Retinis Pigmentosa


The Retinitis Pigmentosa (RP) is a clinically and genetically heterogeneous group of retinal degenerations inherited from a person’s parents of primary incidence with autosomal dominant and recessive transmission modality, X-\linked and mitochondrial. It was described for the first time by Donders in 1857. The definition is per se misleading since it refers to an inflammatory process that does not play a primary role in this pathology. It is a progressive disorder that entails the death of the rods followed by the loss of the cones; however, the loss of both types of photoreceptors can also occur simultaneously.


The nutritional therapy consisting in the administration of vitamins and other products (Vitamin A, omega 3 and luthein) can be useful only for those patients suffering from specific forms of retinitis pigmentosa (RP). For the time being no pharmacological therapies exist for slowing down or stopping the progressing of retinal atrophy, even though there are many clinical trials suitable to test new drugs and gene therapies for the treatment of this pathology, which are already being conducted in a restricted population of patients suffering from this serious disease.
