Abstract：
OBJECTIVE: To clarify the postoperative incidence of macular edema in patients undergoing surgery to repair rhegmatogenous retinal detachment and identify the associated risk factors.
METHODS: In this prospective, observational study, 79 patients who underwent surgery to correct rhegmatogenous retinal detachment using pars plana vitrectomy with silicone oil injection were analyzed. Patients were followed up postoperatively at 7, 30, 90, 180, and 365 days. At each visit, optical coherence tomography was performed to assess the presence or absence of macular edema. were analyzed as possible risk factors for macular edema: age, sex, macular status (attached or detached), presence of vitreoretinal proliferation, history of previous intraocular surgery, reported time of symptoms suggestive of rhegmatogenous retinal detachment up to the date of surgery, and the surgical modality performed.
RESULTS: The 1-year macular edema prevalence rate was 26.6%. In the adjusted analysis, older patients had a higher risk of macular edema, and each 1-year increase in age increased the risk of macular edema by 6% (95% confidence interval = 1.00-1.12). The macular status, vitreoretinal proliferation, the surgical technique used, prior intraocular surgery, and the intraocular lens status were not identified as risk factors. However, the incidence of macular edema increased up to 180 days after surgery, peaking at 10.6%, and then decreased until 365 days after surgery.
CONCLUSIONS: Macular edema was a common complication after surgery to treat rhegmatogenous retinal detachment, with its incidence peaking between 30 and 180 days after surgery. Age was an important risk factor for macular edema in this cohort.

摘要：
目的：了解孔源性视网膜脱离手术患者术后黄斑水肿的发生率及相关危险因素。
方法：在此前瞻性中，观察性研究，分析了79例接受手术治疗以矫正孔源性视网膜脱离的患者。术后随访7、30、90、180和365天。每次访问,我们进行了光学相干断层扫描以评估黄斑水肿的存在与否.分析了黄斑水肿的可能危险因素：年龄，性别,黄斑状态（连接或分离），玻璃体视网膜增生的存在，既往眼内手术史，报告的症状时间暗示到手术日期的孔源性视网膜脱离，和手术方式。
结果：1年黄斑水肿患病率为26.6%。在调整后的分析中，老年患者黄斑水肿的风险较高，年龄每增加1年,黄斑水肿风险增加6%(95%置信区间=1.00-1.12).黄斑状态，玻璃体视网膜增生,使用的手术技术，先前的眼内手术，而人工晶状体状态未被确定为危险因素.然而,黄斑水肿的发生率增加到手术后180天，峰值为10.6%，然后下降到手术后365天。
结论：黄斑水肿是治疗孔源性视网膜脱离术后常见的并发症，其发病率在手术后30至180天达到峰值。年龄是该队列中黄斑水肿的重要危险因素。
