Copper metabolism in retinitis pigmentosa.
Clinically and electrophysiologically confirmed cases of primary retinitis pigmentosa have been investigated regarding their copper metabolic state. It is observed that these patients show a normal or near normal serum copper concentration, very low plasma caeruloplasmin concentration, and a very high copper urinary excretion. A similarity between this condition and hepatolenticular degeneratio...
متن کاملCopper metabolism in retinitis pigmentosa patients.
Serum copper, ceruloplasmin, and urinary copper were estimated in 13 normal subjects and 24 patients with primary retinitis pigmentosa. The serum copper levels in patients appeared to be higher and ceruloplasmin levels lower than in the normal subjects. The patients seem to fall into 2 categories with regard to urinary copper. About a third of them excreted 2-4 times more copper in the urine, w...
متن کاملCopper metabolism in American retinitis pigmentosa patients.
Serum copper, serum caeruloplasmin, and urinary copper excretion were measured in 38 American patients (and 15 family members) with recessive, dominant, and X-linked forms of retinitis pigmentosa. No abnormalities were found, in contrast to the findings of a recent study on Indian patients. Our data argue against a role for copper metabolism in ordinary retinitis pigmentosa.
متن کاملClinical copper metabolism parameters in patients with retinitis pigmentosa and other tapeto-retinal degenerations.
Reports have appeared of abnormal copper metabolism in retinitis pigmentosa, and of a family with vitelliform retinal degeneration in which other members suffered from hepatolenticular degeneration. In the present study 15 patients with retinitis pigmentosa, 4 with various other retinal degenerations, and 1 with a family disposition to retinitis pigmentosa were examined. The copper concentratio...
متن کاملRetinitis pigmentosa.
Hereditary degenerations of the human retina are genetically heterogeneous, with well over 100 genes implicated so far. This Seminar focuses on the subset of diseases called retinitis pigmentosa, in which patients typically lose night vision in adolescence, side vision in young adulthood, and central vision in later life because of progressive loss of rod and cone photoreceptor cells. Measures ...
