硅油填充术后青光眼及房角变化

Glaucoma and anterior chamber angle changes after intravitreal silicone oil injection for complicated retinal detachment

目的 评估硅油填充术后青光眼及房角变化。 方法 对 33例 34只眼行硅油填充术的患者的眼压和房角进行前瞻性研究。 结果 硅油注入术后 9只眼发生了青光眼 ,占 2 6 % ,直接由硅油引起的有7只眼 ,占 78% (7/ 9) ;1～ 4.5个月上方房角变化 :11只眼不同程度虹膜周边前粘连 ,2 2只眼有硅油乳化小滴 ;下方虹膜周边切除孔闭锁的 7只眼中有 6只眼发生了青光眼 (P<0 .0 5 )。 结论 硅油填充术后青光眼发生率高 ,虹膜周边切除孔闭锁 ,硅油乳化是引起硅油术后青光眼的主要原因。

Objective To evaluate glaucoma and anterior chamber angle changes after intravitreal silicone oil injection(SOI). Methods The intraocular pressure(IOP) and anterior chamber angles of 34 eyes(33 patients)undergone pars plana vitrectomy and SOI were observed. Results Glaucoma occurred in 9 eyes(26%),in which silicone oil glaucoma(SOG)accounted for 77%(7/9).The changes of the superior part of anterior chamber angle were peripheral anterior synechiae in 11 eye(32%) and SO emulsification droplets in 22 eyes(64%) in 1～4.5 months after surgeries.Glaucoma occurred in 6 eyes of 7 eyes undergone peripheral iridectomy at the inferior part of the iris after the closure of iridectomy holes(P<0.05). Conclusion High incidence of glaucoma was found in this series of patients after intravitreal silicone oil injection,and the main causes of SOG were closure of the inferior iridecomy hole and silicone emulsification.
