Posterior Sub-Tenon's Injection of Triamcinolone in the Treatment of CME Associated With Retinal Vein Occlusion

Abstract

Abstract: : Purpose:To investigate the efficacy of posterior sub-Tenon’s injection of triamcinolone in the treatment of cystoid macular edema (CME) associated with retinal vein occlusion. Methods: Five eyes of 5 patients (4 men and 1 woman; age ranged from 50 through 71 years old) who were diagnosed with CME were given sub-Tenon’s injectoins of triamcinolone (10 mg). The central macular thickness measured by optical coherence tomography (OCT) and visual acuities were analyzed during prospective follow up. Results: The average decrease of central macular thickness of 5 eyes was 75.7% after 1 month, 68.9% after 2 months, while the central macular thickness began to increase after 3 months. After 2 months , the improvement of visual acuity (≥2 Snellen lines) was seen in 2 eyes (40%) with posterior vitreous detachment (PVD). In 1 eye, remarkable improvement was obtained to 20/20 from 20/50. Visual acuity did not improved in 3 eyes without PVD, while the retinal thickness decreased. Conclusions: Posterior sub-Tenon’s injection of triamcinolone could be effective in the treatment of CME associated with retinal vein occlusion.
