原发性闭角型青光眼双眼前节结构及眼轴长度的对比

目的 原发性闭角型青光眼双眼发病常有先后之别问题进行初步探讨.方法 收集2007年1月至5月治疗的原发性闭角型青光眼患者82例,其中急性闭角型青光眼58例,慢性闭角型青光眼24例.使用超生生物显微镜(UBM)和IOL-master测量原发性闭角型青光眼患者双眼前房深度及眼轴长度,A超测角膜厚度、晶体厚度,角膜地形图测量角膜曲率,比较先发病眼与对侧眼之间有无差异.结果 急性闭角型青光眼患者先发病眼UBM前房深度值为(1.78±0.25)mm,对侧眼(1.86±0.24)mm,差异有统计学意义(t=4.15,P<0.01);慢性闭角型青光眼患者先发病眼UBM值为(2.02±0.30)mm,对侧眼为(2.05±0.28)mm,差异无统计学意义(t=0.36,P>0.05).急性闭角型青光眼患者先发病眼IOL-master前房深度值为(2.36±0.19)mm,对侧眼(2.38±0.26)mm,差异无统计学意义(t=0.59,P>0.05);慢性闭角型青光眼患者先发病眼值为(2.54±0.30)mm,对侧眼为(2.57±0.24)mm,差异无统计学意义(t=0.63,P>0.05).急性闭角型青光眼患者先发病眼IOL-master测量的眼轴长度值为(22.42±0.88)mm,对侧眼(22.47±1.01)mm,差异无统计学意义(t=0.39,P>0.05);慢性闭角型青光眼患者先发病眼值为(22.62±1.07)mm,对侧眼为(22.61±1.12)mm,差异无统计学意义(t=0.113,P>0.05).急性闭角型青光眼患者先发病眼A超测得角膜厚度值为(563±41.21)mm,对侧眼(552±26.77)mm,差异无统计学意义(t=0.986,P>0.05);慢性闭角型青光眼患者先发病眼值为(558±38.25)mm,对侧眼为(555±28.21)mm,差异无统计学意义(t=0.894,P>0.05).急性闭角型青光眼患者先发病眼A超测得晶体厚度值为(4.91±0.37)mm,对侧眼(4.84±0.31)mm,差异无显著性(t=1.061,p>0.05);慢性闭角型青光眼患者先发病眼值为(4.76±0.31)mm,对侧眼为(4.77±0.30)mm,无显著差异(t=-0.113,P>0.05).急性闭角型青光眼患者先发病眼角膜地形图测得角膜曲率值为(44.92±1.21)D,对侧眼(44.76±1.05)D,差异无统计学意义(t=1.348,P>0.05);慢性闭角型青光眼患者先发病眼值为(44.79±1.26)D,对侧眼为(44.68±1.22)mm,差异无统计学意义(t=1.194,P>0.05).结论 原发性急性闭角型青光眼患者双眼发病先后之别与双眼前房深度的差异有一定关系.

The compare of anterior chamber structure and axial length between two eyes of primary angle close glaucoma

Objective The onset of two eyes of primary angle-closure glaucoma often is not at the same time.Whether this difference is related with anterior chamber structure and axial length? The question had been discussed in this paper.Methods The anterior chamber depth,axial length,corneal thickness,corneal curvature of 82 patients with primary angle-closure glaucoma were observed with ultrasound biomicroscopy, I-OL-master,A-ultrasound and corneal topography.The result were compared between two eyes.Results The anterior chamber depth with UBM of primary acute angle-closure glaucoma had significant deviation between two eyes.The axial length,corneal thickness,corneal curvature had no deviation in APACG.The anterior cham-ber depth, axial length, corneal thickness, corneal curvature all had no deviation in chronic PACG.Conelusion The difference onset time of two eyes of primary acute angle-closure glaucoma is related to the deviation of an-terior chamber depth.
