    9. Repeatability Using Automatic Tracing with Canon OCT- HS100 and Zeiss Cirrus HD-OCT 5000

      Repeatability Using Automatic Tracing with Canon OCT- HS100 and Zeiss Cirrus HD-OCT 5000
      Background Optical coherence tomography (OCT), can be used in clinical practice to provide high resolution cross-sectional images of the retina, optic disc and macula structure. These measurements can be useful for early detection, diagnosis, monitoring and treatment guidance for retinal diseases. Therefore, repeatability of measurements in OCT is of great importance. Methods Macula and optic disc parameters from the right eye of 30 healthy subjects were obtained twice with the ...

    10. Optical Coherence Tomography Industry Has Provided Well Over 20,000 Person-Years of Direct Employment

      Optical Coherence Tomography Industry Has Provided Well Over 20,000 Person-Years of Direct Employment
      The field of Optical Coherence Tomography (OCT) has grown dramatically since its discovery in the early 1990s. 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 ...
