Current Concepts in Retinal Vascular Imaging

The human circulation is difficult to visualize directly in vivo. The retinal circulation, on the other hand, can be imaged non-invasively with a fundus camera, and the retinal vessels share similar embryological origin, anatomical features and physiological properties with the cerebral circulation. Thus, studying the health of the retinal vessels offers a unique and easily accessible "window" to study early pathways and consequences of major vascular diseases such as stroke and heart disease
