目的 :探讨眼内硅油取出术后视网膜再脱离情况。方法 :6 8例视网膜脱离患者于 1998年 1月至 2 0 0 0年 12月手术 ,并于 3～ 10个月后取出硅油 ,术后对其严密随诊。结果 :6 8例患者中于取出硅油后有 18例视网膜再脱离 :4例 (16 7% )于术后 2周 ,4例 (5 0 % )于术后 2～ 4周 ;3例 (16 7% )于术后 4～ 8周 ;2例 (11% )于术后 8～ 15周。结论 :视网膜再脱离发生率随硅油取出后时间而减少。视网膜再脱离的原因为 (1)视网膜孔被忽视或未完全封闭 ;(2 )PVR ;(3)新的视网膜孔 ;(4 )医源性视网膜孔。这些患者应于术后严密随诊至少 4个月
Objective: To investigate the retinal reattachment after removal of intraocular silicone oil. Methods: Sixty-eight retinal detachment patients underwent surgery from January 1998 to December 2000. Silicone oil was removed after 3 to 10 months and was closely followed up. RESULTS: Eighteen cases of retinal detachment were found in 68 patients after removal of the silicone oil: 4 (16.7%) at 2 weeks, 4 (50%) at 2 to 4 weeks and 3 (16 7%) at 4 to 8 weeks postoperatively; 2 (11%) at 8 to 15 weeks postoperatively. Conclusion: The incidence of retinal reattachment decreased with time after silicone oil was removed. Retinal detachment due to (1) the retinal hole was overlooked or not completely closed; (2) PVR; (3) a new retinal hole; (4) iatrogenic retinal holes. These patients should be closely followed up for at least 4 months after surgery
