Micropsia is a condition in which objects appear smaller than they actually are. It can be caused by various factors including migraines, brain injuries, and certain medications. There are several synonyms for micropsia, including megalopsia, which is the opposite of micropsia and causes objects to appear larger than they are. Other synonyms include anisometropia, which refers to unequal visual acuity in the two eyes, and dysmetropsia, which is a distortion of perceived distance. Another term used to describe micropsia is telegnosis, which refers to the perception of objects as being far away. These synonyms can be important in understanding and discussing visual disturbances and neurological conditions.
