研究目的:

主要研究目的 探究视网膜复位术对脉络膜血流的影响及其机制,及不同手术方式(SB 及PPV 手术)对脉络膜血流影响的差异 次要研究目的 (1)探究视网膜脱离复位术对视网膜血流的影响 (2)探究视网膜脱离复位术后脉络膜血流的变化与术后视力预后的相关性 (3)探究巩膜扣带术对前房参数的影响及其与 IOP的升高之间的相关性 (4)探究巩膜扣带术对虹膜血流的影响  

Objectives of Study:

Primary Research Objective: To investigate the effects and mechanisms of retinal reattachment surgery on choroidal blood flow, and the differences in choroidal blood flow caused by different surgical methods (SB and PPV surgeries). Secondary Research Objectives: (1) To investigate the effects of retinal detachment reattachment surgery on retinal blood flow. (2) To explore the correlation between changes in choroidal blood flow after retinal detachment reattachment surgery and postoperative visual prognosis. (3) To investigate the effects of scleral buckle surgery on anterior chamber parameters and their correlation with increased intraocular pressure (IOP). (4) To investigate the effects of scleral buckle surgery on iris blood flow.
