What is the earliest phase of retinal circulation in fluorescein angiography?
arteriovenous phase
The retinal circulation appears 1-3 seconds later (11-18 seconds after injection). The early arteriovenous phase describes the filling of the retinal arteries, arterioles and capillaries. This is followed by the late arteriovenous phase or laminar venous phase as the dye fills the veins in a laminar pattern.

It is essential to gain a greater understanding of this process in order to develop improved treatments for diabetic retinopathy.
