摘　　要：目的进一步了解年龄、性别、眼别对多焦视网膜电图（ｍＥＲＧ）测定的影响。方法４６人６０只正常眼，用Ｒｏｄｅｎｓｔｏｃｋ的 ＲＥＴＩｓｃａｎ ３． １２系统进行测定。结果 ｍＥＲＧ的各项参数变异很大，基本排除了年龄、性别（除男性全视野Ａ波潜伏期较女性长以外）、眼别的影响，但受试者瞳孔的大小、固视的好坏可直接影响测定结果。结论ｍＥＲＧ各项参数正常值范围宽，应结合病史及眼部的其他检查，不仅须注意Ａ，Ｂ波的振幅和潜伏期，还应观察波形改变和视觉山形状。Objective To study the correlations among age, sex, eye and mERG results. Methods 60 normal eyes of 46 volunteers were divided into 6 groups at different ages. RETIscan 3. 12 system of Rodenstock was used to carry out mERG examination. Results Variation of mERG parameters among normal eyes was significant. Age, sex and eyes have little influence on mERG results, except latency A was longer in male than in female. The size of pupil and fixation were found to influence the results directly. conclusions care should be exercised in explaining the results. Disease history and other examinations shoud be taken into consideration. Attention should be given to the changes in wave-form and vision mountain in addition to amplitudes and latencies.
