Purpose To develop a novel system for quantifying metamorphopsia in patients with myopic traction maculopathy (MTM) and to explore the metamorphopsia pattern of MTM. Design Observational, cross-sectional study. Methods We designed a new system. Results Of the 445 eyes tested, 188 (42.25%) were deemed by patients to have metamorphopsia impacting their daily lives while 257 (57.75%) were considered to have no metamorphopsia symptoms. The Amsler grid, M-CHARTS and METAVISION tests displayed sensitivities for metamorphopsia of 95.74%, 89.89% and 100%, respectively. The specificities of the Amsler grid, M-CHARTS and METAVISION tests are 100%. The metamorphopsia questionnaire and METAVISION scores were highly consistent (average intraclass correlation coefficient=0.951, p<0.001) and strongly correlated (R=0.879, p<0.001). The METAVISION score was highly correlated with the stages of MTM (R=0.837, p<0.001), whereas there was a moderate correlation between the M-CHARTS M-score and the stages of MTM (R=0.679, p<0.001). Conclusions Quantification of metamorphopsia is important and useful for MTM management. The METAVISION is a clinically applicable and comprehensive approach for quantifying metamorphopsia, which can be used in clinical settings. Data are available on reasonable request. No data are available. Not applicable.

METAVISION：一种量化近视牵引性黄斑病患者视物变形的新型系统


目的 开发一种新的系统来量化近视牵引性黄斑病变（MTM）患者的视物变形，并探讨 MTM 的视物变形模式。设计观察性横断面研究。方法我们设计了一个新系统。结果 445只眼中，188只（42.25%）被患者认为有影响日常生活的视物变形症状，257只（57.75%）被认为没有视物变形症状。 Amsler 网格、M-CHARTS 和 METAVISION 测试显示视物变形的敏感性分别为 95.74%、89.89% 和 100%。阿姆斯勒网格、M-CHARTS 和 METAVISION 测试的特异性为 100%。视物变形问卷和 METAVISION 评分高度一致（平均组内相关系数=0.951，p<0.001）并且强相关（R=0.879，p<0.001）。 METAVISION 评分与 MTM 分期高度相关（R=0.837，p<0.001），而 M-CHARTS M 评分与 MTM 分期之间存在中等相关性（R=0.679，p<0.001）。结论 视物变形的量化对于 MTM 管理非常重要且有用。 METAVISION 是一种临床适用的综合性视物变形量化方法，可用于临床环境。可根据合理要求提供数据。无可用数据。不适用。
