The front of the eye is covered with a thin, transparent membrane called the cornea, which protects the interior of the eye. If there is a break or defect in the surface layer of the cornea, called the epithelium, and damage to the underlying stroma, a corneal ulcer results. The ulcer is usually caused by microrganisms, which gain access to the stroma through the break in the epithelium.
Corneal ulcers generally heal well if treated early and aggressively. However if neglected, corneal clouding and even perforation (a hole in the cornea) may develop, resulting in serious loss of vision and possibly loss of the eye. Corneal ulcers are a serious vision-threatening condition and require prompt medical attention. DO NOT WAIT to see your eye doctor if you experience any of the symptoms below.

Corneal ulcers are a serious vision-threatening condition and require prompt medical attention. If left unattended, corneal ulcers may penetrate the cornea allowing infection to enter the eye, which can cause permanent loss of vision and possible loss of the eye. Your eye doctor can identify corneal ulcers by examining your eyes with magnifying instruments and if necessary by taking a culture to identify infection. Your doctor will check your eye, including under your eyelid, to make sure there are no foreign materials present.
If treated early, corneal ulcers are usually curable. They are typically treated with antibiotic eye drops, often several different types. Sometimes, topical steroids will also be used to decrease the risk of scarring and inflammation. Expect to be seen for frequent follow-up visits.
