硅油取出术后视力丧失原因分析

Analysis of the causes of visual loss after silicone oil removal

目的 探讨硅油取出术后患者视力丧失的原因。 方法 对行硅油取出术后最终视力丧失的１５ 例患者的１５ 只眼临床及随访资料进行分析，随访时间４～２０个月。 结果 １５只眼中，视网膜再脱离１１只眼，其中５只眼由于各种原因不再手术而失明；６只眼为再次手术失败，视网膜再脱离而失明。因继发性青光眼和角膜混浊而丧失视力者各２ 只眼。 结论 取出硅油后最终丧失视力的原因最常见为视网膜再脱离，其次为继发性青光眼及角膜混浊。

Objective To investigate the causes of visual loss and failure of treatment after intraocular silicone oil removal. Methods Retrospective clinical analysis of the causes of loss of visual acuity of 15 eyes after silicone oil removal in patients with complicated retinal detachment which were successfully treated with vitreous and retinal microsurgery. Results Among the 15 eyes,retina failed to reattach in 11 eyes,secondary glaucoma occurred in 2 eyes and corneal opacity appeared in another two eyes.All of them were resulted in total loss of vision. Conclusion Retinal redetachment was the leading cause of final visual loss in the failing 15 cases(15 eyes) after intraocular silicone oil removal,and secondary glaucoma and corneal decompensation may also be the causes of visual loss.
