Peripheral ulcerative keratitis in sarcoidosis: a case report.

Purpose: To document a case of peripheral ulcerative keratitis (PUK) that progressed to corneal perforation in the setting of recently diagnosed sarcoidosis.

Design: Observational case report.

Methods: A 42-year-old white woman presented with a 2-day history of tearing and decreased vision OD, secondary to PUK with corneal perforation. Slit-lamp evaluation revealed bilateral peripheral corneal thinning with vascularized scarring. History, clinical examination, chart review, peripheral lamellar keratoplasty, serologies, and bronchoscopy with biopsy were performed.

Results: After lamellar keratoplasty, visual acuity was 20/400 OD and 20/20 OS. She was treated with oral prednisone and high-dose Cytoxan therapy. One year postperforation, she received a limbus-to-limbus penetrating keratoplasty OD. One year after penetrating keratoplasty, the patient's BCVA OD is 20/40. She has stable scarring OS. Workup has revealed serologic and pathologic evidence of sarcoidosis without evidence of any other seropositive vasculitic disease.

Conclusion: This patient represents the first known case report of PUK in sarcoidosis. Oral Cytoxan, steroids, and topical cyclosporine have stabilized the disease process in this patient.
