Corneal Ulcer
Introduction
A corneal ulcer is an open sore on the cornea (the clear layer in front of the iris and pupil) that is usually caused by an eye infection. Contact lenses, injuries, disorders, drugs, and nutritional deficiencies can also cause open sores (ulcers) to form on the cornea. Ache, foreign body sensation (the ache and foreign body sensation can be severe), redness, tearing, and light sensitivity are common symptoms. Doctors diagnose an ulcer based on the appearance of the person's cornea. Antibiotic, antiviral, or antifungal eye drops are usually given as soon as possible. (See also Herpes Simplex Keratitis .)
