Which adverse effect is associated with mydriatic agents?

Mydriatic agents are medications that cause dilation of the pupils, which can lead to increased sensitivity to light, commonly referred to as photophobia. When the pupils are dilated, the amount of light entering the eye increases, making bright light uncomfortable or painful for some individuals. This effect is particularly noticeable after the administration of mydriatic agents, as the normal constriction response of the pupils to bright light is inhibited.

In contrast, pupil constriction, decreased blood pressure, and appetite stimulation are not effects associated with mydriatic agents. Pupil constriction is typically the result of agents known as miotics, while mydriatics are specifically designed to facilitate pupil dilation. Decreased blood pressure and appetite stimulation are not physiological responses related to the action of mydriatic agents, and they pertain to different classes of medications and effects on the body. Understanding these specific effects helps in both theoretical knowledge and practical application in clinical settings.
