Interstitial keratitis is a serious eye disorder that involves inflammation of the middle layers of the cornea (the clear layer in front of the iris and pupil). It usually occurs in people who have had eye infections.
Symptoms include tearing, eye pain, blurred vision, and increased sensitivity to bright light in one or both eyes.
Diagnosis is by a doctor's evaluation and blood tests to rule out other diseases.
Doctors treat the underlying infection.

An eye examination
Blood tests
Doctors suspect interstitial keratitis when they see an affected cornea in a person who also has a history of an infection such as syphilis. To examine the cornea, they usually use a slit lamp (an instrument that enables doctors to examine the eye under high magnification).
Blood tests and other tests for syphilis, Lyme disease, and the Epstein-Barr virus are also done. People with interstitial keratitis and normal blood tests should be evaluated for Cogan syndrome.
