摘要 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.
