Utility of Optical Coherence Tomography Angiography (OCTA) in Granulomatosis With Polyangiitis. [PDF]
Cureus, 2022 A 61-year-old male presented with visual loss in the left eye. A CT scan of the chest revealed multiple lung cavities in both lungs. He had a positive C-ANCA suggestive of granulomatosis with polyangiitis. There were multiple areas of superficial retinal opacification in the right eye and anterior ischemic optic neuropathy in the left eye.

A review of optical coherence tomography angiography (OCTA) [PDF]
International Journal of Retina and Vitreous, 2015 Optical coherence tomography angiography (OCTA) is a new, non-invasive imaging technique that generates volumetric angiography images in a matter of seconds. This is a nascent technology with a potential wide applicability for retinal vascular disease. At present, level 1 evidence of the technology's clinical applications doesn't exist.
