简介:目的:探讨激光周边虹膜成形术(laserperipheraliridoplasty,LPIP)治疗急性闭角型青光眼(acuteangle-closureglaucoma,AACG)急性发作期药物不能控制的高眼压持续状态中的疗效。方法:原发性急性闭角型青光眼67例69眼发作期药物治疗3~6h后眼压仍〉30mmHg时,行LPIP治疗。监测术前和术后30,60min和2h眼压、视力变化。应用UBM测量术前、术后2h房角宽度和虹膜厚度,并应用房角镜观察前房角粘连情况。结果:LPIP后2h,房角开放距离(AOD)较术前明显增大(P〈0.01),小梁虹膜夹角(TIA)增宽、部分患者周边虹膜前粘连(PAS)减少、周边虹膜变薄。所有患者眼压在激光虹膜成形术后不同时间均有不同程度下降。术前平均眼压53.81±10.22mmHg,术后30min平均眼压33.81±9.22mmHg,术后60min为21.93±7.19mmHg,2h后眼压下降至15.16±3.07mmHg,治疗前后差异有显著统计学意义(F=151.79,P〈0.01)。同时所有患者视力都有所提高。结论:LPIP可以明显加深患者的周边前房,增宽房角入口,降低患者眼压,是治疗AACG急性发作期药物不能控制高眼压持续状态的重要辅助措施,为青光眼的进一步治疗创造了条件,并且能够改善预后。

简介:目的探讨玻璃体腔注射雷珠单抗辅助23G玻璃体切割治疗增殖期糖尿病视网膜病变的优质护理。方法通过对28例28眼采用玻璃体腔注射雷珠单抗辅助玻璃体切割治疗糖尿病患者并发视网膜增殖期病变存在的主要护理问题,针对患者治疗各阶段,责任护士提供全程、连续、系统的优质护理服务,加强护患沟通,提高护理质量,缩短手术时间,减少并发症的发生。结果24眼一次性手术复位成功(85.7%)术后三个月取出硅油,其中有4例伴有晶状体混浊的同时行晶状体超声乳化联合人工晶体植入术;4例硅油填充下仍然存在下方局限性视网膜增殖,术后三个月取出硅油再次切割增殖膜然后注入C3F8气体填充,随访至气体完全吸收,视网膜复位。结论对玻璃体腔注射雷珠单抗辅助23G玻璃体切割治疗增殖期糖尿病视网膜病变的患者提供优质护理,可缩短手术时间,减少并发症的发生,提高病人及家属的满意度,提升患者的康复效果,是手术取得成功的关键因素。
