Ocular Histoplasmosis

Ocular histoplasmosis is a retinal disease that follows exposure to a fungus called histoplasma capsulatum that is commonly found in temperate, moist environments such as along river valleys in the eastern United States. Most people who live in the Mississippi River valley and other similar river valleys have inhaled this fungus, which is aerosolized. Only a subset will go on to develop an immune response that leads to retinal scarring and sometimes ingrowth of blood vessels under the retina with leakage and bleeding that can harm vision.
