玻璃体切除联合重硅油填充治疗下方PVR视网膜脱离

目的探讨玻璃体切除联合重硅油眼内填充治疗下方严重PVR视网膜脱离的效果。方法对26例（26眼）诊断为合并下方PVR视网膜脱离者行玻璃体切除联合眼内重硅油填充，并同时随机抽取26眼患相似类型的视网膜脱离者，在玻璃体切除术后给予眼内硅油填充作为对照治疗。术后随访7～12月，观察其视网膜复位、视力、眼压及硅油乳化等情况。结果重硅油组视网膜一次性完全复位者24眼，占92．30％，硅油组一次性视网膜完全复位者18眼，占69．23％，（P〈0．05）。视网膜完全复位者绝大部分视力有不同程度提高。所有患者均未见明显炎症反应。结论玻璃体切除联合重硅油眼内填充是治疗下方PVR视网膜脱离的有效方法，可以降低术后视网膜脱离的复发率。

The treatment of vitrectomy with tamponade of heavy silicone oil for retinal detachment combined with infeHor PVR

Objective To explore the effect of vitrectomy with tamponade of heavy silicone oil for retinal detachment combined with inferior PVR. Methods 26 patients （26 eyes） diagnosed as retinal detachment with inferior PVR underwent vitrectomy combined with tamponade of heavy silicone oil. While 26 eyes with the similar type of retinal detachment underwent vitrectomy combined with tamponade of silicone oil. All patients were changed at random. Afteroperatively, all cases were followed up for 7 to 12 months. Comparing the rate of retinal retachment, visual acuity, ocular pressure and emulsification between tow groups. Results At the end of follow up, the HSO group （26 eyes） achieved anatomical success in 24 eyes ,while the SO group（26 eyes）achieved anatomical success in 18eyes, the difference between tow groups is significant statistically（P 〈 0.05 ）. The acuity increased in most patients with retinal retachment. There was no severe inflammatory reaction in all patients. Conclusion Vitrectomy with tamponade of heavy silicone oil is effective for retinal detachment combined with inferior PVR. It can decrease the rate of redetachment of retinal detachment combined with inferior PVR after operation. Conclusion Heavy siliconeoil in vitrectomy is effective for PVR and retinal detachment.
