Study by David Huang and ARVO authors finds vision research pays for itself

Researchers have shown that optical coherence tomography (OCT) has saved Medicare $9 billion dollars by reducing the frequency of anti-vascular endothelial growth factor (anti-VEGF) injections used to treat patients with wet age-related macular degeneration (wet-AMD). Their results were published in the American Journal of Ophthalmology and announced publically at a Congressional briefing in Washington, D.C. The manuscript serves as the capstone of the ARVO public awareness campaign, “Telling the story of OCT”, an ARVO initiative to promote the value of vision research to policymakers, the press, patients and the general public.

The savings to Medicare, the U.S. health insurance program for citizens over 65 years old, is 21 times more than the $0.4 billion invested by the National Institutes of Health and the National Science Foundation over 20 years — suggesting that investments in vision research more than pay for themselves.

ARVO President Claude Burgoyne, MD, FARVO, of Devers Eye Institute, and coauthors Philip Rosenfeld, MD, PhD of Bascom Palmer Eye Institute and Eric Swanson, MS, co-inventor of OCT, presented the paper’s findings to legislators on Capitol Hill at an hour-long Congressional briefing cosponsored by the Alliance for Eye and Vision Research. Prior to the briefing, the three participated in advocacy visits with their Congressional delegations, which were hosted by the National Alliance for Eye and Vision Research (NAEVR). To help policymakers better understand the technology and its capabilities, an OCT instrument provided by Leica Microsystems was available at the briefing to scan the retinas of attendees.

Yali Jia, PhD Receives NIH Grant for Wide-Field and Projection-Resolved Optical Coherence Tomography Angiography in Diabetic Retinopathy

Yali Jia, PhD receives a 2017 NIH Grant for $487,587 for Wide-Field and Projection-Resolved Optical Coherence Tomography Angiography (OCTA) in Diabetic Retinopathy (DR). The program begins in 2017 and ends in 2021.

The OCTA technology used by previous studies is limited by the small fields of view (2.4-6 mm) and the projection artifacts in the deeper layers, which are caused by flowing blood cells in the more superficial vessels. The current proposal will overcome the previous limitations by improving both the hardware platform and software algorithms to obtain wide-field (WF) and projection-resolved (PR) OCTA.

  1. Develop wide-field OCT system for imaging peripheral retinal circulation. We have developed a 200-kHz swept-source optical coherence tomography (SS-OCT) system. This system is ready for use in clinical studies. We propose to further increase system speed and develop automatic registration and montage algorithms to create ultrawide-field OCTA.

  2. Improve the projection-resolved OCTA algorithm for imaging of retinal and choroidal plexuses. We have preliminarily demonstrated that separation of three retinal plexuses improved the detection of early vascular changes in DR. We will refine this algorithm and apply it to the WF-OCTA on the high-speed SS-OCT systems.

  3. Quantify neovascularization and nonperfusion areas using WF- and PR-OCTA in DR. We will further optimize the automated quantification of all relevant DR endpoints, including nonperfusion of all vascular layers, neovascularization, cyst volume, and retinal thickness maps on both commercial and custom OCT systems proposed in this study.

  4. Evaluate advanced OCTA for DR in clinical studies.

Celebrating 25 years of Optical Coherence Tomography

Co-invented by OHSU's Dr. David Huang 25 years ago, OCT technology helps detect and stop blindness

 

ARVO journal publishes special issue to commemorate 25th anniversary 

PORTLAND, Ore.– The Association for Research in Vision and Ophthalmology today published a special anniversary edition in their journal Investigative Ophthalmology & Visual Science with more than 70 articles to commemorate the 25th anniversary of the invention of Optical Coherence Tomography technology, co-invented by Oregon Health & Science University Casey Eye Institute's David Huang, M.D., Ph.D. while Huang was a Ph.D. student with James Fujimoto, Ph.D. at Massachusetts Institute of Technology.

OCT is the most commonly used ophthalmic diagnostic technology worldwide, with an estimated 30 million OCT imaging procedures performed every year.

