A persistent ulcer of the cornea, found in elderly people [After Albert Mooren (1828-99), ophthalmologist in Dusseldorf, Germany].
A rare, inflammatory lesion of the peripheral cornea that causes significant eye pain and blindness if untreated. This condition is found in some patients with hepatitis C, other infectious diseases, or prior eye trauma or eye surgery. It may be an example of autoimmune molecular mimicry. Treatments include the use of immunosuppressant drugs, keratoplasty, or both.
