title: Peripheral ulcerative keratitis: Our challenging experience.
abstract: A 52 year old male presented with peripheral ulcerative keratitis in the right eye. Patient's history included retinitis pigmentosa, pseudophakia (right eye), cataract (left eye), bilateral partial deafness, ischemic heart disease, hypertension, type 1 diabetes mellitus, depression, hyperparathyroidism, hypertriglycemia and renal failure. The patient was on weekly hemodialysis. The peripheral corneal ulceration remained stable until he developed sudden and rapid thinning after eight months of regular follow up and management. Laboratory investigations including immunological studies were negative and we had to rely on treatment based on clinical signs, including the visual acuity, size, depth and staining of the ulcer and perilimbal, episcleral, scleral, corneal and anterior chamber reactions. The patient was treated with medical and conservative approaches and the eye was protected with a plastic shield to avoid injury. Despite our efforts, the patient perforated his eye due to a trivial trauma during sleep. He was managed successfully with cyanoacrylate glue and a bandage contact lens. The anterior chamber reformed after the perforation was sealed and the patient is on a regular follow up with a multidisciplinary approach.
