Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Laser speckle flowography (LSFG) will be used to evaluate resting retinal blood flow, retinal blood flow every 4 seconds during 1 minute of 8 Hz flicker stimulation, and retinal blood flow every 4 seconds during 1 minute after the end of flicker stimulation. Similarly, LSFG will be used to evaluate resting retinal blood flow, retinal blood flow every minute during 5 minutes of exercise with 2-3 kg dumbbells, and retinal blood flow after the end of exercise. Ocular perfusion pressure and retinal blood flow changes during each loading test from rest will be compared. | — |
