Which vascular pattern indicates that the entire neurosensory retina receives a direct blood supply?

The holangiotic vascular pattern is characterized by a comprehensive and direct supply of blood to the entire neurosensory retina. This pattern features blood vessels that are distributed throughout the retina, allowing each region of the retina to receive adequate oxygen and nutrients directly from the retinal vasculature. The presence of numerous, branching retinal blood vessels ensures that even the most peripheral areas of the retina are well perfused.

In contrast, a merangiotic vascular pattern is associated with a limited vascular supply concentrated mainly at specific areas of the retina, typically sparing significant portions. This means that not all regions receive direct blood supply, potentially leading to areas at risk of ischemia.

Retinal ischemia refers to a deficiency in blood supply to the retina, which can lead to damage and a variety of retinal diseases. This condition is often a consequence of inadequate perfusion but does not directly indicate a vascular pattern.

The chorioretinal pattern involves the choroidal vessels supplying blood primarily to the outer layers of the retina, while the inner layers may have limited or no direct blood supply from the retinal vessels. This means that some sections of the retina may not receive adequate nourishment.

Given this context, the holangiotic vascular pattern stands out as it guarantees that the
