Retinitis pigmentosa (RP) is the name given to a group of inherited conditions of the retina that all lead to a gradual progressive reduction in vision. Difficulties with night vision and peripheral vision are the first things that are noticed. Later, reading vision (detailed vision), colour vision, and central ('straight-ahead') vision are affected. The age at which symptoms start is variable and the rate of deterioration often varies - for example with the different genetic types - but is generally very slow with changes occurring over years rather than months. In approximately half of all cases there are other family members with RP. It affects approximately 1 in 3,000 to 4,000 people.

Retinitis pigmentosa is one of a group of inherited retinal diseases. Collectively they are the leading cause of blindness in the developed world. Inherited retinal diseases are the subject of our current appeal. Please help us combat this significant cause of blindness by making a donation now.
