Abstract. Purpose:To report the outcome of sub-tenon injection of triamcinolone acetonide for diabetic macular edema. Cases and Method:This retrospective study was made on 9 eyes of 6 patients who received a single injection of 20mg triamcinolone acetonide for diabetic macular edema. Their age averaged 65 years. They were followed up for 5 to 11 months, average 8 months. Visual acuity was evaluated by logMAR. Changes by 0.2 were judged as improvement or deterioration. Results:Visual acuity improved in 4 eyes, remained unchanged in 5, and deteriorated in none. Out of 4 eyes with improvement, visual acuity returned to the initial level after 284 days. As major complications, ocular hypertension developed in one eye and blepharoptosis in two. Conclusion:Sub-tenon injection of triamcinolone acetonide may result in improved visual acuity in eyes with diabetic macular edema. Patients have to be informed beforehand regarding possible complications including ocular hypertension and blepharoptosis.
