Posner-Schlossman syndrome (glaucomatocyclitic crisis)

Posner-Schlossman syndrome (PSS) or glaucomatocyclitic crisis is a rare, typically unilateral recurrent inflammatory ocular hypertensive disease in which diagnosis can be challenging. An acute elevation of intraocular pressure is accompanied by or followed within a few days by a mild, often symptomless uveal inflammation. The mild nature of the uveitis at presentation of the first attack may go undetected. Medical treatment is indicated to prevent pressure-related optic nerve damage and to reduce inflammation. This report details a patient with Posner-Schlossman syndrome whose unilateral pressure elevation was initially treated as acute angle-closure glaucoma. He subsequently had several episodes of increased pressure over a two-year period. Diagnostic difficulties in this case are discussed.
