Details
The cause of this disease was long considered to be multifactorial and not clearly understood. However, recent research suggests it is autosomal dominant, and a test is available. CSK is usually a progressive condition, effecting both eyes. The lesions that develop are not usually symmetrical nor are they usually painful. Severe cases can cause blindness. A diagnosis is usually established by ophthalmic examination of the eye.

The etiology of this disease is multifactorial and not clearly understood. CSK is usually a bilateral progressive condition, however the lesions are not usually symmetrical nor are they usually painful. Signs include pigmentation and vascularization of the cornea (extension of blood vessels onto the cornea). It is usually first seen at the lateral (temporal) limbus (the junction between the cornea and sclera), although it eventually can extend from any part of the limbus to cover the entire cornea. Severe cases can cause blindness. A diagnosis is usually established by ophthalmic examination of the eye.
