目的 探讨间接检眼镜激光在玻璃体切割术中应用的方法和疗效。方法 对 76例 78只眼行玻璃体切割手术 ,术中应用间接检眼镜激光对视网膜进行光凝 ,光凝的范围是中周部以前的视网膜 ,重点是视网膜裂孔缘周围的视网膜、视网膜新生血管膜及视网膜无灌注区。曝光时间 10 0ms,输出功率为 2 40～ 6 5 0mW ,在裂孔缘视网膜及新生血管膜上形成Ⅲ级光斑 ,视网膜无灌注区形成Ⅰ～Ⅱ级光斑。结果 未脱离的视网膜及脱离的视网膜在重水或硅油充填复位的条件下顺利地进行了间接检眼镜激光光凝。术后 2周内对其中的 19例 2 2只眼行眼底荧光造影 (FFA)检查 ,13例需补充光凝。术后 1月复查 ,光斑色素增生 ,视网膜裂孔封闭好 ,术后 3个月复查FFA ,2 1只眼视网膜无灌注区和新生血管消失。结论 间接检眼镜激光在玻璃体切割术中的应用几乎能达到眼内激光相同的疗效。
Objective To explore the method and curative effect of indirect ophthalmoscope laser in vitrectomy. Methods Seventy-six eyes (78 eyes) underwent vitrectomy. During the operation, indirect ophthalmoscopic laser was used to photocoagulate the retina. The range of photocoagulation was the retina in the middle part of the periphery. The focus was on the retina around the retinal rim, the retinal neovascularization And no retinal perfusion area. Exposure time 10 0ms, the output power of 240 ~ 6500mW, in the retinal rim and retinal neovascularization film formation of grade III spot, no retinal perfusion area formation Ⅰ ~ Ⅱ spot. The results of non-detachment of the retina and the detachment of the retina in heavy water or silicone oil filled under the conditions of reset successfully ophthalmoscopic laser photocoagulation. Within 2 weeks after surgery, 19 eyes (22 eyes) underwent fundus fluorescein angiography (FFA), and 13 patients needed photocoagulation. One month after operation, pigmentation hyperplasia and retinal hiatus were closed, FFA was reexamined 3 months after operation, and no retinal perfusion and neovascularization disappeared in 21 eyes. Conclusion The application of indirect ophthalmoscope laser in vitrectomy can achieve the same effect of laser in the eye.
