Abstract：
UNASSIGNED: 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.
UNASSIGNED: 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.
UNASSIGNED: 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.

摘要：
■在美国，联合营养缺乏是视力丧失的罕见原因。值得注意的是,维生素A缺乏可导致夜盲症，但很少导致双侧中央视力丧失。这些症状的组合是不寻常的，尽管可能被低估了。
■我们报告了一例罕见的由维生素A联合引起的双侧中心性视力丧失和夜盲症，锌，和铜缺乏，可能是在减肥手术和饮酒后。补充矿物质和维生素后，患者的视力显著改善，并在1个月内恢复至基线水平。以前在英语眼科文献中从未报道过这种维生素和矿物质缺乏的特定多重组合导致的视力丧失。
■鉴于美国和国外的减肥手术和酒精使用率上升，临床医生应该意识到，进行性近视和双侧中心性视力丧失的组合可能是由营养缺乏引起的。在这种情况下，筛查和补充维生素和矿物质缺乏症可能会导致视力丧失的戏剧性逆转。
