目的：观察25G辅助巩膜外加压术治疗硅油眼视网膜脱离的疗效。

方法：回顾性分析硅油填充术后出现视网膜脱离的患者15例15眼行25G辅助直视下巩膜外加压术后3～6mo患者的视网膜复位、最佳矫正视力(best corrected visual acuity，BCVA)及眼压情况。

结果：术前患者15 例15眼均存在3：00～9：00位范围内的视网膜脱离； 术后视网膜解剖复位13例13眼，未复位2 例2眼。术后1mo最佳矫正视力提高1行以上者11例11眼，视力变化1行以内者3例3眼，视力下降1行以上者1例1眼。术后早期部分患者存在眼压升高现象，药物控制后可恢复正常。

结论：25G辅助直视下巩膜外加压术治疗硅油眼视网膜脱离疗效确切。

METHODS: In the retrospective case study, 15 eyes of 15 patients who had retinal detachment after silicone oil filling were treated with 25G-assisted scleral buckling under direct vision. Experimental patients were followed up for 3-6mo to observe the retinal reattachment, visual acuity and intraocular pressure.

RESULTS: There were 15 eyes of 15 patients with inferior retinal detachment before operation. Retinal reattachment was achieved in 13 eyes(13 patients), and retina failed to be reattached in 2 eyes(2 patients)after operation. Furthermore, postoperative visual acuity was found to be improved more than one line in 11 eyes(11 patient), unchanged in 3 eyes(3 patients), and decreased more than one line in 1 eye(1 patient). Meanwhile, early postoperative intraocular pressure increased in some patients and returned to normal after drug control.

CONCLUSION: The 25G-assisted scleral buckling under direct vision has a definite curative effect in the treatment of retinal detachment in silicone oil-filled eyes.
