What is the effect of caffeine on aqueous humor production?

Caffeine has been found to have a significant impact on the production of aqueous humor by the ciliary body within the eye. Specifically, caffeine tends to inhibit the secretion of aqueous humor. This action can be attributed to caffeine's mechanisms as a central nervous system stimulant and its interactions with various adenosine receptors. By affecting adenosine receptors, caffeine can block the actions normally promoted by adenosine, leading to a reduction in the rate of aqueous humor formation.

Studies have indicated that the consumption of caffeine may lead to decreased intraocular pressure, which is often related to changes in aqueous humor dynamics. Therefore, the correct response regarding the impact of caffeine on aqueous humor production is that it decreases production. This understanding is essential for grasping the implications of dietary caffeine intake on ocular health and intraocular pressure management.
