Fundus images of retinitis pigmentosa<unk> is a retinopathy which consists in the deterioration of the<unk> caused by the progressive death of its cells. There are several reasons for<unk>  including artery or vein occlusion, diabetic retinopathy, R.L.F./R.O.P. (retrolental fibroplasia/ retinopathy of prematurity), or disease (usually hereditary). These may present in many different ways such as impaired vision, night blindness,<unk>  detachment, light sensitivity, tunnel vision, and loss of peripheral vision to total loss of vision. Of the<unk>  degenerative diseases retinitis pigmentosa (RP) is a very important example. Inherited<unk>  degenerative disorders in humans exhibit genetic and phenotypic heterogeneity in their underlying causes and clinical outcomes. These retinopathies affect approximately one in 2000 individuals worldwide. A wide variety of causes have been attributed to<unk>  such as disruption of genes that are involved in phototransduction, biosynthesis and folding of the rhodopsin molecule, and the structural support of the<unk>  Mutations in the rhodopsin gene account for 25% to 30% (30% to 40% according to) of all cases of autosomal dominant retinitis pigmentosa (adRP) in North America. There are many mechanisms of<unk> attributed to rhodopsin mutations or mutations that involve or affect the function of rhodopsin. One mechanism of<unk> is rhodopsin overexpression. Another mechanism, whereby a mutation caused a truncated rhodopsin, was found to affect rod function and increased the rate of photoreceptor degeneration.
