What is eye histoplasmosis?
Ocular histoplasmosis is possible complications of the type of pulmonary infection of molds. Air spores from fungus histoplasma capsulatum can connect to the inner lung lung lungs and may or may not cause immediate symptoms. If fungal spores are achieved by the bloodstream, they can travel into the eyes and insert into the choroid layers above the retina. People with eye histoplasmosis can experience a slight to severe loss of central vision due to inflammation of the blood vessels and scarring in the eyes. Treatment in the form of laser surgery may usually prevent further eye damage, but most people who develop eye histoplasmosis will not receive a vision they have already lost.
The exact mechanisms that migrate fungal spores from the lungs to the eyes are not known. In fact, there is usually no direct evidence that there are mushrooms in people at all in people who diagnose eye histoplasmosis. However, almost every person who has a disorder has the previous history of the fungal lung infection. After receiving contact with histoplasmand capsulatum may take several months or even years.
The choroid layer of the eye contains small blood vessels that feed the retina. Eye histoplasmosis causes inflammation in existing blood vessels and the growth of new, very fine blood vessels that are susceptible to blood leakage. As a result, scarring and lesions in the central part of the retina may occur. The affected eye has problems with sharp focus, which is required to read the text, establish eye contact or safe operation of the vehicle. Peripheral vision is usually left intact.
A person who believes that he may have symptoms of eye histoplasmosis should see an eye physician as soon as possible. The doctor can be able to see small stains in the eye called histo spots, which are small scars above the layer of choroids that are common in ocular histoplasmosis. A detailed test can also detect retinal swelling and excessive blood vessel growth.
antifungal drugs and anti -inflammatory summerChiva did not prove to be useful in the treatment of eye histoplasmosis. The most effective treatment is surgery called laser photocoagulation. During surgery, a high intensity laser beam is used to burn abnormal blood vessels. In most cases, photocoagulation is very effective in stopping future vision degeneration. However, it cannot restore lost vision. Specialized contact lenses and seating with trained vision specialists can be able to help some patients to see better and learn to overcome their handicaps.
