Painless Mooren’s ulcer: A case report

Mooren’s ulcer is characterized by painful peripheral corneal ulceration of unknown etiology. The disease generally begins with intense limbal inflammation and swelling in the episclera and conjunctiva. Corneal changes begin within 2-3 mm from the limbus, first appearing as grey swellings that rapidly furrow, affecting the superficial one-third of the cornea and then proceeding circumferentially and centrally over 4-12 months. We report a case of 70 year old, male who came to ophthalmology OPD with symptoms resembling peripheral ulcerative keratitis, which was later diagnosed as Mooren’s ulcer. Patient had all features of Mooren’s ulcer except for pain. On slit lamp examination in right eye, crescent shaped corneal ulceration involving limbus. All his etiological investigations were negative which ruled out other differential diagnosis. The patient was treated for Mooren’s ulcer to which he responded well.
