目的:了解壮族正常人群视盘参数的正常值并建立壮族数据库。方法:3代居住广西隆林县无血缘关系的正常壮族成年人120例。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视乳头地形图总体参数。结果:壮族人视盘正常值:DA为2.26±0.47mm2,CA为0.51±0.35mm2,RA为1.75±0.34mm2,C/DAR为0.21±0.12,R/DAR为0.80±0.12,CV为0.12mm3,RV为0.53±0.14mm3,MCD为0.21±0.10mm,MxCD为0.60±0.22mm,HVC为0.45±0.10mm,CSM为-0.20±0.07mm,mRNFLT为0.30±0.07mm,RNFLA为1.57±0.43mm2。各象限mRNFLT,RNFLA与年龄呈负相关关系。性别间和眼别间差异无统计学意义。壮族C/DAR比值双眼差值范围为0.00~0.16。结论:HRT-II可定量检测壮族正常人视盘参数,年龄对视盘参数有一定影响。

AIM: To study the optic nerve head parameters and topograph features of normal subjects in Zhuang nationality in Guangxi for establishing database. METHODS: One hundred and twenty blood-unrelated nomoral volunteers living in Longlin county of Guangxi were involved in the study.Heidelberg retina tomograph-Ⅱ(HRT-Ⅱ)was used to obtain the optic nerve head parameters. RESULTS:The parameters included optic disc area 2.26±0.47mm2,cup area 0.51±0.35mm2, CUP/disk area ratio 0.21±0.12, rim/disk area ratio 0.80±0.12, cup volume 0.12mm3,rim area 1.75±0.34mm2,rim volume 0.53±0.14mm3, height variation contour 0.45±0.10mm, cup shape measure - 0.20±0.07mm, mean cup depth 0.21±0.10mm,maximum cup depth 0.60±0.22mm,mean retinal nerve fiber layer thickness 0.30±0.07mm and cross-section area 1.57±0.43mm2. A negative correlation was found between mRNFLT,RNFLA and age. There was no significant difference between right and left eyes and between different genders in all parameters. The binocular difference value of C/DAR was 0.00- 0.16 in Zhuang nationality. CONCLUSION: HRT-Ⅱ can be used to measure optic disc parameters of normal person in Zhuang nationality.There were differences in age.
