摘　　要：目的探讨正常人的视网膜神经纤维层厚度（ｒｅｔｉｎａｌｎｅｒｖｅｆｉｂｅｒｌａｙｅｒｔｈｉｃｋｎｅｓ，ＲＮＦＬＴ）及其象限比值与年龄的关系。方法应用视神经纤维分析仪（ｎｅｒｖｅｆｉｂｅｒａｎａｌｙｓｅｒ，ＮＦＡ）检测１９８例（１９８只眼）正常志愿者，并按年龄分组进行统计分析。结果ＲＮＦＬＴ与年龄成负相关（ｒ＝－０４６，Ｐ＜００１），上、下方象限厚度较鼻、颞侧大，与年龄相关；鼻、颞侧无此特点。上、下方象限厚度比值平均为１０４１。结论ＮＦＡ是测量ＲＮＦＬＴ的可靠方法，正常人的ＲＮＦＬＴ随年龄的增长而减少。Objective To study the retinal nerve fiber layer thickness (RNFLT) of normal eye and the correlation with age. Methods RNFLT of 198 cases of normal eyes were examined by using nerve fiber analyzer (NFA). Results There were significant inverse linear correlation between the RNFLT and age (r=-046, P<001). In the analysis by the quadrant, the RNFLT was correlated with age in the superior and inferior quadrant. The mean ratio of superior and inferior quadrant thickness (S/I) was 1041. Conclusion NFA seems to be an useful tool to measure the RNFLT quantitatively. The RNFLT of normal eye is found to be decreased with age
