Vascular autoregulation is defined as the ability of a vascular bed to keep blood flow constant despite changes in ocular perfusion pressure. In the eye, the retinal circulation and also to a certain degree the choroidal circulation exhibit autoregulatory properties in response to changes in blood or intraocular pressure. Interestingly, it has been shown that these autoregulatory properties are compromised in ocular diseases such as glaucoma or diabetic retinopathy. New tools such as OCT angiography allow now for the investigation of vascular changes up to the microvascular level. The current talk will summaries how these new technologies can be used to get more insight in the complex regulation of blood flow in the eye.
