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变患者变幻觉的新型系统


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，并探索 MTM 的模式。设计 观察性、横断面研究。方法 我们设计了一个新的系统。结果 在测试的 445 只眼睛中，188 只 （42.25%） 被患者认为有影响日常生活的变形，而 257 只 （57.75%） 被认为没有变形症状。Amsler 网格、 M-CHARTS 和 METAVISION 测试显示对视物的敏感性分别为 95.74% 、 89.89% 和 100%。Amsler 网格、M-CHARTS 和 METAVISION 测试的特异性为 100%。变形视问卷和 METAVISION 评分高度一致 （平均组内相关系数 = 0.951，p<0.001） 和强相关 （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）。结论的定量对 MTM 管理很重要和有用。METAVISION 是一种临床适用的综合方法，用于量化视物，可用于临床环境。数据可应合理要求提供。没有可用的数据。不適用。
