Histoplasmosis infection is often so mild that it produces no clear symptoms. Any symptoms are often like those from a common cold. In fact, if you had histoplasmosis symptoms, you might think you just had a cold or flu. This is because the body’s immune system normally beats the infection in a few days without treatment.
POHS often has no symptoms in its early stages. You can have POHS without knowing it. Tiny scars called histo spots remain at the infection sites after the inflammation is gone. These histo spots can be the only way to tell you had the infection. Histo spots do not generally affect vision. Although ophthalmologists don’t know why, they can cause complications years or even decades later. We do know that there is a connection between histo spots and the growth of abnormal blood vessels underneath the retina.
Histoplasmosis symptoms may appear if these abnormal blood vessels spread to areas of the retina that are vital for good vision. The symptoms for POHS are similar to macular degeneration symptoms.
These symptoms include:
- blank spots in your vision, especially your central vision
- distorted vision, so that straight lines appear bent, crooked or irregular
- size of objects may appear different for each eye
- colors lose their brightness; colors do not look the same for each eye
- central light flashes or flickering
If you have any of the symptoms of histoplasmosis, you should see an ophthalmologist.
