Abstract： 目的探讨黄斑色素(macular pigment,MP)与黄斑区视锥细胞功能的相互关系.方法对临床确诊的16例Stargardt患者的32只眼,3例黄斑裂孔患者的3只眼用激光扫描检眼镜(scanning laser ophthlmoscope,SLO)进行黄斑区MP密度的检测.通过SLO的氩激光蓝色及红外波段进行MP的诊断与密度分级.用自编的计算机C++程序进行MP密度评估,并将MP分为完整MP、部分MP及MP缺失3级.对比分析MP分级与Snellen视力检查结果的相互关系.结果视力低于20/200的13只眼全部表现为MP缺失;视力等于或高于20/40的11只中10只眼表现为完整MP,1只眼表现为部分MP;视力介于两者之间的11只眼表现为部分MP.检测结果无病种间的差别.结论MP与患者的视力密切相关,是黄斑区视锥细胞功能完整的标志.
