摘　　要：目的探讨超声生物显微镜(UBM)下前房结构参数与原发性闭角型青光眼(PACG)合并白内障患者最佳矫正视力(BCVA)的相关性。方法选取2019年1月至2021年3月于本院确诊的80例白内障患者作为研究对象,根据入院检查结果分为PACG组(n=30)和无PACG组(n=50),使用天津迈达MD-300LUBM检查两组中央前房深度(ACD)、房角开放距离500(AOD_(500))、小梁睫状体距离(TCPD)、小梁虹膜夹角(TIA)、虹膜厚度(IT)、虹膜悬韧带距离(IZD)、虹膜晶状体夹角、巩膜睫状体夹角,采用非接触式眼压计检测两组眼压(IOP),采用糖尿病视网膜病变早期治疗研究(ETDRS)视力表检查两组BCVA水平。结果PACG组ACD浅于无PACG组,AOD_(500)、TCPD、TIA、IZD、虹膜晶状体夹角、巩膜睫状体夹角均小于无PACG组,IT(IT1、IT2、IT3)薄于无PACG组,差异有统计学意义(P<0.05)。PACG组IOP明显高于无PACG组,BCVA明显低于无PACG组,差异有统计学意义(P<0.05);Pearson相关分析结果显示,ACD、AOD_(500)、TCPD、TIA、IT、IZD、虹膜晶状体夹角、巩膜睫状体夹角与BCVA呈正相关(r>0,P<0.05)。结论UBM下前房结构参数与PACG合并白内障患者的BCVA呈正相关,临床可根据前房结构参数的变化评估患者的视力状况。Objective To explore the correlation between anterior chamber structure parameters and best corrected visual acuity(BCVA)in patients with primary angle-closed glaucoma(PACG)and cataract under ultrasonic biological microscope(UBM).Methods A total of 80 patients with cataract confirmed in our hospital from January 2019 to March 2021 were enrolled as the research subjects,they were divided into PACG group(n=30)and non-PACG group(n=50)according to examination results after admission.The anterior chamber depth(ACD),angle opening distance 500(AOD_(500)),meshwork ciliary process distance(TCPD),trabecular iris angle(TIA),iris thickness(IT),distance of iris suspensory ligament(IZD),irislens angle and sclera-ciliary body angle in both groups were examined by Tianjin Maida MD-300L UBM,the intraocular pressure(IOP)was measured by non-contact tonometer,BCVA was detected by early treatment diabetic retinopathy study(ETDRS)eye chart.Results The ACD of the PACG group was shallower than that of the non-PACG group,the AOD_(500),TCPD,TIA,IZD,iris-lens angle and sclera-ciliary body angle were all smaller than those of the non-PACG group,IT(IT1,IT2,IT3)was thinner than that of the non-PACG group,and the differences were statistically significant(P<0.05).IOP in PACG group was significantly higher than that in non-PACG group,while BCVA was significantly lower than that in non-PACG group,the difference was statistically significant(P<0.05).The results of Pearson correlation analysis showed that ACD,AOD_(500),TCPD,TIA,IT,IZD,iris-lens angle and sclera-ciliary body angle were positively correlated with BCVA(P<0.05).Conclusion The anterior chamber struc-ture parameters are positively correlated with BCVA in patients with PACG and cataract under UBM,Clinically,visual acuity of patients can be evaluated according to the changes of anterior chamber structure parameters.
