Which vascular layer of the choroid has the largest blood vessels?

Explanation:
The largest blood vessels in the choroid are in Haller's layer. The choroid has three vascular layers, listed from inner to outer: the choriocapillaris (a dense network of capillaries under the RPE), Sattler's layer (medium-sized vessels), and Haller's layer (the largest-caliber arteries and veins). The suprachoroidal lamina is outside the choroid and not where the biggest vessels reside. So, the layer with the largest vessels is Haller's layer.
