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, retinitis pigmentosa affects males more than females. 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

Retinitis pigmentosa is usually diagnosed with an ophthalmoscopy. A test called electroretinography may also be ordered to study the nerve tissue of the retina.  Fluorescein Angiography may also be ordered to assess the circulation of the retina.
