Abstract :

Statement of the Problem: Optical Coherence angiography (OCTA) is a new noninvasive imaging technique that employees motion contrast imaging to high resolution volumetric blood flow information generating angiographic images in a matter of seconds. Published studies hint at OCTAâ??s potential efficacy in the evaluation of common ophthalmologic diseases such age related macular degeneration (AMD), diabetic retinopathy, artery and vein occlusions, and glaucoma. OCTA can detect changes in choroidal blood vessel flow and can elucidate the presence of choroidal neovascularization (CNV) in a variety of conditions but especially in AMD. The purpose of this paper is to elucidate the main applications and potential limitations comparing to Fluorescein angiography (FA). Methodology & Theoretical Orientation: A review of the recent publications regarding this topic was done to define the applications and possible limitations of this new technology. Findings: Optical Coherence angiography (OCTA) main applications was diabetic retinopathy, choroidal Neovascularization due to AMD, differential diagnosis with retinal telangiectasia and retinal vein occlusions. The main limitations was: restricted visual field, Inability to show leakage, artifacts during acquisition and the device are currently expensive. Conclusion & Significance: This technology, despite some limitations, offer a non-invasive option of visualization of the retinal vasculature in detail. Recent Publications 1.
