The front portion 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 microorganisms, 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 a serious loss of vision and possibly loss of the eye. Corneal ulcers are a serious vision-threatening condition and require prompt medical attention.

“Been going here for 9 years! I love the workers who have been there for a while. Some new workers take time to get things right, but that’s understandable! I definitely recommend this place to friends!” – Ashley A.
“Saw Dr Kim at the Stockton location and it was one of the best medical appointments I’ve experienced. Dr. was thorough with exam and all explanations. With C-19 they had the cleaning and sanitizing down. Very well run office, thank you.” -Julie B.
How are Corneal Ulcers Diagnosed?
Corneal ulcers are a serious vision-threatening condition and require prompt medical attention. If left unattended, corneal ulcers may penetrate the cornea allowing an infection to enter the eyeball, which can cause permanent loss of vision and possible loss of the eye. One of our doctors at Center Valley Eye Medical group can identify corneal ulcers by examining your eyes with magnifying instruments and performing a culture study to identify infection.One of our doctors will check your eye, including under your eyelid, to make sure there are no foreign materials present. Depending on the initial exam, fluorescein dye may be used to identify the corneal defects. A test called the Seidel test (painting the wound with dye and observing for leakage) may be performed to uncover possible deeper injuries.
How are Corneal Ulcers Treated?
If treated early, corneal ulcers are usually curable in two to three weeks. They are typically treated with antibiotic eye drops. Sometimes, topical steroids will also be used to decrease the risk of scarring and inflammation.
