| Summary: | Optical coherence tomography angiography (OCTA) is a new, non-invasive imaging technique that generates angiography images in a matter of seconds. Since it detects vascular compromise even before clinical picture sets in , it is a very useful tool in the diagnosis of retinal vascular pathology.In this review we introduce the technology and compare it with the current angiographic gold standards, fluorescein angiography (FA) and indocyanine green angiography (ICGA). Finally we summarize its potential application to retinal vascular diseases..Its current limitations include a relatively small field of view, inability to show leakage & motion artefacts.Published studies hint at OCTA's potential efficacy in the evaluation of common ophthalmologic diseases such as age related macular degeneration (AMD), diabetic retinopathy, artery and vein occlusions, and glaucoma. |
