Abstract： 目的 探讨外伤眼玻璃体切割术后结局和视力预后的相关因素.方法 137只经玻璃体切割手术外伤眼,按自然存在因素和围手术因素录入EPIINFO软件并转入SAS分析系统中分析.结果 手术成功104只眼(75.9%),手术失败33只眼(24.1%).最终视力小于0.02的63只眼(45.9%),大于或等于0.02的74只眼(54.1%).多元回归结果显示:在伤眼自然因素中视网膜脱离发生对伤眼手术失败结局影响具有显著性意义(RR=3.0 P=0.020);对伤眼不良视力预后影响具有显著性意义(RR=3.2 P=0.001).外伤-手术时间延长,手术失败的危险性增加(RR=1.0,P=0.007).在围手术因素中,手术复杂程度增加,手术失败的危险性随之增加(RR=2.4 P=0.000);对不良视力预后危险性也增加(RR=2.2 P=0.002).有术后并发症比无并发症发生手术失败的危险性高7.5倍(RR=7.5 P=0.000);对不良视力预后的危险性高3.1倍(RR=3.1 P=0.022).结论 伤眼视网膜脱离发生、手术复杂程度及术后并发症发生是伤眼手术后不良结局和视力不良预后的重要危险因素.
