Research output: Chapter in Book/Report/Conference proceedingChapter


Retinitis pigmentosa (RP) is caused by a large number of genetic defects that result in a characteristic pattern of degeneration of the rod and cone photoreceptors and the retinal pigment epithelium. RP is a heterogenous disease that can be classified in different ways. This article discusses the different categorizations of RP based on inheritance, genetic defect, and clinical presentation.
