【摘要】 目的 分析后房型人工晶体缝线固定术后视网膜脱离的临床特征。方法 观察后房型人工晶体缝线固定术后视网膜脱离14例14眼的患者背景、术中所见及术后观察。结果 患者术后视网膜脱离发生在20～204天（平均96.5天），初次手术6眼施行了巩膜环扎术，8眼玻璃体手术。经玻璃体手术者视网膜全部解剖复位，3眼巩膜外手术复位失败，后经玻璃体手术网膜复位。视网膜脱离发生的原因是睫状沟缝合时医源性裂孔3眼，前部玻璃体牵拉性网膜裂孔11眼。术后视力提高者5眼，不变者6眼，3眼视力下降。结论 后房型人工晶体缝线固定术后前部玻璃体的牵拉是视网膜脱离的主要原因，玻璃体手术是有效的。另外，由于血—眼屏障的破坏易发生前部增生性玻璃体病变，早期的玻璃体手术是重要的。

Cause analysis of retinal detachment following suture fixation of posterior chamber intraocular lens implantation
【Abstract】 Objective To report clinical characteristic on the retinal detachment following suture fixation of posterior chamber intraocular lens implantation.Methods We retrospectively reviewed the records of 14 patients (14 eyes),and analyzed background factors,intraoperative findings and surgical outcomes.Results Retinal detachment occurred from 20 to 204 days (mean 96.5 days) after suture fixation of posterior chamber intraocular lens implantation.Retinal detachment developed due to perforation of the retina by the fixation needle in 3 eyes,and due to formation of retinal tears with vitreous traction in 11 eyes.Primary vitrectomy was performed in 8 eyes and scleral buckling in 6 eyes.Retinal reattachment was achieved in all eyes that underwent vitrectomy,however both eyes that underwent scleral buckling developed proliferative vitrectomy postoperatively necessitating subsequent vitreous surgery.Postoperative visual acuities improved more than 5 eyes,remained unchanged in 6 eyes,and worsened more than 3 eyes.Conclusion Primary vitrectomy appeared to be effective in treating retinal detachment following suture fixation of posterior chamber intraocular lens implantation,because most of our cases were associated with strong vitreous traction.Such retinal detachments should be immediately treated due to the higher risk of developing proliferative vitreoretinopathy with breakdown of the blood-retinal barrier.
