The article discusses some important issues to consider with regards to optical coherence tomography angiography (OCTA) and what the images show in order to capture better images. Topics include the confusion over the scan terminology of OCT, the reason why OCTA should be considered an adjunct for dye angiography and not a replacement, and the overall size of the area of the posterior pole that is sampled as a factor that plays into image analysis.
