    Ageing effects on ocular blood flow, oxygen tension and function during IOP elevation
    Lim, Jeremiah Kah Heng ( 2012)
    This is the first study to simultaneously measure electroretinography, ocular blood flow, and oxygen tension during intraocular pressure elevation. By doing so it shows that changes in oxygen tension are more closely related to function than blood flow. Moreover, by comparing these parameters in young and older eyes this study shows that older eyes have less oxygen availability with higher intraocular pressure despite having similar function. This argues that older eyes use more oxygen to sustain normal function.
