Purpose of the Study:
- To introduce and detail a novel technique: retinal rheometry.
- To evaluate the suitability of various imaging technologies for retinal rheometry.
- To present preliminary data on retinal rheometry in healthy individuals.
Main Methods:
- Development of the retinal rheometry technique.
- Comparison of imaging devices, including cameras and laser scanning ophthalmoscopes.
- Description of the data reduction pipeline.
- Pilot study in a cohort of healthy volunteers.
Main Results:
- Retinal rheometry is a feasible technique for quantifying retinal microcirculation.
- Different technological equipment show varying applicability.
- Initial data from healthy volunteers provide a baseline for the technique.
Conclusions:
- Retinal rheometry offers a promising new approach to assess retinal blood flow.
- Further validation and larger studies are warranted.
