Ocular perfusion

ocular perfusion

Ocular perfusion refers to the blood flow that delivers oxygen and nutrients to the eye’s tissues, including the retina and optic nerve. These tissues rely on a steady supply of oxygen and glucose to function and to clear away metabolic waste, so proper perfusion is essential for clear vision and healthy eye cells. Blood flow to the eye depends on overall blood pressure, the health and caliber of the eye’s vessels, and the pressure inside the eye; changes in any of these can alter perfusion. When perfusion is reduced, the delicate nerve cells of the eye can become starved of oxygen, which increases the risk of damage and permanent vision loss. Understanding ocular perfusion matters because impaired circulation can worsen many eye conditions and influence treatment choices. Clinicians consider perfusion when evaluating eye health and may recommend interventions to improve blood flow or to manage factors that threaten it, such as high eye pressure or systemic cardiovascular problems. Lifestyle measures and medical treatments that support healthy circulation and vascular health can help protect vision. Ongoing research into monitoring and maintaining ocular perfusion aims to improve strategies for preventing vision loss as people age or face vascular disease.
