Effect of ciliary body shape and position on spatial structure in anterior segment of normal eyes

摘要:

目的:探讨正常人眼睫状体形态和位置对眼前段空间结构的影响。方法:应用超声生物显微镜(UBM)、A超、Pentacam三维眼前段图像分析仪测量186例186眼正常人睫状体厚度(CBT)、睫状突长度(CPL)、巩膜睫状突夹角(θ)、前房体积(ACV)、前房深度(ACD)、晶状体厚度(LT)、相对晶状体位置(RLP)、房角开放距离(AOD500)。采用直线相关与回归分析方法分析CBT,CPL,θ与ACV,ACD,LT,RLP,AOD500的相关关系。结果:正常人CBT,CPL,θ与ACV,ACD,LT,RLP,AOD500分别为0.740±0.099mm,1.228±0.166mm,45.81°±5.11°,171.15±44.23mm3,2.822±0.314mm,4.29±0.48mm,0.231±0.013,0.373±0.069mm。CBT与ACV,ACD,RLP正相关,与LT负相关,与AOD500无相关性;CPL与ACV,ACD,RLP,AOD500负相关,与LT正相关。θ与ACV,ACD,RLP,AOD500正相关、与LT无相关性。结论:睫状体形态与位置是眼前段空间结构差异的影响因素。

Abstract:

AIM:To evaluate effect of ciliary body shape and position on spatial structure in anterior segment of normal eyes. METHODS:Totally 186 eyes of 186 normal subjects were examined by ultrasound biomicroscopy(UBM), A scan and Pentacam scheimpflug system, including ciliary body thickness(CBT), ciliary process length(CPL) , scleral ciliary process angle(θ) ,anterior chamber volume(ACV), anterior chamber depth(ACD), lens thickness(LT) and relative lens position(RLP), angle opening distance 500μm from the scleral spur(AOD500). The correlations of CBT, CPL, θ and ACV, ACD, LT, RLP, AOD500 were analysed using linear correlation and regression analysis. RESULTS:Normal CBT, CPL, θ and ACV, ACD, LT, RLP, AOD500 were 0.740±0.099mm, 1.228±0.166mm, 45.81°± 5.11°, 171.15±44.23mm3, 2.822±0.314mm, 4.29±0.48mm, 0.231 ± 0.013,0.373±0.069mm, respectively.CBT was positive correlation with ACV, ACD and RLP, negative correlation with LT and no correlation with AOD500. CPL was negative correlation with ACV, ACD, RLP and AOD500, positive correlation with LT. θ was positive correlation with ACV, ACD,RLP and AOD500 and no correlation with LT. CONCLUSION:Ciliary body shape and position are influence factors of differences in spatial structure of ocular anterior segment.
