On Apr. 24, 2015, researchers led by David Huang, M.D., Ph.D. at Oregon Health Sciences University’s (OHSU) Casey Eye Institute announced they had developed a technology – optical coherence tomography (OCT) angiography – to better diagnose and manage the leading causes of blindness in the U.S. – retinal vascular diseases such as macular degeneration, diabetic eye disease, and glaucoma.

OCT provides a more precise and less invasive alternative to conventional dye-based retinal angiography used for screening and monitoring. The study results were published in the Proceedings of the National Academy of Sciences.
