In the context of adrenergic agents, it's essential to understand their typical effects on the body. Adrenergic agents, also known as sympathomimetics, generally stimulate the sympathetic nervous system and can lead to a range of physiological changes.

Pupil dilation is a well-known effect, as adrenergic agents often cause mydriasis through the activation of alpha-adrenergic receptors in the iris. This leads to the relaxation of the iris sphincter muscle.

The relaxation of the ciliary muscle is another consequence of adrenergic activity. This muscle plays a vital role in regulating the shape of the lens for focusing. When adrenergic agents are active, they typically promote relaxation, which can affect near vision.

The increased outflow of aqueous humor can also occur due to adrenergic stimulation, as this can lead to changes in the anterior chamber dynamics and further enhance fluid drainage.

In contrast, increased aqueous humor formation is not a common side effect of adrenergic agents. Generally, adrenergic agents do not promote the production of aqueous humor; in fact, they might have the opposite effect by decreasing the formation of fluid in the eye, leading to a net reduction in intraocular pressure. Therefore, increased aqueous humor formation
