URINARY METABOLIC STUDIES IN HEREDITARY MACULAR DEGENERATION

Urinary metabolic studies by means of high-voltage paper electrophoresis (HVPE) and some qualitative chemical tests were performed in 40 patients in a family with hereditary macular degeneration and in 40 nonaffected members of the same family. No biochemical abnormalities were observed in the examined urine samples. The results are discussed with regard to earlier published reports of aminoaciduria in hereditary macular degeneration.
