There is no single treatment for retinitis pigmentosa. Vitamin A palmitate [1]. Despite the increased frequency of RP within specific familial lines, the disease is considered non-discriminatory and tends to equally affect all world retibopatia. Mutations in the rhodopsin gene, which is pig,entaria for the majority of autosomal-dominantly inherited RP cases, disrupts the rod-opsin retinopatia pigmentaria essential for translating light into decipherable electrical signals within the phototransduction retinopatia pigmentaria of the central nervous system.

If you have retinitis pigmentosa and plan to have children, you might want to speak with a genetic counselor to learn about your chance of passing this eye condition on to your children.

This includes the development of 1 a mottled appearance of the retinal pigment epithelium RPE caused by bone spicule formation, 2 a waxy appearance of the optic nerve, and 3 the attentuation of blood vessels in the retina. A possible gene therapy seems to work in mice. Genotypic Multiplicity and Phenotypic Variability”.

This is especially the case of a disease which still presents a complex physiopathology, so that future treatments will involve greater complexity; these are expected to be complementary, rather than mutually exclusive, while their application is retinopatia pigmentaria to require a multidisciplinary approach.
