This video discusses the utility of dynamic (video) angiography, specifically fundus fluorescein angiography (FFA) and indocyanine green angiography (ICG), in the diagnosis of retinal vascular diseases such as polypoidal choroidal vasculopathy (PCV). Still images and dynamic FFA and ICG angiography were obtained from patients seen for various retinal conditions such diabetic retinopathy, PCV, and choroidal neovascularization. Characteristic features of each condition were noted and assessed on still and dynamic angiography. Dynamic FFA features of proliferative diabetic retinopathy were shown, and the characteristic features of leakage and capillary fallout were demonstrated. Dynamic ICG angiography was also used to show the filling of the branching vascular network and pulsation of polyps. These features are not well appreciated on a still image. Dynamic angiography gives the clinician a sequential view of the circulatory phase of the retinal vasculature and is therefore useful in the diagnosis of retinal vascular diseases by enhancing the diagnostic capabilities.
