Corneal Ulcer
Symptoms of Corneal Ulcer
Corneal ulcers cause redness, pain, usually a feeling like a foreign object is in the eye (foreign body sensation), aching, sensitivity to bright light, and increased tear production. The ulcer often appears as a white or dull and grayish spot on the cornea. Sometimes, ulcers develop over the entire cornea and may penetrate deeply. Pus may accumulate behind the cornea, sometimes forming a white layer at the bottom of the cornea (called a hypopyon). The conjunctiva usually is bloodshot. The deeper the ulcer, the more severe the symptoms and complications. Corneal ulcers may heal with treatment, but they may leave a cloudy scar that impairs vision. Other complications may include deep-seated infection, perforation of the cornea, displacement of the iris, and destruction of most or all of the tissue in the eye socket.
