Retinal Scans to Visualize the Loss of Capillary Density in the Central Nervous System

The angiogenesis hypothesis of aging suggests that loss of capillaries throughout the body is an important driver of age-related decline. This loss must be a downstream consequence of other forms of damage and dysfunction, issues that lead to a disruption of the balance of signals and cell capabilities needed to maintain the network of capillary blood vessels. Hundred of capillaries pass through every square millimeter of tissue, allowing the bloodstream to nourish the resident cells. If the density of that network declines, then ever lesser amounts of oxygen and nutrients are delivered to the cells that need them. This is particularly important in tissues requiring a great deal of energy, such as muscles and the brain. As for all aspects of aging, of course, there is
