Abstract

Presumed ocular histoplasmosis syndrome (POHS) is a subset of multifocal choroiditis that occurs secondary to infection with the yeast form of , a dimorphic fungus commonly found in bird and bat fecal material. The peculiarities of the disease are the following: atrophic chorioretinal scars, peripapillary atrophy (PPA), absence of vitritis, and choroidal neovascularization (CNV), which represents the most dangerous sequela. The disease can be unilateral or bilateral.
