作者使用小功率CO_2激光装置对13例13眼视网膜脱离行视网膜下液排除术,效果确实且无常规方法排液的并发症。手术操作:热凝预定切开部位,于巩膜后切开约2mm长,暴露脉络膜,做巩膜厚度2/3深度的预置缝线,将CO_2激光器发出的描准光束垂直并聚焦于暴露的脉络膜面上。照射条件:输出功率2～3W,光斑80μm,时间0.05秒。几乎所有病例一经照射均可充分排出视网膜下液。眼底检查如果发现排液不充分时,可轻压巩膜促使液体排出,确认充分排出后,结扎预置缝线。讨论:(一) 常规方法排液的主要合并症:
The authors used a low-power CO_2 laser device on 13 cases of retinal detachment of 13 cases of subretinal fluid exclusion, the effect is true and no complications of conventional drainage method. Surgical Procedure: The site of thermal coagulation was cut to about 2 mm long after the sclera, exposing the choroid and presetting the suture to a depth of 2/3 of the scleral thickness. The standard beam emitted by the CO 2 laser was perpendicular and focused on the exposed choroid Face. Irradiation conditions: output power 2 ~ 3W, spot 80μm, time 0.05 seconds. Almost all cases of irradiation can be fully discharged subretinal fluid. Fundus examination If you find that the drainage is not sufficient, you can gently pressure sclera to promote liquid discharge, to confirm the full discharge, ligation preset suture. Discussion: (a) the main method of drainage of the conventional complications:
