Corneal Abrasion / Corneal Disease

Corneal Abrasion

A corneal abrasion is a scrape or scratch on the clear front surface of the eye that can occur as a result of exposure to a foreign object, ultraviolet light, infection or from being hit in the face. Patients with this condition may experience a sensation of having something in their eye, along with tearing, blurred vision and eye pain when exposed to bright light.

Depending on the cause of the condition, patients may be able to treat a corneal abrasion at home by rinsing the eye, using artificial tears or taking over-the-counter medications. If symptoms persist, antibiotic eyedrops or ointment may be needed to relieve inflammation. Your doctor may also recommend patching, pain medication or eyedrops to reduce muscle spasms.

It is important for patients with corneal abrasion to avoid touching or rubbing their eyes. In most cases, corneal abrasion can be effectively treated with no permanent complications.

Corneal Disease

The cornea is a thin, clear, spherical layer of tissue on the surface of the eye that provides a window for light to pass through. In a healthy eye, the cornea bends or refracts light rays so they focus precisely on the retina in the back of the eye.

There are many diseases that can affect the cornea, causing pain or loss of vision. Disease, infection or injury can cause the cornea to swell (called “edema”) or degrade (become cloudy and reduce vision). Common diseases and disorders that affect the cornea include:

  • Allergies
  • Bullous Keratopathy
  • Conjunctivitis (“Pink Eye”)
  • Dry Eye
  • Corneal Dystrophies including Fuchs’ Dystrophy and Lattice Dystrophy
  • Glaucoma (High Eye Pressure)
  • Infections
  • Keratitis (Viral Inflammation)
  • Keratoconus
  • Ocular Herpes
  • Pterygium
  • Shingles (Herpes Zoster)
  • Stevens-Johnson Syndrome

Treatment for corneal disease can take many forms, depending on the underlying problem as well as the patient’s preferences. Some conditions resolve on their own and many can be treated with medication. If the cornea is severely damaged or if there is a risk of blindness, a corneal transplant may be recommended to preserve vision.
