Ocular Complications of Hypovitaminosis A after Bariatric Surgery

Gastric bypass procedures can cause vitamin A deficiency leading to serious ocular complications, including xerophthalmia, nyctalopia, and ultimate blindness. The increasing incidence of obesity and gastric bypass procedures warrants patient and physician education regarding strict adherence to vitamin supplementation. Education is imperative to avoid detrimental ophthalmic complications resulting from hypovitaminosis A and to prevent a potential epidemic of iatrogenic xerophthalmia and blindness.
