Introduction: Retinitis Pigmentosa (RP) is a chronic condition corresponding to the retinal dystrophies having an inherited, slow and progressive character where the function of the photoreceptors and pigmentary epithelium are affected diffuse and primarily, mainly characterized by the peripheral and nocturnal loss of vision; it provokes disorders of the visual field and subnormal extinct electroretinogram. Objective: To know the results of the Clinical-ophthalmologic and genetic characterization of Retinitis Pigmentosa in Pinar del Rio Province, Cuba. Method: A fundamental, applied, descriptive and cross-sectional research including the universe of the 257 cases suffering from Retinitis Pigmentosa attended at "Tercer Congreso" Hospital in Pinar del Rio during December 1992 to December 2008. Results: The current provincial rate of RP is 3.51/10000 inhabitants with a prevalence of 1.2845. Atypical form prevailed (70.1%), autosomic recessive pattern (53.4%), early onset (51.8%) and the stages 1-2 (64.2%).
