Exhibitionism is the act of exposing in a public or semi-public context ones intimate parts – for example, the breasts, genitals or buttocks. The practice may arise from a desire or compulsion to expose themselves in such a manner to groups of friends or acquaintances, or to strangers for their amusement or sexual satisfaction, or to shock the bystander. Exposing oneself only to an intimate partner is normally not regarded as exhibitionism. In law, the act of exhibitionism may be called indecent exposure, "exposing ones person", or other expressions. History
Public exhibitionism by women has been recorded since classical times, often in the context of women shaming groups of men into committing, or inciting them to commit, some public action. The ancient Greek historian Herodotus gives an account of exhibitionistic behaviors from the fifth century BC in The Histories. Herodotus writes that: When people travel to Bubastis for the festival, this is what they do. Every baris carrying them there overflows with people, a huge crowd of them, men and women together. Some of the women have clappers, while some of the men have pipes which they play throughout the voyage. The rest of the men and women sing and clap their hands. When in the course of their journey they reach a community — not the city of their destination, but somewhere else — they steer the bareis close to the bank.
Amaurosis fugax (Greek amaurosis meaning darkening, dark, or obscure, Latin fugax meaning fleeting) is a painless temporary loss of vision in one or both eyes. Signs and symptoms
The experience of amaurosis fugax is classically described as a temporary loss of vision in one or both eyes that appears as a "black curtain coming down vertically into the field of vision in one eye;" however, this altitudinal visual loss is relatively uncommon. In one study, only 23.8 percent of patients with transient monocular vision loss experienced the classic "curtain" or "shade" descending over their vision. Other descriptions of this experience include a monocular blindness, dimming, fogging, or blurring. Total or sectorial vision loss typically lasts only a few seconds, but may last minutes or even hours. Duration depends on the cause of the vision loss. Obscured vision due to papilledema may last only seconds, while a severely atherosclerotic carotid artery may be associated with a duration of one to ten minutes. Certainly, additional symptoms may be present with the amaurosis fugax, and those findings will depend on the cause of the transient monocular vision loss. Cause
Prior to 1990, amaurosis fugax could, "clinically, be divided into four identifiable symptom complexes, each with its underlying pathoetiology: embolic, hypoperfusion, angiospasm, and unknown". In 1990, the causes of amaurosis fugax were better refined by the Amaurosis Fugax Study Group, which has defined five distinct classes of transient monocular blindness based on their supposed cause: embolic, hemodynamic, ocular, neurologic, and idiopathic (or "no cause identified").
