Can histoplasmosis cause vision problems?

Ocular histoplasmosis syndrome (OHS) is an eye condition that can develop in people who have a lung infection called histoplasmosis. If you have histoplasmosis, the infection can move from the lungs into the eyes, leading to vision loss.

What causes POHS?

How long does ocular histoplasmosis last?

Systemic histoplasmosis produces an influenza-like illness with fever and weakness that usually lasts about two weeks. After recovery, the infection can leave small, usually harmless scars throughout the body. The eye can be involved and the scars can be detected during an examination of the retina.
