视觉眼电图诊断指标研究

Studies on Parameters of Electro-oculogram

检测和分析了100只正常眼的多项EOG诊断指标,其中电位值参数四项,时间参数两项,比值参数四项。分析表明:电位值参数个体差异大,各作者报告正常范围相差较大,不易比较;时间参数以分为单位,精度太低,严重影响诊断价值;比值参数中,单项应用存在较大局限性,正常眼Q值和G值频数分布均较集中,其正常范围内分别为95%和97%,建议联合应用Q值和G值进行分析指导诊断。

We analysed sever al parameters of EOG on 100 eyes, involved four electrical values, two time parameters and four ratio value. The results indicate that the electrical values is obviously different among the individuls and the time parameters is lower precise and each ratio value is limited, We suggest that the application combining the Q value and G value of EOG is favourable in diagnosis.
