Question:
What is ocular histoplasmosis?

Answer:
Histoplasmosis is caused by a soil-borne fungus prevalent in the Ohio and Mississippi River valleys. Exposure and antibodies to the fungus may be present in a majority of individuals living in these areas. Presumed ocular histoplasmosis syndrome (POHS) is the most common ocular disease associated. It is seen in retinal examination and appears as small "punched out lesions" or scars of the retina. It can affect vision if new blood vessels start growing under the macula or near the optic disc. If that happens treatment with laser or intraocular injections may be required.
