What does mydriasis refer to in patients experiencing cocaine-induced psychosis?

Mydriasis refers to the dilation of the pupils, which can be a significant physiological response associated with certain drug use, including cocaine. Cocaine acts as a powerful stimulant that affects the sympathetic nervous system, leading to various effects on the body. When a person experiences mydriasis, the pupils become larger, allowing more light to enter the eye, which can also contribute to heightened visual sensations or even discomfort in bright settings.

In the context of cocaine-induced psychosis, mydriasis is often present alongside other sympathetic symptoms such as increased heart rate, elevated blood pressure, and heightened alertness. This combination of effects can create a distinct clinical picture indicative of cocaine use. Consequently, recognizing mydriasis not only aids in understanding the acute effects of cocaine but also serves as an important clinical sign that contributes to the diagnosis of substance-related disorders.
