PURPOSE: We report a case of spontaneous Descemet membrane detachment (DMD) in a patient with a history of necrotizing scleritis and discuss the management approach and outcome.
METHODS: This was a case report and review of literature.
RESULTS: A 50-year-old man with a history of rheumatoid arthritis, ankylosing spondylitis, and necrotizing scleritis on systemic methotrexate, rituximab, and prednisone presented with 6 weeks of photophobia, pain, and decreased vision in his left eye. Visual acuity on presentation was 20/80 in the left eye, and intraocular pressure was 18 mm Hg. Slit lamp examination demonstrated scleral injection most significantly in an area of superonasal epithelialized scleral thinning with underlying uveal visibility, indicating prior necrotizing scleritis. Bullous corneal edema extended from the limbus superonasally into the visual axis. The remainder of the anterior and posterior segment evaluations was unremarkable. Anterior segment optical coherence tomography confirmed the presence of DMD underlying the area of corneal edema. The patient was treated with an increased dose of oral prednisone with subsequent taper for systemic autoimmune control given active nonnecrotizing scleritis, followed 2 months later by air bubble injection in the anterior chamber and face-up positioning for 2 days. This led to reattachment of Descemet membrane and complete clearance of corneal edema, with improvement of vision to 20/25 on follow-up.
CONCLUSIONS: This is the first report of spontaneous DMD in a patient with a history of necrotizing scleritis. A possible mechanism may include shearing forces secondary to scleral ectasia, which may result in focal Descemet membrane tears and subsequent detachment.
