Brief Title | Multimodal Imaging of Retinal Vessels | ||
Official Title | Retinal Vessel Morphology in Multimodal Imaging | ||
Brief Summary | Retinal blood flow measurement is of scientific and clinical value. For this purpose retinal vessel morphology (such as diameter, vessel wall thickness, etc) determination is crucial. Different imaging modalities might provide divergent results. Thus, quantification of such differences is valuable. The present study aims to reveal and quantify differences in vessel morphology between fundus photography, fundus angiography, and optical coherence tomography in health and disease. |
