[目的]观察早期老年性黄斑变性(AMD)患眼黄斑色素密度(MPOD)变化以及补充叶黄素对MPOD变化的影响.[方法]通过矫正视力、眼底照相、间接检眼镜、光相干断层扫描检查确诊并排除其他眼病的42例早期AMD患者42只患眼和42只正常对侧眼纳入研究.所有患者予以每日口服叶黄素15.1 mg,持续1个月.干预前后采用异色闪烁光度测量法检测其双眼的MPOD值,对比分析补充叶黄素前后MPOD变化值与补充叶黄素前MPOD值的关系.[结果]补充叶黄素前AMD眼和正常对侧眼的MPOD平均值分别为0.347±0.182和0.426±0.173,二者比较,差异有统计学意义(t=-2.042,P=0.044).补充叶黄素后AMD眼和正常对侧眼的MPOD平均值分别为0.406±0.155、0.446±0.128,二者比较,差异无统计学意义(t=-1.283,P=0.203).与补充叶黄素前比较,补充叶黄素后AMD眼的MPOD有增高趋势,但其差异无统计学意义(t=-1.594,P=0.115).AMD眼(r=-0.552,P=0.000)和正常对侧眼(r=-0.731,P=0.000)补充叶黄素前后MPOD变化值与补充叶黄素前MPOD值均有显著的负相关性.[结论]早期AMD患眼MPOD较正常对侧眼降低；补充叶黄素对于提高早期AMD患眼MPOD有一定作用,其作用强度与治疗前MPOD值呈负相关.
