方法：本研究为回顾性病例研究，对26例26眼行硅油填充术后早期(<15d)出现视网膜脱离的患者行巩膜外环扎及局部加压术。术后随访6～18mo，观察患者视网膜复位、视力及眼压情况。

结果：患者26例26眼均存在下方视网膜脱离； 22例22眼术后视网膜解剖复位，4例4眼再次行硅油注入术； 术后视力提高者22例22眼，视力不变者3例3眼，视力下降者1例1眼； 环扎术后早期存在眼压升高现象，观察至3mo眼压恢复正常。

结论：巩膜外环扎术是治疗硅油填充眼早期视网膜脱离的有效手段。

METHODS: This retrospective observation included 26 cases(26 eyes)who had the signs of early retinal detachment after the silicone oil tamponaded under 15 days. All the cases received scleral buckling and were observed with the change of retinal reattachment, visual acuity and intraocular pressure(IOP)for 6-18 months.

RESULTS: All 26 cases(26 eyes)had the retinal detachment at the inferior side. The retina of 22 cases(22 eyes)was anatomical attached(92%)after the operation and 4 cases(4 eyes)accepted another time of silicone oil tamponaded. The visual acuity improved in 22 cases(22 eyes), 3 cases(3 eyes)had no change and 1 case(1 eye)decreased. The IOP increased at early period after the operation and became normal after 3 months.

CONCLUSION: Scleral buckling is effective for the early retinal detachment eyes with silicone oil tamponaded.
