Frequently Asked Questions About Keratitis

Keratitis is a common ailment marked by inflammation of the cornea, the transparent layer forming the front of the eye. The cornea is the powerhouse of the eye. Its curved shape bends light rays, accounting for two-thirds of the eye’s total power. This thin membrane is about 0.5 millimeters thick and sits on top of an aqueous fluid. Inflammation of the cornea causes redness, pain, and blurry vision.

What are the symptoms of keratitis?

Eye redness, pain, excess tears or discharge, difficulty opening the eye due to pain or swelling, and burred or decreased vision are all symptoms of keratitis. The condition may also cause photophobia or sensitivity to light. Upon onset, keratitis may simply feel like something is in the eye though the area is clear of debris.
