Retinitis Pigmentosa is an inherited eye disease leading to death of the rod photoreceptors and subsequent death of the the cones due to oxidative damage, resulting in blindeness. Several mutations, particularly in the gene coding for rhodopsin, have been found to cause Retinitis Pigmentosa. It can be inherited as an autosomal dominant, autosomal recessive, or X-linked recessive disorder..
Retinitis Pigmentosa is usually diagnosed at a young age as a teen or a young adult..

- Night Blindness
- Tunnel Vision
- Aversion to glare
- Blurred Vision
- Loss of central vision (in more serious case)
Although no effective treatments to cure the disease have been discovered, a number of studies have inferred that treating a patient with antioxidants such as sizeable doses of Retinyl palmitate (vitamin A palmitate) will slow down the progress of the disease. There are compllications to this treatment, retinyl palmitate can cause serious damage to a patients liver, so treatment benefits have to be weighed against the risks.
