Comparison to Fluorescein Angiography


3


ADVANTAGES OF OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY


¤      Noninvasive


¤      Higher resolution


¤      Rapid acquisition time


¤      No intravenous injection; avoids dye-related side effects


¤      Simultaneous viewing of structure and vascular information


¤      Volumetric data with segmentation allows for precise identification of lesion


¤      No dye leakage, thus boundaries of capillary dropout and neovascularization can be more precisely measured


¤      Imaging of retinal and choroidal vasculature


DISADVANTAGES OF OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY


¤      Limited field of view


¤      Artifacts may lead to false negatives and false positives


¤      No dye leakage results in limited information that is time dependent


¤      Slow moving blood may result in poor detection of pathology
