Thickening of inner retinal layers in the parafovea after bariatric surgery in patients with type 2 diabetes

Abstract

Patients with T2D had thickening of the retina after gastric bypass surgery with a peak 6 months postoperatively. The thickening was most pronounced in the retinal nerve fibre layer and the outer nuclear layer of the parafovea. In multivariate analysis, the central retinal artery equivalent increased at 12 months.
