Abstract

PURPOSE: To compare the effect of triamcinolone acetonide injection between intravitreal injection alone group and intravitreal injection in combintaion with posterior subtenon injection group in diabetic macular edema.
METHODS
Twenty-nine eyes of 29 patients with diabetic macular edema were randomly classified into two groups. Intravitreal injection of triamcinolone acetonide 4 mg was administered to 15 eyes and posterior subtenon injection of triamcinolone acetonide 20 mg in combination with intravitreal injection was administered to 14 eyes. Best corrected visual acuity (BCVA), macular thickness measured by optical coherence tomography were assessed 1, 3, 6, and 12 months after the procedure.
RESULTS
Baseline BCVA and macular thickness showed no differences between two groups. BCVA and macular thickness 1, 3, and 6 months after the procedure revealed significant improvement, but no significant differences between two groups were observed.
CONCLUSIONS
Intravitreal injection of triamcinolone acetonide alone and intravitreal inejction in combination with posterior subtenon injection were equally effective, but had no significant differences.
