Arteriole phase (fluorescein angiography)

A bolus of fluorescein dye is injected into a vein in the arm. It begins to appear in the eye 10 to 20 seconds later if the injection is not prolonged and the patient’s circulation is normal. The dye, which is made to fluoresce, is first seen in the choroidal circulation followed by the retinal arteriole. This figure represents an early arteriole phase.
