Harris et al. [2] also provided evidence
of the presence
of retinal hypoxia
in the early stages
of diabetes by showing that contrast sensitivity was improved when patients with early
diabetic retinopathy were made hyperoxic.
In most cases, hypoxia is caused by either a dysfunction of the retinal vasculature, as in diabetic retinopathy and retinal artery and vein occlusions, or it is due to a mismatch between nutrient supply and demand, as in the case of a retinal detachment, where the retina is separated too far from the choroid to receive sufficient oxyge
