Superficial punctate keratitis

Superficial punctate keratitis

 

Superficial punctate keratitis is death of small groups of cells on the surface of the cornea (the clear layer in front of the iris and pupil).

 

In superficial punctate keratitis, the eyes are usually painful, watery, sensitive to bright light, and bloodshot, and vision may be slightly blurred. Often there is a burning, gritty feeling or a feeling as if a foreign object is trapped in the eye. When ultraviolet light causes the disorder, symptoms usually do not occur until several hours after exposure, and they last for 1 to 2 days.
