1. Estimating Public and Patient Savings From Basic Research—A Study of Optical Coherence Tomography in Managing Antiangiogenic Therapy
  
  Explore American Journal of Ophthalmology Dec 7 2017 Ophthalmology
  
  Purpose To compare patient and Medicare savings from the use of optical coherence tomography (OCT) in guiding therapy for neovascular age-related macular degeneration (nvAMD) to the research investments made in developing OCT by the National Institutes of Health (NIH) and the National Science Foundation (NSF). Design Observational cohort study. Methods Main outcome measures were spending by Medicare as tracked by Current Procedural Terminology codes on intravitreal injections (67028), retinal OCT imaging (92134), and anti–vascular endothelial growth factor (anti-VEGF) treatment–specific J-codes (J0178, J2778, J9035, J3490, and J3590).

2. Feature Of The Week 10/1/2017: Optical Coherence Tomography: from Healthcare Idea to Healthcare Impact.
  
  Explore Optical Coherence Tomography News Oct 1 2017
  
  The commercialization and growth of OCT which has occurred over the past 25 years has been highly impactful scientifically, clinically, and economically. Many factors have helped drive this success starting with the clinical need for new cost-effective high-resolution minimally-invasive imaging solutions for various diagnostic and therapeutic applications. But equally important to this success was the intertwined role of researchers, engineers, clinicians, professional societies, government agencies, government funding, regulatory bodies, entrepreneurs, venture capitalists, and small and large corporate entities within the biomedical optics industry and other industries. This talk will review some of the history of the commercialization of OCT and ...

3. The ecosystem that powered the translation of OCT from fundamental research to clinical and commercial impact [Invited]
  
  Explore OSA | OSA Publishing Feb 22 2017
  
  25 years is a relatively short period of time for a medical technology to become a standard of care impacting the treatment of millions of people every year. Yet 25 years ago there were no OCT companies, no OCT products, no OCT markets, and only one journal article published using the term OCT (optical coherence tomography). OCT has had a tremendous scientific, clinical, and economic impact on society. Today, it is estimated that there are ~30 Million OCT imaging procedures performed worldwide every year and the OCT system market is approaching $1B per year. OCT has helped diagnose patients with ...

  Disclosed herein are optical integration technologies, designs, systems and methods directed toward Optical Coherence Tomography (OCT) and other interferometric optical sensor, ranging, and imaging systems wherein such systems, methods and structures employ tunable optical sources, coherent detection and other structures on a single or multichip monolithic integration. In contrast to contemporary, prior-art OCT systems and structures that employ simple, miniature optical bench technology using small optical components positioned on a substrate, systems and methods according to the present disclosure employ one or more photonic integrated circuits (PICs), use swept-source techniques, and employ a widely tunable optical source(s).

  Explore IOVS Journal Jul 17 2016
  
  This review was written for the special issue of IOVS to describe the history of optical coherence tomography (OCT) and its evolution from a nonscientific, historic perspective. Optical coherence tomography has become a standard of care in ophthalmology, providing real-time information on structure and function – diagnosing disease, evaluating progression, and assessing response to therapy, as well as helping to understand disease pathogenesis and create new therapies. Optical coherence tomography also has applications in multiple clinical specialties, fundamental research, and manufacturing. We review the early history of OCT describing how research and development evolves and the important role of multidisciplinary collaboration ...

  Optical coherence tomography has been an unqualified success in the area of ophthalmology. As recently noted by OCT pioneer Dr. Carmen Puliafito, “OCT has revolutionized the treatment of eye diseases on a global basis and it is now routinely used to make clinical decisions about treating patients with blinding diseases such as macular degeneration, diabetic retinopathy, and glaucoma”. Over the past decade the market for ophthalmic OCT systems has grown tremendously and is now over $300M/year; there are ~14 companies making ophthalmic OCT instruments and more on the way; new impressive product features continue to be rolled out; nearly ...

  Just this past May it seemed the Ontario Government had angered some doctors and patients by reducing the ophthalmic OCT reimbursment rate from about $63 to $25. This set off articles in the press like this one " Doctors and patients upset over Ontario gov't cuts to critical eye exams " where it was expressed by some that this was not in the best interest of Ontario, doctors, or patients. It now seems that this reimbursement has again changed as detailed in this article " Ontario government reaches deal with doctors " where it is quoted that " The optical coherence tomography fee, which ...

  Patents are obviously an important component of the OCT technology market place. Patents and the motives to file them have many roles. The motive for academics can be either to help enable a startup company the professor or student is involved in or to seek a share in the royalty fees by licensing to a company they are not involved in.[footnote 1] Many academics that start companies have licensed patents they authored from their institution, usually under exclusive terms. Exclusive fundamental patents can be a key factor in solidifying equity financing from investors. In addition, patents can serve as ...

15. Extracting and compensating dispersion mismatch in ultrahigh-resolution Fourier domain OCT imaging of the retina
  
  Explore opticsinfobase.org Oct 29 2012
  
  We present a numerical approach to extract the dispersion mismatch in ultrahigh-resolution Fourier domain optical coherence tomography (OCT) imaging of the retina. The method draws upon an analogy with a Shack-Hartmann wavefront sensor. By exploiting mathematical similarities between the expressions for aberration in optical imaging and dispersion mismatch in spectral / Fourier domain OCT, Shack-Hartmann principles can be extended from the two-dimensional paraxial wavevector space (or the x-y plane in the spatial domain) to the one-dimensional wavenumber space (or the z-axis in the spatial domain). For OCT imaging of the retina, different retinal layers, such as the retinal nerve fiber layer ...

  Figure 1 shows an example of the dramatic growth in OCT papers since the first OCT paper by Huang, et al in 1991. Table 1 shows the data in more detail. A few things are very obvious, including that the rate of growth of OCT publications is dramatic (~200 papers/year) and the publications are dominated by ophthalmology, followed by general technology, and cardiology. The legend on the right hand side of the figure shows the number of cumulative publications by subject area from 1991 to 2012. In this analysis only title and abstract were considered.

  Duke University Received a 2013 a NIH Grant for $384,751 on Computer Aided Classification of Diabetic Macular Edema. The principal investigator is Sina Farsiu. The program began in 2012 and ends in 2017. Below is a summary of the work. There are currently no well-established methods to identify and evaluate the mechanisms underlying diabetic macular edema (DME) pathobiology, one of the leading causes of blindness among working-age Americans. As such, the development of pathophysiology-specific therapeutic agents for DME is limited, and the selection of therapies personalized for individual patients remains subjective. Our long-term goal is to develop automated methods ...

  Long gone are the days when a new medical product could be easily introduced based solely on improved patient outcomes. To optimize the probability of success, a new product now needs to demonstrate that it can both improve patient outcomes and reduce costs. To the clinical practice manager, an attractive product will need to recoup its cost in the near term and generate revenues in a predictable and easily quantifiable manner, in addition to improving the quality of care. Optical coherence tomography has been an unqualified success in ophthalmology, where it is in daily use worldwide. There are tens of ...
