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&lt;0.001) and strongly correlated (R=0.879, p&lt;0.001). The METAVISION score was highly correlated with the stages of MTM (R=0.837, p&lt;0.001), whereas there was a moderate correlation between the M-CHARTS M-score and the stages of MTM (R=0.679, p&lt;0.001).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Quantification of metamorphopsia is important and useful for MTM management.
