简介：目的探讨不同程度眼外伤前房积血的综合治疗。方法回顾性分析我院2007年1月至2010年10月收治的47例外伤性前房积血临床资料。结果Ⅰ级和Ⅱ级外伤性前房积血无再出血和其他并发症者恢复顺利,预后良好,Ⅲ级以上外伤性前房积血,或合并有再出血或其他并发症者恢复慢,预后不良。结论采取及时、合理的药物治疗,把握恰当的手术时机、选择正确的手术方法,促进积血吸收,防止再出血和并发症的发生是治疗的关键。

简介：目的探讨角膜隧道切口前房冲洗术治疗创伤性前房积血的疗效和临床价值。方法对我院自2005年1月至2010年6月收治27例严重创伤性前房积血患者行角膜隧道切口前房冲洗术。观察术中并发症,术后视力,眼压。结果27例均一次清除完前房积血,无术中并发症,术中虹膜无脱出。术后随访6月,矫正视力0.8以上者7例,0.3-0.8者16例,0.05-0.3有4例,23例低于21mmHg。结论角膜隧道切口前房冲洗术操作简单,手术损伤小,是安全有效的手术方法。
