Ocular histoplasmosis: clinicopathologic correlation of 3 cases

Abstract

The eyes of three patients followed clinically for many years with a diagnosis of macular disciform scarring, secondary to ocular histoplasmosis, were studied histopathologically. A fibrovascular scar interposed between the choroid and retina was observed in all cases. Vessels passing from the choroid through defects in Bruch's membrane into the nodule were demonstrated. Theories of the pathogenesis of the lesion are discussed.
