摘要
目的应用超声生物显微镜测量并比较正常前房和浅前房人群在不同体位状态下眼房角结构参数的差异。方法选取于我院接受白内障术前检查的患者64例(共64只眼),根据周边前房深度分为正常前房组(周边前房深度>1/3角膜厚度)34只眼和浅前房组(周边前房深度≤1/3角膜厚度)30只眼。由两名经验丰富的超声医师使用水囊式超声生物显微镜分别采集患者卧位和坐位时上、下、鼻、颞4个方位的房角影像,测量不同体位状态下每个方位的房角开放度数(AA)和房角开放距离(AOD500),分析两名超声医师对两组患者测量结果的再现性;使用IOLMaster 700扫频生物测量仪测量前房深度(ACD)、晶状体厚度(LT)和眼轴长度(AL),比较两组上述参数的差异。结果两名超声医师对两组测量结果具有良好的再现性。两组患者从卧位变为坐位时,上方AA、AOD500变窄,下方AA、AOD500变宽,差异均有统计学意义(均P<0.001);鼻、颞侧AA、AOD500比较差异均无统计学意义。正常前房组与浅前房组修正后坐位上、下方AA比较差异均有统计学意义(P=0.048、0.044),修正后坐位上、下方AOD500比较差异均有统计学意义(P=0.046、0.031),修正后坐位鼻、颞侧AA、AOD500比较差异均无统计学意义。正常前房组与浅前房组ACD、LT比较,差异均有统计学意义(均P<0.05),两组AL比较差异无统计学意义。结论应用超声生物显微镜可对不同体位状态下眼房角结构参数进行测量,体位变化可影响房角开放程度,当卧位变为坐位时,浅前房人群房角变化程度大于正常前房人群。
Objective To measure and compare the differences in the structural parameters of the eye chamber angle between normal and shallow anterior chambers in different positions by ultrasound biomicroscopy.Methods Sixty-four patients(64 eyes)were selected for preoperative cataract examination in our hospital,they divided into two groups according to the peripheral anterior chamber depth:the normal group(>1/3 corneal thickness,34 eyes)and the shallow anterior chamber group(≤1/3 corneal thickness,30 eyes).The images of the upper,lower,nasal and temporal chamber angles of the patients in supine and sitting position were collected by two sonographers using water capsule ultrasound biometric microscopy.Open angle degree(AA)and angle openning distance(AOD500)of the upper,lower,nasal and temporal chamber angles of the patients in supine and sitting position were measured.The reproducibility of the measurements by two sonographers for the two groups was analyzed.Anterior chamber depth(ACD),lens thickness(LT)and axial length(AL)were measured by optical biometer IOL Master 700,and the difference of each parameter between the normal group and the shallow anterior chamber group was compared.Results Two sonographers had good reproducibility for the measurement of two groups.When the position of the two groups changed from supine to sitting position,AA and AOD500 of upper chamber angles narrowed,and AA and AOD500 of lower chamber angles widened,with statistically significant differences(all P<0.001),while no significant differences in AA and AOD500 of nasal and temporal chamber angles were observed.There were significant differences in AA of upper and lower between the normal group and shallow anterior chamber group in modified sitting position(P=0.048,0.044),and the AOD500 of upper and lower in the modified sitting position had significant differences(P=0.046,0.031),there was no significant difference in the comparison of nasal,temporal AA and AOD500 in modified sitting position.There were significant differences of ACD and LT bet
