Intravitreal triamcinolone acetonide for macular edema in retinal vein occlusion / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

AIM:To compare the efficacy of intravitreal triamcino-lone acetonide and conventional treatment for macular edema in retinal vein occlusion.METHODS:In this clinical study 21 patients were enrolled with macular edema due to retinal vein occlu-sion. Prior to treatment, all patients underwent an exten-sive ophthalmic examination. Patients were divided randomly into two groups. Nine patients were treated with 4mg intravitreal triamcinolone acetonide (Kenalog) and 12 patients underwent conventional treatment.RESULTS: Before treatment, logMAR (logarithm minimum angle resolution) visual acuity in conventional treatment was 1.20±0.38 and in Kenalog group it was 1.64±0.31. One month after treatment, the visual acuity was improved to 0.98±0.54 in conventional treatment group and 0.87±0.61 in Kenalog group. There was a significant difference in visual acuity improvement between conventional treatment group and Kenalog group (0.22 vs 0.76) (P=0.01).CONCLUSION:Our results showed that although visual acuity improvement was seen in both groups but Kenalog was more effective than conventional treatment in macular edema due to retinal vein occlusion.
