应用黄斑区密集点矩阵视野（ｄｅｎｓｅｍａｔｒｉｘｍａｐｐｉｎｇｉｎｍａｃｕｌａｒ，ＤＭＭＭ）研究并结合电子计算机眼底图像分析老年黄斑变性（ａｇｅ－ｒｅｌａｔｅｄｍａｃｕｌａｒｄｅｇｅｎｅｒａｔｉｏｎ，ＡＭＤ）患者视野光敏感度（ｌｉｇｈｔｓｅｎｓｉｔｉｖｉｔｙ，ＬＳ）与眼底的改变，以找出眼底病变与ＤＭＭＭ光敏感度改变的规律及其危险因素。用Ｈｕｍｐｈｒｅｙ－６４０视野计自行设计ＤＭＭＭ检测ＡＭＤ干性组５１人７１眼，湿性组２３人２７眼。结果：干性组在随访的１８个月中有１例（１．４３％）发生湿性改变，２７眼湿性病例中５眼（１８．５２％）眼底病变转化为瘢痕，前后两次ＤＭＭＭ光敏感度对照，２例显著性检验差异有显著性，３例显著性检验差异无显著性。结论：ＤＭＭＭ降低是干性ＡＭＤ的危险因素，并有易于定量的优点，湿性ＡＭＤ眼底病变转化为瘢痕后部分病例视野光敏感度的改变与原来的比较有进步
To investigate the changes of light sensitivity (LS) and fundus fundus in patients with age-related macular degeneration (AMD) by using densematrixmappinginmacular (DMMM) and computerized fundus fundus images, The Change of DMMM Light Sensitivity and Its Risk Factors. Using Humphrey-640 visual field design DMMM detection AMD dry group 51 71 eyes, wet group 23 27 eyes. Results: In the 18-month follow-up, 1 case (1.43%) in the dry group had a wet change, and 5 eyes (18.52%) in 27 wet eyes had converted to scar, and the DMMM photosensitivity In the control group, there were significant differences between the two groups in the significance test, but there was no significant difference in the three significant tests. CONCLUSIONS: DMMM reduction is a risk factor for dry AMD and has the advantage of being easy to quantify. Changes in the photosensitivity of visual field in some cases after the conversion of wet AMD fundus to scar have been improved compared with the original
