What You Should Know About Corneal Disease

The cornea, the eye’s transparent cover, refracts light, which enables the eye to see clearly. A healthy cornea is vital to good eyesight, so damage to the cornea can cause pain, sensitivity to light, blurriness, inflammation, headaches, and vision loss.

Conditions and diseases harmful to the cornea include:

  • Injuries and trauma
  • Keratitis, an inflammation of the cornea resulting from an injury, bacteria, viruses, fungi, or parasites. (One form, neurotrophic keratitis, is a rare degenerative disease characterized by corneal numbness, thinning, ulceration, and perforation.)
  • Dry eye, resulting from the eyes not producing enough tears or tears of subpar quality
  • Shingles, herpes, and other viruses
  • Iridocorneal endothelial syndrome, causing corneal swelling, glaucoma, and changes in the iris
  • Pterygium, a growth of tissue on the cornea
  • Stevens-Johnson syndrome (erythema multiforme major), a serious skin disorder that also causes conjunctivitis, corneal blisters and erosions, holes in the cornea, and painful blisters on the eyelids
  • Corneal dystrophies (such as keratoconus, lattice corneal dystrophy, map-dot-fingerprint dystrophy, and Fuchs’ dystrophy), which cause parts of the cornea to become cloudy starting in childhood
  • Allergies and minor scratches

Lowering Risks to the Cornea

According to the National Institutes of Health’s National Eye Institute, you can lower the risk of corneal injuries by wearing protective eyewear while playing sports, doing yard work, working on home repairs, using machines, and handling chemicals. You can prevent keratitis and other corneal infections by properly cleaning, disinfecting, and storing your contact lenses.

Diagnosing Corneal Damage When It Does Occur

If you suspect you have sustained corneal damage of any kind, contact Dr. Ben Giddens, Dr. Andrea Kozma and Dr. Brandon Pham to examine for corneal abrasions and corneal diseases. This is important because many eye diseases have no early symptoms or warning signs. Indeed, getting a dilated eye exam is important even if your eyes seem healthy.

Treating Corneal Diseases

Treatment options depend on the medical condition. They include:

  • Eye drops and ointments
  • Cenegermin, a medication for treating neurotrophic keratitis
  • Oral antiviral medications
  • Laser surgery to treat corneal erosions and dystrophies by reshaping and restoring the cornea
  • Partial corneal transplant, in which one or two layers of the cornea are removed or are replaced by a layer from a donor
  • Corneal transplant for some patients with keratoconus, severe corneal scarring, certain corneal dystrophies, edema after cataract surgery, and any failure of the cornea after eye surgery
  • Artificial cornea for those who cannot undergo a corneal transplant

One of the most common ways to treat corneal problems is with scleral contact lenses, which vault over the cornea and rest upon the sclera, the eye’s white surface. These customized lenses can help patients with corneal abrasions, diseases, and injuries by protecting the cornea’s surface and keeping the cornea hydrated. Scleral lenses also allow the cornea to recover from a corneal transplant, and are the preferred treatment for keratoconus, severe dry eye, and other conditions.

At Giddens Optometry, Dr. Ben Giddens, Dr. Andrea Kozma and Dr. Brandon Pham diagnose corneal conditions and prescribe scleral lenses and other treatments for patients in Georgetown, Limehouse, Acton, Halton Hills, and throughout Ontario.

Hello friends, I have retired!

I had 37 years of good fun in Georgetown and loved the gift of meeting so many warm and friendly people! I am very sorry that I didn’t have the time to chat with everyone about my exact plans, and felt guilty over that at times. It was not an easy task. If anyone wants, or needs to contact me, please send an email to my office and I will reply.

I am 66 years old and still feel like I am in good health. My wife died of cancer in 2021 but I have good friends and family and a fun life. I recently moved back to Toronto which is where I grew up as a teenager. I have an active outdoor life and have many ski trips and travel plans in front of me. Lots of interests and activities to explore with an overriding sense that I am a lucky guy. I am also a grandfather now.

I have always tried to employ staff and optometrists who have a heart. I think that is where the office is at today and I hope it continues. Everyone knows their work, and the heart matters.

Ben.
