Figure 3. Temporal retinal and coronary responses to hyperoxia.
Individuals with diabetes compared to healthy controls had impaired coronary artery vasoconstrictor responses to hyperoxia throughout hyperoxia (one, three, and five minutes) (A). The percent changes in retinal arteriolar diameter responses to hyperoxia were attenuated in individuals with diabetes compared to healthy controls with significant differences observed at five minutes of hyperoxia (B). Similar responses were seen in the retinal venules (C). Type2DM =Type 2 Diabetics; * P<0.05 significant difference between individuals with diabetes compared to healthy controls.
