Web27 May 2024 · All these alterations in total contribute in the changes of ocular rigidity that have been described in the literature. Changes in ocular rigidity have been considered as part of the normal aging process. Scleral and corneal stiffness is known to increase with age and also choroidal compressibility is altered [ 4, 5, 6 ]. Weblar rigidity and ocular volume may sug-gest an alteration in the compliance of the sclera in myopic eyes. Abnormalities in the scleral distensibility and thickness [45–48], and choroidal thickness and blood flow [46,47,49–51] are involved in myopia patho-genesis, with stretching and thinning of the choroid and sclera as observed with netplay sweater https://colonialfunding.net
