Background: Diabetic Retinopathy (DR) is a significant complication of diabetes mellitus, which can worsen during rapid fluctuations in glycaemic control. Bariatric surgery can cause sudden improvement in diabetes control which can affect DR in the short term.Objectives: To assess the immediate and late impact of bariatric surgery on DR status in patients with type 2 diabetes mellitus and to evaluate the need for continuing retinal screening despite improvement or remission of diabetes.
Methods:A retrospective clinical observational analysis was conducted on patients who underwent bariatric surgery for type 2 diabetes. One-year pre-operative and all post-operative retinal screen images were obtained and graded using the national diabetic eye screen programme grading.
Conclusion:Our study demonstrates the variable nature of progression of DR after bariatric surgery in patients with type 2 diabetes mellitus. Long term trials are needed to identify the pattern of progression and to identify risk factors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
