Abstract

We developed a novel ophthalmic imaging platform that combines non-invasive measurements of retina/choroid structure and ocular blood flow based on optical coherence tomography (OCT) and wide-field semi-quantitative global flow visualization using line-scanning Doppler flowmetry (LSDF). The combination of these two imaging modalities within the same imaging platform enables comprehensive assessment of blood flow in retina and choroid and provides efficient characterization of blood flow in hemodynamic studies both in human volunteers and in small animals. The platform enables visualization of the entire posterior hemisphere vasculature, including vortex veins, using only light and without additional contrast agent in humans and rats.
