Myopic patients having decreased ocular rigidity
transmits greater force of contraction of ciliary muscles to the choroid and sclera.
Ocular rigidity is a macroscopic parameter characterizing the relationship between pressure and volume changes in the human eye.
Although it is well known that diabetes mellitus interferes with the vascular integrity of the ocular tissues , the relationship between diabetes and ocular rigidity has received little attention.
The relationship between IOP increase and infused volume was used to calculate the ocular rigidity coefficient  while the IOP decay during outflow was used to calculate the outflow facility coefficient .
(8) The increase of IOP with age may be caused by age-dependent changes of ocular rigidity
. In humans, an increase of ocular rigidity
was observed with increasing age and was positively correlated to IOP.
(16,17) As none of the tonometers used in the present study allowed the evaluation of CCT or other parameters which may affect IOP measurement such as ocular rigidity
or hysteresis, we used IOP values adjusted for CCT in our analysis.

Moreover, myopic eyes have a lower ocular rigidity than emmetropic and hyperopic eyes [27, 28].
