目的:探讨晶状体超声乳化联合不同术式治疗原发性闭角型青光眼(primary angle closure glaucoma,PACG)合并白内障的疗效及其对并发症的影响。方法:回顾性分析海南医学院第二附属医院2020年1月至2021年12月收治的88例PAGG合并白内障患者...目的:探讨晶状体超声乳化联合不同术式治疗原发性闭角型青光眼(primary angle closure glaucoma,PACG)合并白内障的疗效及其对并发症的影响。方法:回顾性分析海南医学院第二附属医院2020年1月至2021年12月收治的88例PAGG合并白内障患者。行晶状体超声乳化(phacoemulsification,Phaco)联合房角分离术的患者为观察组(n=42);行Phaco联合小梁切除术的患者为对照组(n=46)。比较2组术前及术后6个月眼压、前房深度、前房角度变化及中文版视觉相关生存质量量表(the Chinese version Vision-Related Quality of Life Questionnaire-25,CVRQol-25)评分,并对2组进行疗效比较。结果:与术前相比,术后6个月2组眼压均显著降低(均P<0.05),前房深度和前房角度均显著增高(均P<0.05)。与对照组相比,观察组前房角度、前房深度均明显增大(均P<0.05);2组眼压对比差异无统计学意义(P>0.05)。观察组视力提高率为88.10%,稍高于对照组的78.26%,但差异无统计学意义(P>0.05)。观察组手术相关并发症发生率为9.52%,相比对照组的26.09%显著降低(P<0.05)。术后6个月,观察组CVRQoL-25评分显著高于对照组(P<0.05)。结论:Phaco联合房角分离术治疗PAGG合并白内障能有效降低眼压,改善视力,相比Phaco联合小梁切除术并发症较少,且能改善患者视觉相关的生存质量。展开更多
