Optical coherence tomography (OCT) has transformed the landscape of eye care since its inception. This groundbreaking imaging technique, which allows for noninvasive, high-resolution visualization of biological tissues, was developed by clinician-scientist David Huang, who has become a pivotal figure in ophthalmic technology. With approximately 40 million OCT procedures performed annually, its applications extend beyond ophthalmology to assess conditions like coronary artery disease by mapping tissue structures in great detail.
Huang’s journey began at MIT, where he pursued electrical engineering, inspired by a desire to blend engineering principles with medical advancements—following in the footsteps of his father, a family doctor. His research during the Harvard-MIT Program in Health Sciences and Technology led to the conception of OCT. Under the mentorship of James Fujimoto, Huang explored ultrafast lasers and interferometry, enabling precise measurements of corneal and retinal thickness. The novel imaging modality was born when Huang, Fujimoto, and Eric Swanson collaborated to apply these techniques in biological contexts, ultimately publishing their pioneering work in the journal Science in 1991.
Fast forward to today, Huang continues to innovate as the director of research at the Casey Eye Institute at Oregon Health and Science University. His ongoing work includes developing advanced techniques such as OCT angiography and optoretinography, which enhance our understanding of blood flow and retinal responses. Additionally, he co-founded GoCheck Kids, a digital platform aimed at improving pediatric eye screenings. Huang attributes his success in innovation to his unique position at the intersection of medicine and engineering, highlighting the advantage of having expertise in both realms to tackle real-world clinical challenges.
