Retinitis pigmentosa--an overview.

Retinitis pigmentosa is a retinal pigment dystrophy of multiple genetic inheritance patterns affecting approximately .5% of the world population. It may be recognized clinically by observing specific ophthalmoscopic changes, as well as through psychophysical and electrodiagnostic testing. It may also be associated with several other genetic conditions. Basic research indicates that while there is no specific cure, certain precautions may prevent rapid acceleration of the disease process. This article presents an overview of retinitis pigmentosa, including its diagnosis and genetic patterns, and discusses various auxiliary aids and filters that may be helpful in protecting and increasing visual function in R.P. patients.
