We performed a prospective study evaluating the incidence of angiographic cystoid macular edema (CME) following extracapsular cataract extraction and posterior chamber intraocular lens implantation. Of the 162 eyes in the study, 141 were randomized into either a primary capsulotomy or a capsule intact group. The remaining eyes were not randomized due to intraoperative surgical complications, but they were included in the follow-up studies. Six weeks after surgery, angiographic CME was documented in 24% of the capsulotomy group and in 16% of the capsule intact group. The differences were not statistically significant. Including nonrandomized cases reduced the overall incidence of angiographic CME and the difference between the two groups. Angiographic CME was usually not extensive, and it was associated with a visual acuity less than 20/40 in 2.5% of eyes six weeks postoperatively. A subgroup of 120 eyes was followed up for approximately six months, when angiographic CME was present in 4% of the capsulotomy and capsule intact groups.
我们进行了一项前瞻性研究，评估囊外白内障摘除及后房型人工晶状体植入术后血管造影性黄斑囊样水肿（CME）的发生率。在该研究的162只眼中，141只被随机分为一期囊切开术组或完整囊膜组。其余的眼睛因术中手术并发症未被随机分组，但被纳入随访研究。术后六周，囊切开术组中24%的眼睛记录到血管造影性CME，完整囊膜组中这一比例为16%。差异无统计学意义。纳入非随机分组病例降低了血管造影性CME的总体发生率以及两组之间的差异。血管造影性CME通常范围不广泛，术后六周时，2.5%的眼睛视力低于20/40与之相关。对120只眼的亚组进行了约六个月的随访，此时囊切开术组和完整囊膜组中4%的眼睛存在血管造影性CME。
