Phlyctenular Keratoconjunctivitis
Introduction
Phlyctenular keratoconjunctivitis is an eye disorder that involves an immune reaction of the cornea (the clear layer in front of the iris and pupil) and conjunctiva (the membrane that lines the eyelids and covers the white of the eye) to bacteria. Small, yellow-gray, raised bumps form on the eye. Common symptoms are redness of the eye, blurred vision, sensitivity to bright light, a sensation of a foreign object trapped in the eye, and sometimes visible flakes of dead skin at the edges of the eyelids. Doctors diagnose phlyctenular keratoconjunctivitis based on the eye's appearance. Treatment is with eye drops or eyelid scrubs. Phlyctenular keratoconjunctivitis is not an infection. It is an immune reaction to bacteria that are on or around the eyes. Some of the bacteria that trigger this disorder are staphylococci, and rarely, tuberculosis, andChlamydia. This disorder is more common among children.
