Interventions
DEVICE

Dynamic Vessel Analyzer (DVA)

Retinal neurovascular coupling, Retinal vessel diameters and Retinal oxygen saturation will be assessed using the DVA

DEVICE

Fourier domain optical coherence tomography (FDOCT)

Retinal blood velocities and Retinal blood flow will be assessed using the FDOCT

DEVICE

Optical coherence tomography (OCT)

Retinal nerve fiber layer thickness, Central retinal thickness and Retinal vessel density will be assessed using the OCT

DEVICE

Laser Speckle Flowgraphy (LSFG)

Normalized blur and Relative flow volume will be assessed using the LSFG

DIAGNOSTIC_TEST

Proteomics and Metabolites in Plasma, tear fluid and finger sweat

Proteomics and Metabolites in Plasma, tear fluid and finger sweat will be assessed using a Blooddraw, filter paper and Schirmer-test
