曲安奈德治疗视网膜分支静脉阻塞继发黄斑水肿的疗效评估

Objective To observe the therapeutic efficacy of intravitreal injection of triamcinolone aeetonide (IVTA) for maeular edema secondary to B RVO determined by optic coherence tomography (OCT)and multifoeal electroretinogram (mfERG). Methods TA was injected intravitreally in 28 eyes of 28 patients with maeular edema secondary to BRVO determined by OCT and mfERG. The change of visual acuity,the maeular thickness measured by OCT and maeular function by rnIERG were recorded and analyzed. Results Vi-sual acuity was improved significantly at the end of the follow up. The average macular thickness and the aver-age P1 amplitude was improved after treatment, which had statistical significance (P <0.05). Conelusion Ⅳ-TA could alleviate the macular edema secondary to BRVO. OCT and mfERG were useful means to evaluate the macular changes before and after IVTA for BRVO.
