What is Retinitis pigmentosa?
Retinitis pigmentosa is a disease that affects
night vision and peripheral vision. The disease starts with
decreased night vision progressing to diminished peripheral
vision. The
rate of decline varies depending on the genetic makeup of
the disorder and also varies somewhat in individuals.
Causes of Retinitis pigmentosa
Retinitis pigmentosa is a genetic disorder that is usually
hereditary.
The light sensitive retinal cells, known as Rods,
are responsible for vision in dim light. The Rods in patients
with retinitis pigmentosa will gradually deteriorate so
that vision at night
becomes
more difficult.
Diagnosis of Retinitis pigmentosa
Symptoms start with decreased night vision, usually occuring
early childhood. These symptoms usually progress
to a diminishing of peripheral vision. Later stages of
retinitis pigmentosa, will leave only the central area of
vision and slight peripheral
vision.
Treatments for Retinitis pigmentosa
There is some belief that vitamin A may delay vision
loss.
Research is being carried out examining possible treatments
including retinal implants and
medication.
