Micropsia Proposal

Important Information
Micropsia is a neurological condition that affects human visual perception, causing images to become distorted so that objects are perceived to be smaller than they actually are. The condition of micropsia can have multiple causes, including head trauma, swelling of the cornea (often linked to the Epstein-Barr virus), or neurological dysfunction.
Micropsia, as well as the related condition macropsia, is one of the conditions noted in Alice in Wonderland Syndrome.
Hemimicropsia is a form of micropsia that is localized to one hemisphere of the brain. Studies of patients affected with hemimicropsia indicate that the condition is caused by brain lesions.
