Abstract
While bariatric surgery confers significant weight reduction and control of metabolic diseases, its effect on diabetic retinopathy (DR) and other eye-related conditions remain a topic of much debate. Studies have shown conflicting results with regards to eye health in general following bariatric surgery, with reports of diabetic retinopathy improvement on one hand versus ophthalmological complications such as early worsening of diabetic retinopathy (EWDR), nyctalopia, xerosis, corneal ulceration, and permanent blindness on the other. Prolonged uncontrolled diabetes, the paradoxical effect of sudden significant reduction of blood glucose in the immediate hours following bariatric surgery, nutritional deficiency, and hypovitaminosis have all been cited as plausible causes for visual impairment in patients having undergone bariatric surgery. Efforts undertaken to identify and prevent deterioration of sight following bariatric surgery should be a concerted one with the involvement of ophthalmologist as part of the multidisciplinary team especially in patients with underlying metabolic syndrome or known ocular problems. It is equally imperative that emphasis is placed on patient education as well to reduce the risk of ophthalmic complications that could arise due to lack of compliance to follow-up or non-adherence to vitamin supplementation following surgery.
