Histoplasmosis occurs when airborne spores of the fungus Histoplasma capsulatum are inhaled. This microscopic fungus, which is found throughout the world in river valleys and soil where bird or bat droppings accumulate, is released into the air when soil is disturbed by ploughing fields, sweeping chicken coops, or digging holes.
The symptoms of histoplasmosis are often so mild that it can be confused as common cold. In fact, if you had histoplasmosis symptoms, you might dismiss them as those from a cold or flu, since the body's immune system normally overcomes the infection in a few days without treatment.
A serious form of the condition can threaten your life. If your infection shows any signs and symptoms, they would occur between three to 17 days after the exposure to the cause. An infected person may experience fever, chills, headache, muscle aches, dry cough and chest discomfort.
The only proven treatment for OHS is a form of laser surgery called photocoagulation. A small, powerful beam of light destroys the fragile, abnormal blood vessels, as well as a small amount of the overlying retinal tissue. The destruction of retinal tissue during the procedure can itself cause some loss of vision, this is done in the hope of protecting the fovea and preserving the finely-tuned vision it provides.
