    2. Indiana University Receives NIH Grant for Optical Imaging of Photoreceptor Function and Structure

      Indiana University Receives NIH Grant for Optical Imaging of Photoreceptor Function and Structure
      Indiana University at Bloomington received a $323,968 2011 NIH grant to study optical imaging of photoreceptor function and structure.  This is part of a multiyear project that started in 2007 and ends in 2012. The principal investigator is Donald Miller. Below is a summary of that work. Human vision starts when photoreceptors collect and respond to light. Normal photoreceptor function and structure are essential for normal vision, yet techniques ...

    3. Adaptive optics and the eye (super resolution OCT)

      Adaptive optics and the eye (super resolution OCT)
      The combination of adaptive optics (AO) and optical coherence tomography (OCT) was first reported 8 years ago and has undergone tremendous technological advances since then. The technical benefits of adding AO to OCT (increased lateral resolution, smaller speckle, and enhanced sensitivity) increase the imaging capability of OCT in ways that make it well suited for three-dimensional (3D) cellular imaging in the retina. Today, AO–OCT systems provide ultrahigh 3D resolution ...

    4. Directional property of the retinal reflection measured with optical coherence tomography and wavefront sensing (Thesis)

      Directional property of the retinal reflection measured with optical coherence tomography and wavefront sensing (Thesis)
      The last thirty years have experienced tremendous advancement in our understanding of light-tissue interactions in the human retina. Nevertheless, major gaps remain, and our modeling of light return from the back of the eye continues to evolve. The objective of this thesis is to investigate one of these gaps, specifically that related to the directional property (angular dependence) of the retinal reflection and in particular that of cone photoreceptors. Directionality ...

    5. Devices And Methods For Polarization-Sensitive Optical Coherence Tomography With Adaptive Optics (Wo 2010/085618)

      Devices And Methods For Polarization-Sensitive Optical Coherence Tomography With Adaptive Optics (Wo 2010/085618)
      The present disclosure includes disclosure of devices, and methods to resolve microscopic structures. In at least one exemplary embodiment, a visualization apparatus comprises a source arm having a light source operable to emit a light beam, wherein the light beam defines a beam pathway, a reference arm comprising a reflecting surface positioned within the beam pathway, a sample arm comprising a wavefront sensor, an adaptive optics wavefront corrector, and a ...

    6. Imaging retinal nerve fiber bundles at ultrahigh-speed and ultrahigh-resolution using OCT with adaptive optics

      Imaging retinal nerve fiber bundles at ultrahigh-speed and ultrahigh-resolution using OCT with adaptive optics
      Ultrahigh speed line scan detectors based on CMOS technology have been recently demonstrated in ultrahigh resolution spectral-domain optical coherence tomography (UHR-SD-OCT) for retinal imaging. While successful, fundamental tradeoffs exist been image acquisition time, image sampling density, and sensitivity, all of which impact the extent of motion artifacts, visualization of fine spatial detail, and detection of faint reflections. Here we investigate these tradeoffs for imaging retinal nerve fiber bundles (RNFBs) using ...

    7. Cellular imaging of the living human retina

      Cellular imaging of the living human retina
      A device combining optical coherence tomography and adaptive optics can capture micron-scale 3D pictures of the retina. Viewing the retina through the eye's cornea and crystalline lens dates back to the time of Helmholtz, inventor of the ophthalmoscope. Ophthalmoscopes have advanced substantially since then and are now an indispensable non-invasive tool for diagnosis and treatment monitoring. While there are three principal types—conventional ophthalmoscopes, confocal scanning laser ophthalmoscopes (cSLOs ...

  2. About Donald T. Miller

    Donald T. Miller

    Donald Miller earned a B.S. in applied physics from Xavier University and a Ph.D. in optics from University of Rochester. This was followed by a National Research Council Research Associate position at Wright-Patterson Air Force Base in Dayton, Ohio. He joined the faculty at Indiana University School of Optometry in 1998 and currently holds the rank of Professor. Miller’s research focuses on the application of optical engineering and biomedical optics to the human eye. His group has pioneered the development of high-resolution optical systems for imaging the back of the eye based on the combined technologies of adaptive optics (AO) and optical coherence tomography (OCT). The cameras have opened a new window of opportunity to probe, noninvasively, the structure and function of the living retina at the cellular level in normal and diseased eyes in ways that have been traditionally limited to histology. He received a R&D; 100 Award for development of a MEMS-based Adaptive Optics Optical Coherence Tomography instrument in collaboration with colleagues at UC-Davis and Lawrence Livermore National Laboratory. Miller is actively involved in numerous optics and eye-related professional societies. He has chaired the OSA Adaptive Optics Topical Meeting three times and regularly serves on the program committee of the SPIE Ophthalmic Technologies Conference. He is a Fellow of OSA and SPIE.
