手术显微镜下视网膜脱离外路手术的临床观察

摘要

目的 观察手术显微镜直视下视网膜裂孔定位、冷凝在外路孔源性视网膜脱离手术中的临床疗效.方法 孔源性视网膜脱离24例(24只眼),手术前详细检查裂孔位置、大小及脱离范围; 术中通过牵拉眼肌使裂孔尽量处于最低位,采用手术显微镜直视下预置环扎带、外放液、视网膜裂孔定位、冷凝及垫压.结果视网膜完全复位23只眼,再次外路手术复位1只眼.视力提高20只眼,不变3只眼,下降1只眼.结论 牵拉眼肌使裂孔处于最低位在手术显微镜直视下行视网膜脱离手术具有视野清晰、裂孔定位准、操作简便、疗效可靠的优点.%Objective To observe the clinical efficacy of location and cryocoagulation of retinal holes by microscope in external retinal detachment surgery.Methods Twenty-four patients ( 24 eyes ) of rhegmatogenous retinal detachment, which were examined of location, size and scope of holes before surgery , were performed external route microsurgery.The eyeball was controlled and made the holes at their lowest levels by pulling eye muscles during an operation.Results Twenty-three cases got complete retinal reattachment.One eye got reattachment after an additional scleral buckling.The visual acuity was improved in twenty eyes, the same as that of preoperation in three eye, and lowered in one eyes.Conclusion It is simple, easy observable and located accurately to perform externalroute microsurgery for rhegmatogenous retinal detachment, and the effect is satisfactory.
