Effect of a single intraoperative sub-Tenon injection of triamcinolone acetonide on the progression of diabetic retinopathy and visual outcomes after cataract surgery

A posterior sub-Tenon injection of triamcinolone acetonide lowered the incidence of CME after cataract surgery in diabetic patients, improved visual recovery, and reduced the amount of CMT increase in the short term (≤1 month postoperatively). However, triamcinolone acetonide did not affect DR progression over the 6-month follow-up.
