BACKGROUND
Cataract extraction is the most commonly performed surgery in the National Health Service. Myopia increases the risk of postoperative rhegmatogenous retinal detachment (RRD). The aim of this study was to determine the incidence and rate of RRD seven years after cataract extraction in highly myopic eyes.
METHODS
Retrospective review was performed of notes of all high myopes (axial length 26.0 mm or more) who underwent cataract extraction during the study period in one centre.
RESULTS
84 eyes met the study criteria. Follow-up time from surgery was 93 to 147 months (median 127 months). The average axial length was 28.72 mm (sd 1.37). Two eyes developed post-operative RRD; the incidence was 2.4% and the rate one RRD per 441.6 person-years. The results of 15 other studies on the incidence of RRD after cataract extraction in high myopia were pooled and combined with our estimate.
CONCLUSION
Both patients in our study who developed RRD had risk factors for this complication as well as high myopia. Risk factors are discussed in the light of our results and the pooled estimate. Our follow-up time is longer than most. Future case series should calculate rates to allow meaningful comparison of case series.
背景
白内障摘除术是英国国家医疗服务体系中最常开展的手术。近视会增加白内障摘除术后孔源性视网膜脱离（RRD）的风险。本研究旨在确定高度近视患者白内障摘除术后7年RRD的发生率和发病速率。
方法
对研究期间在一个中心接受白内障摘除术的所有高度近视患者（眼轴长度26.0mm及以上）的病历进行回顾性分析。
结果
84只眼符合研究标准。手术至随访的时间为93至147个月（中位数127个月）。平均眼轴长度为28.72mm（标准差1.37）。2只眼发生了术后RRD；发生率为2.4%，发病速率为每441.6人年发生1例RRD。汇总了其他15项关于高度近视患者白内障摘除术后RRD发生率的研究，并与我们的评估结果相结合。
结论
我们研究中发生RRD的两名患者除高度近视外，还有该并发症的危险因素。根据我们的结果和汇总评估对危险因素进行了讨论。我们的随访时间比大多数研究更长。未来的病例系列应计算发病速率，以便对病例系列进行有意义的比较。
