Ocular blood flow refers to the circulation of blood within the eye, supplying essential nutrients and oxygen to its various structures. This flow is crucial for maintaining the health of the retina, optic nerve, and other ocular tissues. Proper blood flow helps support visual function and overall eye health. The regulation of ocular blood flow is influenced by factors such as intraocular pressure and systemic blood pressure. Any disruption in this flow can lead to conditions like glaucoma or diabetic retinopathy, which can impair vision. Understanding ocular blood flow is vital for diagnosing and treating eye diseases.
