| 目的 用HRT-Ⅱ测量我国正常成人视盘结构参数并探讨性别、眼别、年龄及视盘面积大小对视盘结构的影响。方法 对2004—2007年在中山眼科中心就诊的正常人156例进行HRT-Ⅱ检查,随机选择1眼进行视盘地形图总体参数分析,用Pearson相关分析分析年龄、视盘面积大小对视盘结构的影响和视盘各参数间的相关关系。结果 我国正常人156例156只眼视盘地形图正常平均值:视盘面积(DA)为(2.00±0.38)mm2、视杯面积(CA)为(0.45±0 |

| Objective To study the optic nerve head (ONH) parameters and topograph features of normal subjects, and analyze the effect of gender, laterality, age and disc size on the topograph of ONH. Methods Heidelberg Retina Tomograph (HRT-Ⅱ) was used to obtain the optic nerve head parameters and topograph images in 156 eyes of 156 normal volunteers aged 20－80 years old.Results The parameters of ONH in normal eyes were as following: disc area (DA) (2.00±0.38)mm2, cup area (CA) (0.45±0.25) mm2, rim area (RA) (1.54±0.31)mm2, cup/disk area ratio (C/DAR) (0.22±0.10), rim/disk area ratio (R/DAR) (0.78±0.10), cup volume (CV) (0.09±0.07)mm3, rim volume (RV) (0.47±0.14)mm3, mean cup depth (MCD) (0.22±0.07)mm, maximum cup depth (MxCD) (0.62±0.17)mm, height variation contour (HVC) (0.45±0.10), cup shape measure (CSM) (－0.19±0.06), mean retinal nerve fiber layer thickness (mRNFLT) (0.30±0.08)mm, retinal nerve fiber layer cross section area (RNFLA) (1.50±0.37)mm2, horizontal cup/disk ratio (H C/DR) (0.45±0.17), and vertical cup/disk ratio (V C/DR) (0.35±0.79). There was no difference between different genders and different eyes in all parameters. A negative correlation was found between mRNFLT, RNFLA, HVC,RV, MxCD and age. Only CSM had a positive correlation with age. Disc area significantly influenced most of the parameters, except MxCD and HVC. Conclusion HRT-Ⅱcan obtain optic nerve head parameters and topograph images quickly and accurately. Age and disc area influence some topographic parameters of the optic nerve head in the Heidelberg Retina Tomograph ONH analysis. It needs to take account of these factors when analyzing ONH by HRT-Ⅱ. |
