编辑先生，Amsler图和M图是检测视物变形的有用工具，但方法不同；Amsler图使用网格，而M图使用虚线[1，2]。以前的研究比较了这两种方法在老年性黄斑变性(AMD)[3]和黄斑水肿[4]患者中的视物变形检测率，并表明M图在检测这两种病因上的视物变性方面优于Amsler表。然而，不同的黄斑疾病之间视物变形的检测率的差异仍然不清楚。在这项研究中，我们比较了Amsler图表和M图表对不同黄斑疾病的视力变形检测的差异。这项研究是对兵库医学院2016年7月至2019年12月连续治疗的黄斑疾病患者的回顾。我们包括在同一天接受Amsler图表和M图表(稻田，东京)的患者。这项研究排除了患有黄斑疾病以外的系统性或眼部疾病的患者，这些患者对视觉功能有影响。标准Amsler图(黑色背景上的白色网格)和M图检查在30 cm的距离上进行，并由专业矫形师对眼底进行适当的近距离矫正
Dear Editor, Amsler chart and M-CHARTS are useful tools to detect metamorphopsia, but the method is different; Amsler chart uses grids, while M-CHARTS uses dotted lines [1, 2]. Previous studies compared the rate of metamorphopsia detection between these two methods in patients with age-related macular degeneration (AMD)[3] and macular edema [4] and suggested that the M-CHARTS were superior to the Amsler chart in detecting metamorphopsia in both etiologies. However, the differences in the rates of metamorphopsia detection remain unclear among various macular diseases. In this study, we compared differences in the detection of metamorphopsia between Amsler chart and M-CHARTS for various macular diseases.This study was retrospective of consecutive patients who had macular disease at Hyogo College of Medicine from July 2016 through December 2019. We included the patients who underwent Amsler chart and M-CHARTS (Inami, Tokyo) on the same day. The study excluded patients if they had systemic or ocular disease other than macular disease with an effect on visual functions. Standard Amsler chart (white grid on a black background) and M-CHARTS examinations were performed at a distance of 30 cm with appropriate near correction by professional orthoptists blinded to the fundus
