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
