Clinical Comment

Retinitis Pigmentosa (RP) is the most common form of hereditary retinal dystrophy characterised by photoreceptor degeneration. RP manifests with initial night blindness and tunnel vision, followed by secondary loss of cone photoreceptors, leading to reduced visual acuity and macular degeneration. The onset and progression of RP and the severity of symptoms can vary significantly between patients, even within the same family. More than 200 different forms of RP are known. In 60 to >80% of RP patients a genetic predisposition can be identified (depending on the population and clinical preselection), which can be inherited according to all classical inheritance or in a few cases digenically. There is sometimes incomplete penetrance and differential clinical expression. An inconspicuous genetic finding does not mean that the suspected clinical diagnosis can be excluded with certainty.
