KERATITIS, or corneal inflammation, can be caused by myriad conditions ranging from a simple abrasion to infection with viruses (such as herpes simplex type 1), bacteria, fungi, or protozoa. These microorganisms enter the cornea through a defect in the corneal epithelium, where they proliferate and cause ulceration. Keratitis must be treated because it can cause permanent corneal scarring, perforation, and blindness.

In this article, I'll focus on bacterial and fungal keratitis.
