摘要
采用Ｈｕｍｐｈｒｅｙ视野分析仪黄斑阈值（包括四种色光阈值）程序和ＦＭ１００—色调试验仪对５２例（６９眼）早期老年性黄斑变性（ＳＭＤ）患者进行了黄斑光敏度及色调分辨力测定。所有的病人视力或矫正视力＞１．０，眼底有玻璃疣。结果显示：早期ＳＭＤ光阈值平均ｄＢ值与色调分辨力错误记分有相关关系，其色调分辨力与红及蓝光阈值有显著相关（Ｐ＜０．０２５），与白及绿光阈值有非常相关（Ｐ＜０．００５），总错误记分增高的患者平均ｄＢ值降低明显，揭示ＳＭＤ早期颜色明度敏感性和色调分辨力两种色觉生理特性损害有平行关系。
he macular
threshold(included four color thresholds)program of Humphrey field analyzer and FM100-hue
test were used for measuring the macular light sensitivity (included fovea sensitivity )52
patients(69eyes)with early senile macular degeneration(SMD),respectively.All the patients with
drusen had best cor-rected visual acuity 1.0 or better. The results showed that there were
significant correlation between hue dis-crimination and red or blue color brightness sensitivity ,
and very significant correlation between hue discrimi-nation and white or green color brightness
sensitivity. The lose of macular light sensitivity was very marked inthe patients with higher total
error scores,The authors suggested that the impairment of the patients withearly SMD between
color brightness sensitivity and dicrimination be paralleled relation.
