Does intraocular pressure (IOP) typically increase or decrease with age?

Intraocular pressure (IOP) typically increases with age due to various physiological changes that occur in the eye. As individuals grow older, there is a natural decrease in the outflow facility of aqueous humor through the trabecular meshwork, which can lead to a gradually higher IOP. Additionally, the changes in the sclera and overall structure of the eye contribute to this increase, as the eye may become less efficient in draining the aqueous humor.

Furthermore, age-related conditions, such as the development of cataracts and changes in the lens, can also impact IOP. Elevated IOP is a significant risk factor for glaucoma, a condition that can lead to vision loss if left untreated. Thus, recognizing the tendency for IOP to rise with age is essential for monitoring and maintaining ocular health in older adults.
