ABSTRACT
Introduction:
Combined nutritional deficiency is an uncommon cause of vision loss in the USA. Notably, vitamin A deficiency can produce nyctalopia but rarely causes bilateral central vision loss. The combination of these symptoms is unusual, although likely underreported. Case Presentation We report an exceptionally rare case of bilateral central vision loss and nyctalopia caused by combined vitamin A, zinc, and copper deficiency, likely following bariatric surgery and alcohol use. Following mineral and vitamin supplementation, the patient's vision improved significantly and returned to baseline within 1 month. Vision loss resulting from this specific multicombination of vitamin and mineral deficiency has never been reported previously in the English-language ophthalmic literature.Conclusion:
Given rising rates of bariatric surgery and alcohol use in the USA and abroad, clinicians should be aware that the combination of progressive nyctalopia and bilateral central vision loss may be produced by combined nutritional deficiency. Screening and supplementation of both vitamin and mineral deficiency may result in dramatic reversal of visual loss in such cases.
