Below see a snippet from an article I wrote for the NDNR.
“Retinitis pigmentosa (RP) is a heterogeneous group of inherited retinal disorders that are characterized by progressive degeneration of the photoreceptors and the underlying retinal pigment epithelium. Given its prevalence of 1 case among 3000 to 5000 individuals, RP is the most common group of inherited retinal diseases. Signs and symptoms often include slowly progressive bilateral loss of night vision. A ring scotoma is often present on perimetry, which tends to widen the decreasing central vision. Dark “bone spicule” pigment changes are frequently seen in the retina. Diagnostic investigations include perimetry, dark adaptation testing, and electroretinographic studies. ”
