Does aqueous secretion typically increase or decrease as we age?

As individuals age, the secretion of aqueous humor generally tends to decrease. This decline in aqueous production is associated with several physiological changes occurring in the eye and the body over time. One reason for this decrease is the reduction in the functional activity of the ciliary body, which is responsible for producing aqueous humor. Additionally, changes in the overall metabolic processes in aging may lead to a lower production rate of fluids in various tissues, including the eye.

This reduction in aqueous humor can have implications for intraocular pressure (IOP), which may also tend to decline in older adults. It is important for ocular health to monitor these changes, as they can influence the risk of conditions such as glaucoma, where adequate aqueous humor dynamics are critical for maintaining healthy IOP levels. Understanding these physiological changes can aid in formulating appropriate management strategies for aging patients.
