Bariatric Surgery No Guarantee Against Worsening Diabetic Retinopathy
Bariatric surgery does not prevent progression of diabetic retinopathy (DR), according to findings from a new observational study published by Medscape.
“All diabetic patients should attend regular DR screening post bariatric surgery to allow early detection of potentially sight-threatening changes, particularly among those with identifiable risk factors,” Dr. Yunzi Chen of Sunderland Eye Infirmary in Sunderland, UK, and colleagues state in their report, published in Eye, online July 21.
Bariatric surgery leads to better glycemic control for patients with type 2 diabetes, with 80% achieving remission within two years, Dr. Chen and colleagues note. But studies of the effect of weight-loss surgery in microvascular complications such as DR have had mixed results.
