The imaging technology known as optical coherence tomography, or OCT, is commonly used to diagnose and manage eye diseases that can cause blindness. This en face image, displayed in a frontal view, is from an OCT angiography scan of an eye with wet age-related macular degeneration, and focuses on the retina, light-sensitive tissue in the back of the eye. Abnormal blood vessel growth is shown in yellow, while normal retinal blood vessels are purple. (OHSU/Yali Jia)
