Caption

Corneal ulcer (green, just below pupil) on the eye of an 67-year-old woman with microbial keratitis. The yellow and green staining is caused by a fluorescein dye, which allows the ulcer to be seen. A corneal ulcer is an infected break in the surface of the eye that fails to heal and becomes inflamed. In this case the ulcer was caused by microbial keratitis, an infection of the cornea (the transparent membrane covering the front of the eye). Treatment depends on the infectious agent present; for example, bacterial ulcers are treated with antibiotics.
