摘要
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２５°范围：平均光敏感度阈值分别为：干性组（３３３０±２４９），正常老年人组（３５６１±１３７），组间经ｔ检验均有高度显著性差异５°范围：干性组：（３２９５±１８２），正常老年人组（３４９３±１４６），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２５°ＤＭＭＭ总丢失量：干性组（１６０３±４４９５），面积相对数：（１３９７±１５４３）％，５°：干性组（１０６０８±１７２６８），（１２５５±１４１０）％，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。
DMMM designed by Humphrey-640 was used to examine 16 normal controls (24 eyes) and 51 AMD patients (71 eyes). Results: at 2.5 degree of macula, the mean light sensitivity (MLS) is (35.61±1.37) in the normal elderly group, but (32.95±1.82) in the dry type group, with T test between the groups being significantly high; at 5 degree of macula, the mean light sensitivity (MLS) is (32.95±1.82) in the dry type group, but (34.93±1.46) in the normal elderly group, with T test between the groups being significantly high. The results showed that DMMM experienced an early change of MLS value, that the distance among DMMM spots got small enough to combine with cumputer picture analysis, and that the sensitivity was increased when the two kinds of methods were used.
