Abstract
A patient presented with a posterior uveitis. An inferior plaque of retinal exudation was seen. Full investigation failed to establish a cause until six weeks later, when cryptococcal meningitis developed. The patient was immunocompetent. Exudation in relation to retinal vessels is unusual in idiopathic posterior uveitis, and cryptococcosis should be considered in the differential. Diagnosis is by lumbar puncture or vitreous aspiration.
