单侧老年性黄斑变性对侧眼的FM100-色调分辨力的测定

FM100-Hue test measurement for color discrimination in the fellow eye of patients with age-related macular degeneration

本文采用 FM100-色调试验仪分别对单侧 AMD 对侧眼、双眼黄斑玻璃疣患者及正常对照组36例(36只眼)进行了色调分辨力检测,所有的患者视力或矫正视力≥1.0,眼底有玻璃疣。结果显示,单侧AMD 对侧眼与黄斑玻璃疣患者色调分辨力比较,红色区及全色区差异有显著性(P<0.05),蓝绿色区差异有非常显著性(P<0.003),单侧 AMD 对侧眼的色调分辨力与正常对照组比较有非常显著性差异(P<0.001),蓝绿色区分辨力与单侧 AMD 对侧眼的玻璃疣数量和融合程度有关。

Thirty-six patients with normal vision in one eye coupled with advanced age-related macular degeneration(AMD)in the fellow eye,and 36 eyes with drusen in one eye coupled with macular drusen in the fellow eye,and 36 normal subjects(36 eyes) were measured by FM100-Hue test.All the tesed eyes had corrected vision of 1.0 or better and had drusen in the fundus.The results showed that the total errors score of FM100-Hue test of patients whose fellow eye suffered from advanced AMD compared with that of the patients whose fellow eye did not suffer from advanced AMD,difference between the two groups in the red and panchromatic regions was statistically significant(P<0.05),and in the blue-green region was statistically highly significant(P<0.003).The ability of hue discri- mination of patients whose fellow eye suffered from advanced AMD was worse than that of normal subjects,difference between them being statistically highly significant(P<0.001).The color defect in blue-green region correlated with the number and confluence of drusen in patients whose fellow eye suffered from advanced AMD.
