用Ｈｕｍｐｈｒｅｙ－６４０视野计自行设计的ＤＭＭＭ检测正常对照组１６人２４眼，ＡＭＤ干性组５１人７１眼结果：黄斑区２５°范围：平均光敏感度阈值分别为：干性组（３３３０±２４９），正常老年人组（３５６１±１３７），组间经ｔ检验均有高度显著性差异５°范围：干性组：（３２９５±１８２），正常老年人组（３４９３±１４６），组间经ｔ检验均有高度显著性差异干性组眼底病灶面积与视野光敏度黄斑区２５°ＤＭＭＭ总丢失量：干性组（１６０３±４４９５），面积相对数：（１３９７±１５４３）％，５°：干性组（１０６０８±１７２６８），（１２５５±１４１０）％，显著性检验均有高度显著差异结果表明：干性组早期就有ＤＭＭＭ的平均光敏感度阈值的改变，ＤＭＭＭ点间距离变得更小与计算机图像分析的结合应用，对于眼底细微病变引起的视功能的改变检测的敏感性得到了提高 DMMM was designed by Humphrey-640 to measure 16 eyes in 24 eyes of normal control group and 51 eyes of AMD dry group in 71 eyes. Results: Macular area 2  5 ° range: average light sensitivity threshold were: dry group 30 ± 2.49), normal elderly group (3561 ± 137), there was a highly significant difference between the groups by t test  5 ° range: dry group: (3295 ± 182 ), Normal elderly group (3493 ± 146), there was a highly significant difference between the groups by t test  dry eye area and visual field sensitivity macular area 2  5 ° DMMM total loss: dry (1397 ± 1543)%, 5 °: dry group (10608 ± 17268), (1255 ± 14) 10)%, the significant test were highly significant differences  The results showed that: early dry DMMM average light sensitivity threshold changes, DMM The distance between dots becomes smaller and computer image analysis of the binding applications, the sensitivity for detecting change fundus lesions caused by subtle visual function is improved
