A TVST review has explored the significant advancements made in optical coherence tomography angiography (OCTA) since the modality was first introduced into clinical practice in 2015. In the last decade, OCTA has revolutionized eye care by providing high-resolution images of microvascular structures, enabling early detection and monitoring of conditions such as diabetic retinopathy, macular degeneration, and glaucoma.
Key technological improvements considered by the Casey Eye Institute researchers include the expanded field of view allowed by newer wide-field OCTA technologies; advances in swept-source lasers and Fourier domain processing that have significantly improved imaging speed and resolution; AI-based models that can be used to analyze and interpret OCTA data; and the development of handheld OCTA devices.
All of these advancements make OCTA a powerful tool for early disease detection, treatment monitoring, and research into retinal conditions, the authors say. The combination of faster imaging, AI-assisted analysis, and wider field capabilities has made OCTA more accessible and practical for everyday clinical use. The review observes that, as imaging technology continues to evolve, OCTA can be expected to play an even more crucial role in research and clinical technology.
