Retinitis Pigmentosa

retinitis-pigmentosa

Retinitis Pigmentosa (RP) causes a loss of photoreceptor cells (rods and cones), of the retina. It is characterized by night blindness, the gradual loss of peripheral vision, and may lead to eventual blindness. Since it is often an inherited disease, RP affects males more than females.


Signs and Symptoms

People with RP generally first notice difficulty seeing in dim lighting and gradually lose peripheral vision. In many cases, RP is diagnosed during childhood when the symptoms begin to become apparent. However, depending on the progression of the disease, it may not be detected until later in life.


Detection and Diagnosis

Electroretinography is a study of the nerve tissue of the retina and is used to confirm RP. Dilated exam and Fluorescein Angiography are also necessary to evaluate the progression of RP.


Treatment

There is no effective treatment or cure for RP. Vision loss caused by RP is permanent and cannot be reversed.
