摘要:

目的:探究玻璃体切除联合硅油填充术后视力下降的发生率及其影响因素。方法:回顾性分析2017年至2020年在我院接受23G玻璃体切除术联合眼内填充硅油的132例患者(132眼)的临床资料,根据有无视力下降将其分为视力下降组和无视力下降组,对比两组术前临床特征、术后临床指标,并采用Logistic多元逐步回归法分析影响视力下降的主要因素。结果:玻璃体切除联合硅油填充术后视力下降的发生率为20.5%,Logistic多元逐步回归分析显示影响视力下降的主要因素为硅油填塞持续时间、硅油填塞期间最大眼内压和眼内压增高发生时间(P<0.05)。结论:适当减少眼内硅油填充时长,控制硅油填充术时患者的眼压,有利于减少玻璃体切除联合硅油填充术后不明原因视力下降的发生。

Objective:To investigate the incidence and influencing factors of visual loss after vitrectomy surgery with silicon oil tamponade. Methods:One hundred and thirty-two patients who received 23G vitrectomy combined with intraocular silicon oil tamponade from 2017 to 2020 were retrospectively analyzed. The patients were divided into two groups based on the vision loss or not. The pre- and post-operative clinical characteristics of the two groups were compared, and the main factors affecting visual loss were analyzed by Logistic multiple stepwise regression method. Results:The incidence of visual loss after vitrectomy surgery with silicon oil tamponade was 20.5%. Logistic multiple stepwise regression analysis showed that the main factors influencing the visual loss were the duration of silicone oil tamponade, the maximum intraocular pressure during silicone oil tamponade and the time point of intraocular pressure increased(P<0.05). Conclusion:The control of intraocular pressure after silicone oil filling and timely reduction of intraocular filling time are helpful to reduce the occurrence of unknown visual loss after operation.
