Angio-OCT is a novel diagnostic technique that allows visualization of the retinal circulation without the use of intravenous contrast; simultaneously, the different capillary networks of the retina and choroid can be seen. The vessels of the central 3mm, 6mm and 8mm of the retina can be visualized, as well as the circulation of the optic nerve head.
Applications of Angio-OCT
Angio-OCT has multiple applications in macular vascular pathology, optic nerve and choroidal pathology. For example, it allows studying the vasculature in diseases such as neovascular macular degeneration, diabetic retinopathy, macular edema and pachychoroidal diseases.
Angio-OCT can be used to observe areas of non-perfusion, and also to delimit the avascular zone of the fovea.
Advantages of Angio-OCT
Angio-OCT is a minimally invasive and very fast technique, which can be performed whenever the transparency of the ocular media allows it. It allows early detection of prevalent diseases, such as diabetic retinopathy, and is repeatable over time.
Risks of Angio-OCT
Unlike conventional fluorescein angiography, Angio-OCT has no risk, and is infinitely more comfortable and safer for the patient.
