A team of scientists led by Dorota Skowronska-Krawczyk of the University of California, Irvine has found how stress affects the retina. It turns out that due to the increase in intraocular pressure in the retinal tissues, changes occur similar to those that occur during natural aging. Repetitive stress accelerates the aging process even more.
With aging, all cells of the body are affected. As for the eyes, a person may develop glaucoma due to aging.
In humans, intraocular pressure has a circadian rhythm. In healthy people, this pressure is usually in the range of 12 to 21 mm Hg. Art. Intraocular pressure is highest at night in 2/3 of people.
According to animal studies, even a moderate increase in intraocular pressure contributes to the loss of retinal ganglion cells and the associated visual defects.