"I am pleased to see how well the OCT technology has evolved over the past 25 years to help diagnose and treat the most common causes of blindness, age-related macular degeneration, diabetic retinopathy and glaucoma,” said Huang, Peterson Professor of Ophthalmology and Biomedical Engineering at OHSU Casey Eye Institute. "OCT use continues to grow exponentially in ophthalmology and other medical specialties, including cardiology, dermatology, neurology and gastroenterology.”

OCT has transformed the way ophthalmologists are able to diagnose, monitor and treat devastating eye diseases, and it has advanced drug discovery and development. The technology is particularly suitable for the early detection of glaucoma and macular degeneration, diseases that may cause significant damage prior to the appearance of symptoms. OCT is also widely used for diabetic macular edema, the leading cause of blindness in young patients.

"Dr. Huang's contribution to the field of ophthalmology has been tremendous and we are very fortunate to have such a brilliant mind here at Casey Eye Institute and in Oregon,” said David J. Wilson, M.D., director of the OHSU Casey Eye Institute and chair of the Department of Ophthalmology in the OHSU School of Medicine. "This anniversary is a perfect opportunity to celebrate OCT as a truly transformative medical technology. Such transformations do not occur often in medicine.”

OCT technology has evolved over the past 25 years with great advances in imaging speed and quality. Ophthalmologists can now study disease at the microscopic level without biopsy, and with complete patient comfort. For the first time, eye physicians can visualize and measure blood flow in the smallest of blood vessels, without the need to inject contrast agents. Non-invasive visualization and measurement of blood flow gives great insight into the cause and progression of eye disease.

Huang, who was recently ranked the 4th most influential figure in the world of ophthalmology by The Ophthalmologist PowerList 2016, runs the Center for Ophthalmic Optics and Lasers, or COOL Lab, at Casey Eye Institute which includes a team of top scientists from around the world who have been perfecting OCT technology for more than 15 years. Several members of the lab have contributed articles for the special issue in IOVS (see Related Content for links to articles).

"The special issue focused on Optical Coherence Tomography is a timely compendium of recent research papers that are using this technology that has reshaped our thinking about disease processes and drug mechanisms,” said Thomas Yorio, Ph.D., a fellow of ARVO and editor-in-chief at the ARVO journal IOVS. "The ability to utilize OCT and the advances in this imaging technique have allowed us to see sections of the eye in a vastly new way, making surgical procedures easier, clinical observations clearer and providing insight into new research areas. IOVS is excited to host this exciting special issue. Special thanks go to our contributing editors, Dr. Huang and Dr. Fujimoto.”

Key OHSU collaborators with Huang's lab include Ou Tan, Ph.D., John C. Morrison, M.D., Yali Jia, Ph.D., Winston Chamberlain, M.D., Ph.D., Steven Bailey, M.D., Thomas S. Hwang, M.D., and Douglas D. Koch, M.D. at Baylor College of Medicine in Houston.

ARVO Initiative

Subject: OCT public awareness campaign launched

Colleagues,

With so many of us reliant on government funding for our research, it is important to show the impact our work has on patients, policymakers and the general public. To spread awareness of our community’s contributions to public health, ARVO is launching the largest science communication project it has ever undertaken, called “Revealing the back of the eye with optical coherence tomography (OCT).”

The flagship product of this campaign is a series of videos featuring testimony from patients, clinicians and researchers. Topics cover how OCT improves the diagnosis and monitoring of diseases such as glaucoma, macular degeneration, retinopathy of prematurity and diabetic retinopathy. The technology’s initial support from government funding and potential future applications — diagnosing neurological diseases like Alzheimer’s, improving surgical outcomes in the operating room and application in telemedicine — are highlighted as well.

In addition to the videos, several other resources have been developed:

 

This two-year project would not have been possible if it wasn’t for the support of the ARVO Board of Directors. I am also grateful for the guidance provided by the OCT Advisory Panel, a group of the leading OCT researchers who helped guide the direction and accuracy of the initiative. Finally, I’d like to thank the ARVO staff who dedicated a significant amount of their time ensuring this project crossed the finish line.
