows and reds anymore, which frustrated him. In those days, cataract surgery was fairly new and couldn’t fully perfect vision.

Eventually, he wore tinted lenses to help correct his color vision problem.

Degas retinal diseaseRetinal Disease

Macular degeneration affects the central portion of the retina, called the macula. The main symptoms of macular degeneration are poor central vision, perceiving straight lines as distorted, and blurred vision.

Medical experts believe that Edgar Degas suffered from retinal disease. Furthermore, he frequently complained about his declining eyesight in letters.

When comparing Degas’ paintings from his 40s to the ones from his 60s, the lack of shading and less-refined lines are glaring and may have been due to the deterioration of his retina.

Strabismus

Strabismus, or an eye-turn, is a misalignment of the eyes. The most obvious symptom of strabismus is that the two eyes don’t point in the same direction. This condition can also cause double vision, lazy eye and poor depth perception.

Rembrandt, whose eyes appear to be misaligned in his self-portraits, was thought to have strabismus. It is speculated that he needed to close one eye to avoid double vision, allowing him to accurately replicate what he saw onto the canvas. This would have affected how he painted his own eyes.

What’s The Link Between Obesity And Age-Related Macular Degeneration?

senior woman macular degeneration 640It’s well known that obesity is a risk factor for developing serious health conditions like diabetes and cardiovascular disease. Now researchers are studying whether being obese raises the risk of age-related macular degeneration (AMD) — a leading cause of blindness in adults over the age of 60.

What’s Age-Related Macular Degeneration (AMD)?

AMD is a progressive eye disease that damages the center of the retina, called the macula. The macula is responsible for the central vision that focuses on detail. As it deteriorates, patients may notice blurry or dark spots in their central visual field. This can make it difficult to read, drive and recognize faces.

Other symptoms of AMD are distorted vision, difficulty adjusting from bright settings to dim ones, and colors appearing dull.

There are two forms of the disease: wet and dry.

Dry AMD is much more common and less severe than wet AMD, which usually sets in quickly and progresses more aggressively. Both forms can lead to legal blindness, but treatments can help slow their progression and minimize vision loss.

If you or a loved one has been diagnosed with AMD or experience any of the above symptoms, call and ask how we can help preserve your vision.

Does Obesity Affect AMD?

Researchers are investigating whether there is a link between obesity and AMD.

Some studies suggest that people with a BMI over 30 have double the risk of developing age-related macular degeration than those with a lower BMI.

However, a study published in the journal Retina found that obesity was a predictor for the development of late-stage AMD. In simpler terms, being obese accelerated AMD progression in those who had it or were at a higher risk of developing this serious eye disease.

Another study, published in BMC Ophthalmology, supports these findings. Obesity was found to be a significant factor in the development of late-stage AMD, but this study also showed that age, smoking, and a family history of AMD are higher predictive factors.

What’s the Bottom Line?

These studies indicate that maintaining a healthy weight may lower the risk of late-stage AMD.

To reduce your risk of developing AMD, or to slow its progression, we recommend you quit smoking, eat more leafy greens and ask your eye doctor about the potential benefits of taking a supplement called AREDS 2.

If you or a loved one has received a macular degeneration diagnosis, it can be scary — but we are here for you. Our team of highly trained eye doctors can provide you with cutting-edge treatments in a warm and friendly atmosphere.

Q&A

Q: #1: What treatments are available for AMD?

  • A: Although there isn’t yet a cure for AMD, treatments can help slow it down and even reverse eye damage. Treatment include eye injections, laser therapy, and vitamins. Your eye doctor will determine which treatment option is right for you.

Q: #2: How common is age-related macular degeneration?

  • A: Unfortunately, AMD is the most common cause of vision loss in people over the age of 60, affecting about 196 million people around the world. That number is expected to double, to over 400 million people by the year 2050. AMD is a leading cause of permanent vision loss and blindness across the globe.
