Table 2.
Oxygen saturation and peripapillary oxygen exposure values in glaucoma patients in groups. Based on the median VFR glaucoma subjects were divided in two groups: VFR group with ≤2.9% VFR dilatation from the baseline diameter and the VFR group with >2.9% VFR dilatation from the baseline diameter. The respective oxygen saturation and peripapillary oxygen exposure values of controls are given for comparison. Statistically significant values (p < 0.05) are given in bold.
