Lerner and Lev-Ran described in a case report a 26-year-old patient who during an LSD intoxication presented with episodes of visual illusions in the form of macropsia, micropsia, pelopsia, and teleopsia.
These symptoms were also associated with either visual illusions, including dysmetropsia, namely, macropsia and micropsia (objects or other people appearing bigger or smaller) and telopsia and pelopsia (objects or other people appearing respectively further or nearer), or disorders of consciousness, as feelings of derealization, depersonalization, somatopsychic duality (i.e., the idea to be split in two, more often vertically in the middle), and alteration in judgment of time.

Zolpidem-induced macropsia has been reported in women with anorexia.7 The protein-binding capacity of zolpidem is approximately 92%, mainly to albumin (66%) and al-acid glycoprotein (56.6%).4 In malnourished patients with anorexia nervosa, hypoalbuminemia is common and, therefore, unbound drug concentration is higher.
In ERM, this process is usually limited to the formation of membranes above the macula that can contract and wrinkle the retina causing patients to complain of visual impairment such as metamorphopsia, micro- or macropsia, blurred vision, and occasionally monocular diplopia [7-9].
