Poor Vision from Copper Deficiency
1University of North Dakota School of Medicine and Health Sciences, 1301 North Columbia Rd, Grand Forks, ND, 58202-9037, USA. leslie.klevay@ndus.edu.
Purpose:
A dozen medical articles describe poor vision from copper deficiency. They are collected here along with some ideas about copper nutrition, epidemiology, patient evaluation and treatment.
Recent Findings:
Clinical descriptions have been brief. Severe vision loss of a middle-aged woman improved from 20/400 to 20/25 with copper replacement for 10 months. The optimal chemical form, dose, duration or route of copper repletion are defined poorly. Copper gluconate is the preferred supplement; several mg of elemental copper usually should be given daily for months. Superoxide dismutase in erythrocytes is one of the more sensitive tests of deficiency.
