Retinitis pigmentosa (RP)
Retinits pigmentosa (RP) is a degenerative retinal disease. The main symptoms are night blindness, glare sensitivity and visual field loss. Primarily affected are the light-sensitive cells of the retina (photoreceptors) of the "rod" type, which are present outside the center of the retina and most densely in the periphery. "Rods" are responsible for light/dark vision and are active in twilight/night. Visual field loss usually begins in the retinal periphery, and results in what is called "tube or tunnel vision". The clinical course can vary widely even within the same family. Genetic causes for non-syndromic RP have been identified in over 60 different genes.
In quite a few patients, RP occurs in the context of a superordinate syndrome (syndromic RP), e.g.:
Usher syndrome: RP and hearing loss
Bardet-Biedl syndrome: RP and obesity, extra toes/fingers
Alström syndrome: RP and cardiomyopathy, metabolic abnormalities
In Leber's congenital amaurosis (LCA), marked retinal dystrophy is present from birth.
Since 2018, a first viral gene therapy (Luxturna) is available for RP/LCA patients with disease-causing gene variants in the RPE65 gene.
