Dual beam Doppler Fourier-domain Optical coherence tomography (DOCT) is a noninvasive technique to quantify total retinal blood flow.
To enable further development of this technique it is essential to assess short- and long-term reproducibility of DOCT blood flow measurements.

Dual beam Doppler Fourier-domain OCT (DOCT) Dynamic Vessel Analyzer (DVA) Optical coherence tomography (OCT)
Device: Dual beam Doppler Fourier-domain OCT (DOCT)
Retinal blood flow will be assessed using DOCT.
Device: Dynamic Vessel Analyzer (DVA)
Retinal vessel diameters and oxygen saturation will be measured with the DVA device.
Device: Optical coherence tomography (OCT)
Retinal morphology will be imaged using OCT.
- Retinal blood-flow variation over time [ Time Frame: 14 +/- 3 days ]as measured using DOCT
- Flicker induced blood flow alterations [ Time Frame: 14 +/- 3 days ]as measured using DOCT
- Flicker induced vasodilatation and hyperemia [ Time Frame: 14 +/- 3 days ]as measured using DOCT and DVA
