Presumed Ocular Histoplasmosis Syndrome (POHS) occurs when the fungus Histoplasma capsulatum infects the eyes. Timely care can prevent permanent vision issues.
Presumed ocular histoplasmosis syndrome (POHS) occurs secondary to infection with the yeast form of Histoplasma capsulatum. The disease is characterized by atrophic chorioretinal scars, peripapillary atrophy (PPA) , and the absence of vitritis.

Presumed ocular histoplasmosis syndrome (POHS) is a chorioretinal disease that is asymptomatic in the majority of cases. However, the condition may progress to peripapillary atrophy, chorioretinal lesions, choroidal neovascularization (CNV), disciform macular scars, and, ultimately, visual loss.
People with POHS can have: Small white spots that can appear deep inside the eye. Only an eye care professional can identify these spots. Choroidal neovascularization (new blood vessels form in the eye). This condition can cause vision loss. One study showed that 1 in 4 people with POHS had choroidal neovascularization.
Presumed ocular histoplasmosis syndrome (POHS) is an inflammatory, multifocal chorioretinal disorder. It was initially called ocular histoplasmosis syndrome because of its prevalence in areas with endemic histoplasmosis infection.
