Bariatric surgery may prevent new cases of diabetic retinopa
Patients with type 2 diabetes who underwent bariatric surgery were less likely to develop diabetic retinopathy vs. those treated medically, but whether bariatric surgery is associated with a regression of the condition remains unclear, according to a recent meta-analysis.

“With bariatric surgery, a new concept arose, that is [the] remission/resolution of type 2 diabetes,” Antonio E. Pontiroli, MD, of the department of health sciences at the University of Milan, and colleagues wrote. “Less studied is the possible role in the prevention of retinopathy; uncontrolled studies on consecutive patients undergoing bariatric surgery yielded conflicting results, suggesting that retinopathy could improve, deteriorate or be stable after bariatric surgery.”
