- macroptic hallucination
- The term macroptic hallucination is indebted to the Greek words makros (large) and opsis (seeing). It refers to a " visual hallucination in which the object or scene in question is perceived as disproportionally large in comparison with the objects seen in regular sense perception. A variant of the macroptic hallucination depicting dis-proportionally large human figures is known as a " gulliverian hallucination. Macroptic hallucinations may present as an isolated symptom, as part of an " aura or as part of a cluster of symptoms called the " Alice in Wonderland syndrome. Eti-ologically, they are associated with such varied conditions as "delirium, "delirium tremens, alcohol withdrawal, toxoplasmosis and typhoid infections, basilar migraine, mesencephalic lesions, " Charles Bonnet syndrome, and intoxication with " hallucinogens such as LSD and mescaline. The term macroptic hallucination is used in opposition to "microptic hallucination. It should not be confused with "macropsia.ReferencesEy, H. (2004). Traité des hallucinations. Tome 1.
