Arteriovenous passage times (AVP) and corresponding arterial and venous vessel diameters of the affected and less affected vessel formations (altitudinal visual field loss) (mean (SD))
| n=18 | AVP (seconds) | Arterial diameter (μm) | Venous diameter (μm) |
| Affected branch | 3.1 (1.67) | 99 (19) | 135 (28) |
| Less affected branch | 2.61 (1.44) | 101 (23) | 140 (30) |
| Significance | p=0.04 | p=0.89 | p=0.87 |
