Metamorphopsia: An Overlooked Visual Symptom

Edoardo Midena, Stela Vujosevic

Research output: Contribution to journalArticlepeer-review


Metamorphopsia is a common symptom in different macular disorders. Micropsia and macropsia are special types of metamorphopsia. Recent theories suggest that both retinal and cortical mechanisms are involved in the development and changes of metamorphopsia. Different functional tests have been proposed for the evaluation of metamorphopsia: from the Amsler grid to the hand-held mobile devices for home monitoring. This review addresses some new insights into the pathophysiology of metamorphopsia and different available tests for the evaluation of this symptom in most common macular disorders. The importance of quantification of metamorphopsia in macular diseases is confirmed by the most recent therapeutic approaches.
