目的:了解广西地区汉族正常人群视盘参数的正常值。方法:将3代居住广西隆林县无血缘关系的120例正常汉族成年人纳入研究。运用海德堡视网膜断层扫描仪(heidelberg retina tomograph-Ⅱ,HRT-Ⅱ)分别检测不同年龄段汉族人群视乳头地形图总体参数,视盘参数包括视盘面积(DA)、视杯面积(CA)和容积(CV)、盘沿面积(RA)和容积(RV)、视乳头轮廓线高度变化值(HVC)、视杯形态(CSM)、视杯平均深度(MCD)和最大深度(MxCD)、杯/盘面积比(C/DAR)、沿/盘面积比(R/DAR)、平均视网膜神经纤维层厚度(mRNFLT)和横截面积(RNFLA)。结果:正常汉族人视盘参数正常值:DA为2.2165±0.4266mm2,CA为0.4816±0.2979mm2,RA为1.7311±0.3217mm2,C/DAR为0.2074±0.1092,R/DAR为0.7923±0.1091,CV为0.1076mm3,RV为0.5196±0.1519mm3,MCD为0.2055±0.0798mm,MxCD为0.6039±0.1949mm,HVC为0.4513±0.1639mm,CSM为-0.2155±0.0617mm,mRNFLT为0.3059±0.0845mm,RNFLA为1.5785±0.3830mm2。按年龄分成4组,正常汉族人mRNFLT和RNFLA值与年龄均呈负相关。结论:HRT-Ⅱ可定量检测广西汉族正常人视盘参数,年龄对视乳头地形图参数有一定影响。

AIM:To study the optic disc parameters of normal people in Han nationality in Guangxi.METHODS:One hundred and twenty blood-unrelated nomoral volunteers living in Lonlin region of Guangxi were involved in the study and divided into 4 groups according to their ages.Heidelberg retina tomograph-Ⅱ(HRT-Ⅱ)was used to obtain the optic disc parameters.The parameters included optic disc area(DA),cup area(CA),cup volume(CV),rim area(RA),rim volume(RV),height variation contour(HVC),cup shape measure(CSM),mean cup depth(MCD),maximum cup depth(MxCD),cup/disc area ratio(C/DAR),rim/disc area tatio(R/DAR),mean retinal nerve fiber layer thickness(mRNFLT) and cross-section area(RNFLA).RESULTS:The parameters of optic nerve head(ONH) in normal eyes were as follows:DA(2.2165±0.4266)mm2,CA(0.4816±0.2979)mm2,RA(1.7311±0.3217)mm2,C/DAR(0.2074±0.1092),R/DAR(0.7923±0.1091),CV(0.1076)mm3,RV(0.5196±0.1519)mm3,MCD(0.2055±0.0798)mm,MxCD(0.6039±0.1949)mm,HVC(0.4513±0.1639)mm,CSM(-0.2155±0.0617)mm,mRNFLT(0.3059±0.0845)mm,RNFLA(1.5785±0.3830)mm2.The normal volunteers were divided into 4 groups according to their age and a negative correlation was found between mRNFLT,RNFLA and age.CONCLUSION:HRT-Ⅱ can be used to measure optic disc parameters of normal people in Han nationality.The age influence should be paid attention to in measuring.
