This image illustrates the small blood vessels in the retina, the part of the eye responsible for detecting light. This intricate network of vessels delivers essential oxygen and nutrients to maintain healthy vision. Endothelial cells (shown in red) form capillaries and regulate the exchange of substances between the bloodstream and surrounding tissues. Smooth muscle cells (shown in green) encase the endothelial cells of retinal arteries, controlling their diameter and directing blood flow to specific areas of the eye. Damage to these vessels from aging, diabetes, or strokes can disrupt blood flow, leading to blurred vision, altered color perception, and, in severe cases, blindness. This research aims to improve blood vessel structure and function to preserve vision.
