We prospectively studied 120 eyes with intact opacified posterior capsules in 120 consecutive patients to determine the incidence of new late-onset angiographic cystoid macular edema (CME) after neodynium: yttrium aluminum garnet (Nd:YAG) laser posterior capsulotomy. Fifty-seven of 120 patients (48%) had both precapsulotomy and one-year post-capsulotomy angiograms done. Of these 57 patients, three eyes had angiographic CME before capsulotomy and two of these three cases had persistent CME one year after capsulotomy. In the other 54 patients, three new late-onset cases occurred (5.6%). Because the incidence of postcapsulotomy new CME was low, the statistical significance of possible risk factors, such as rupture of the anterior hyaloid face or pseudophakic status cannot be determined. However, aphakic patients with vitreous prolapse after capsulotomy tended to have a higher incidence to CME than pseudophakic patients. We recommend fluorescein angiography to identify occult CME in cases of unexplained visual-acuity decrease after capsulotomy.
我们前瞻性地研究了120例连续患者的120只后囊混浊完整的眼睛，以确定钕:钇铝石榴石（Nd:YAG）激光后囊切开术后新的迟发性血管造影性黄斑囊样水肿（CME）的发生率。120例患者中有57例（48%）进行了囊切开术前和囊切开术后一年的血管造影。在这57例患者中，3只眼在囊切开术前有血管造影性CME，其中2例在囊切开术后一年仍有持续性CME。在其他54例患者中，出现了3例新的迟发性病例（5.6%）。由于囊切开术后新CME的发生率较低，因此无法确定前玻璃体膜破裂或人工晶状体状态等可能危险因素的统计学意义。然而，囊切开术后玻璃体脱垂的无晶状体患者发生CME的发生率往往高于人工晶状体患者。我们建议在囊切开术后出现无法解释的视力下降时，进行荧光素血管造影以识别隐匿性CME。
