Dysmorphopsia

Dysmorphopsia, in a broad sense, is a condition which causes the person affected to be unable to correctly perceive objects. It is a visual distortion, used to denote a variant of metamorphopsia in which lines appear wavy.^[1] These illusions may be restricted to certain visuals areas, or may affect the entire visual field.^[2]

It has been associated with meningioma tumors^[3] and bilateral lateral occipital corital damage, e.g. after carbon monoxide poisoning or drug abuse.^[4]

Etymology

The term dysmorphopsia comes from the Greek words dus (bad), morphè (form), and opsis (seeing).^[5]
