title: [Carotinoid retinopathy. III. Reversibility].
abstract: Twenty-five patients (erythropoietic protoporphyria 23, polymorphous light eruption 1, "cosmetics" 1) were re-examined 2-10 months after therapy with beta-carotene and canthaxanthine was discontinued. Dark adaptation and ERG parameters had normalized, whereas crystalline retinopathy and pigment epithelial defects showed no signs of reversibility.
