The main function of ocular blood flow is to supply sufficient oxygen and
nutrients to the eye. Local blood vessels resistance regulates overall blood
distribution to the eye and can vary rapidly over time depending on ocular need.
Under normal conditions, the relation between blood flow and perfusion pressure
in the eye is autoregulated. Basically, autoregulation is a capacity to maintain
a relatively constant level of blood flow in the presence of changes in ocular
perfusion pressure and varied metabolic demand. In addition, ocular blood flow
dysregulation has been demonstrated as an independent risk factor to many ocular
diseases. For instance, ocular perfusion pressure plays key role in the
progression of retinopathy such as glaucoma and diabetic retinopathy. In this
review, different direct and indirect techniques to measure ocular blood flow and
the effect of myogenic and neurogenic mechanisms on ocular blood flow are
discussed. Moreover, ocular blood flow regulation in ocular disease will be
described.
