目的 分析硅油充填的时间与视网膜复位的关系及硅油在眼内存留时间和硅油并发症产生的关系。方法 回顾分析 83例 ( 83只眼 )行硅油取出术患者的临床资料及随访记录。结果 行硅油取出的时间为 3～ 13个月 ,平均 8个月。在无发生硅油相关的并发症的条件下 ,78例在取出硅油之后 ,视力无明显改变或稍有提高。角膜变性的病例 ,在硅油取出之后 ,其混浊情况无明显改变。 11例青光眼在硅油取出之后眼压恢复正常者 8例 ,5例在硅油取出之发生了复发性视网膜脱离。结论 硅油取出的最佳时机是 3～ 6个月。硅油取出可以缓解硅油并发症的发展。硅油取出术的并发症主要为复发性视网膜脱离、脉络膜出血、脉络膜脱离、视网膜出血及低眼压。
Objective To analyze the relationship between the filling time of silicone oil and retinal reattachment and the relationship between the silicone oil retention time in the eye and the complications of silicone oil. Methods The clinical data and follow-up records of 83 patients (83 eyes) undergoing silicone oil removal were retrospectively analyzed. Results of the line of silicone oil removed for 3 to 13 months, an average of 8 months. In the absence of silicone oil-related complications, 78 patients with no significant change in visual acuity or slight increase in silicone oil. Corneal degeneration cases, the silicone oil removed, the turbidity did not change significantly. Eleven patients with glaucoma recovered intraocular pressure after removal of silicone oil in 8 patients, and 5 patients underwent recurrent retinal detachment in silicone oil removal. Conclusion The best time to remove silicone oil is 3 to 6 months. Removal of silicone oil can ease the development of silicone oil complications. The main complications of silicone oil removal of recurrent retinal detachment, choroidal hemorrhage, choroidal detachment, retinal hemorrhage and hypotension.
