显微镜下视网膜脱离复位手术临床应用

External-route microsurgery for retinal detachment.

目的探讨显微镜下视网膜脱离复位手术的临床效果。方法孔源性视网膜脱离36例(36眼)由同一术者进行外路手术,均在术中应用手术显微镜进行裂孔定位。冷凝封闭及巩膜外垫压。定期观察术后视力、眼内反应和视网膜复位情况。结果经显微镜直视下外路手术患者,术后随访15d-167d,视网膜完全复位35眼(97.2%),视力较术前提高33只眼(91.7%),不变2只眼,下降1只眼。最好矫正视力0.3以上33只眼(91.7%)。术后所有患者视网膜冷凝反应Ⅰ-Ⅱ级,无Ⅲ-Ⅳ级。轻度屈光介质浑浊不影响手术过程。结论经手术显微镜直视下外路治疗孔源性视网膜脱离安全有效、简单可行,值得推广。

Objective To observe the clinical efficacy of external-route surgery of retinal detachment. Methods 36 patients （36 eyes） with rhegmatogenous retinal detachment underwent external-route surgery by the same doctor. Microscope was used to locate the hole in the surgery. The visual acuity, reaction and the reattachment of retina were observed after surgery. Results After 15 d -167 d, 35 of 36 eyes were repaired completely with the rate of 91.9%.Visual acuity were improved in 91.9% （33 of 36）of the total eyes. The corrected acuity was better than 0.3 in 33 eyes（91.7% ）. The reaction of retinal cryotherapy in all cases were at I-Ⅱ etinal cryotherapy and holes were not affected by mild opacity of the refractive media .Conclusin The external-route microsurgery is simple, convenient, reliable and effective in treating rhegmatogenous retinal detachment.
