摘　　要：目的:探究高频超声生物显微镜(UBM)对白内障合并原发性闭角型青光眼(PACG)术前晶状体悬韧带及术后房角形态的观察。方法:选取2016年1月至2019年12月在本院拟行白内障手术的且晶状体悬韧带及术后房角形态情况不明的白内障合并PACG患者50例(50眼)为研究对象。术前患者均行UBM检查,观察并记录患者晶状体悬韧带异常情况及术后房角形态,评估UBM检查的准确性。结果:UBM检查显示,50例白内障联合PAGG患者中,悬韧带异常者为29眼(58%),其中悬韧带异常者中,离断者9眼(18%),松弛20眼(40%)。手术结果显示,50例白内障联合PAGG患者中,悬韧带异常者为27眼(54%),其中悬韧带异常者中,离断者8眼(16%),松弛19眼(38%)。两种检查方式差异无统计学意义,准确性较高。另UBM对患者房角定量化检测显示,术后患者房角的ACD、AOD500及TCPD值均有明显提高,差异具有统计学意义(P<0.05),而ID1的值手术前后差异无统计学意义(P>0.05)。结论:UBM可准确观察和定位晶状体悬韧带的异常情况,且对患者患眼房角形态的观察提供定量化检测依据,具有重要的临床意义。Objective:To investigate and observe the configuration of preoperative suspensory ligament of lens and postoperative chamber angle with low frequency ultrasound biological microscope(UBM)applied in surgery of cataract with primary angle-closure glaucoma(PACG).Methods:A total of 50 patients(50 eyes)with PACG and cataract and undefined configuration of preoperative suspensory ligament of lens and postoperative chamber angle who were prepared for cataract surgery from January 2016 to December 2019 were selected.Preoperative UBM examination was performed on all patients,and abnormalities of the lens suspensory ligament and postoperative chamber angle were observed and recorded to evaluate the accuracy of UBM examination.Results:UBM examination showed that among the 50 patients with cataract combined with PACG,29 eyes(58%)had abnormal suspensory ligament,9 eyes(18%)had detached suspensory ligament,and 20 eyes(40%)had loose ligament.Surgical results showed that 27 eyes(54%)of the 50 patients with cataract combined with PACG had abnormal suspensory ligament,among which 8 eyes(16%)had detached suspensory ligament,and 19 eyes(38%)had loose ligament.The difference between the two examination methods was not statistically significant and the accuracy was high.In addition,the quantitative detection of the patient's chamber angle by UBM showed that the postoperative ACD,AOD500 and TCPD of the patient's chamber angle were significantly increased,with statistically significant difference(P<0.05),while the difference of ID1 before and after surgery was not statistically significant(P>0.05).Conclusion:UBM can accurately observe and locate the abnormal situation of the lens suspensory ligament,and provide a quantitative basis for the observation of the shape of the angle of the affected eye,which is of great clinical significance.
