      Development of Multimodal Optical System Guided by Optical Coherence Tomography (Thesis)
      The goal of this dissertation is to develop multimodal light scattering techniques using optical coherence tomography (OCT) to improve clinical diagnosis. OCT is a noninvasive optical imaging technique that utilizes low coherence interferometry to detect reflected and scattered light from a sample to produce depth resolved images. OCT is an emerging technology for a wide range of biomedical applications, with its largest impact in the field of ophthalmology to assess ...

      Hyperreflective Vitreous Opacities on Optical Coherence Tomography in a Patient With Bilateral Retinoblastoma
      An investigational, portable spectral-domain optical coherence tomography (SD-OCT) unit revealed small hyperreflective opacities in both eyes of a patient with bilateral retinoblastoma. There was no evidence of vitreous seeding on ophthalmoscopy of either eye. Although the opacities may initially raise concern for potential vitreous seeding, this report suggests alternate potential etiologies for such opacities, which were also seen on imaging of a cohort of normal eyes in pediatric patients.

      Current role of optical coherence tomography angiography: Expert panel discussion
      Optical coherence tomography (OCT) angiography is a promising technique that provides depth resolved images of blood flow in the retina and choroid with levels of detail far exceeding that obtained with older forms of imaging and offers several advantages over conventional angiography to visualize the chorioretinal vasculature in a rapid and noninvasive manner. However, as with any evolving imaging technique, there are ongoing challenges in terms of need for new ...

      Depth-Based, Motion-Stabilized Colorization of Microscope-Integrated Optical Coherence Tomography Volumes for Microscope-Independent Microsurgery
      Purpose : We develop and assess the impact of depth-based, motion-stabilized colorization (color) of microscope-integrated optical coherence tomography (MIOCT) volumes on microsurgical performance and ability to interpret surgical volumes. Methods : Color was applied in real-time as gradients indicating axial position and stabilized based on calculated center of mass. In a test comparing colorization versus grayscale visualizations of prerecorded intraoperative volumes from human surgery, ophthalmologists ( N = 7) were asked to identify retinal ...

      The overall five-year goals of the project are to develop novel technology to provide actionable new information through provision of live volumetric imaging during surgery, improving surgical practice and outcomes. The investigators believe this technology will enable novel ophthalmic and other microsurgeries not possible due to current limitations in surgical visualization.

      The authors report the widefield montage swept-source optical coherence tomography angiography (OCTA) findings in a 36-year-old male with sympathetic ophthalmia and illustrate the presence of multiple small areas of choriocapillaris flow voids that likely correspond to areas of choriocapillaris ischemia. Using sequential imaging, the authors observed that these flow voids improved following initiating of steroid and immunosuppressive therapy and almost completely resolved following 6 months of therapy with corresponding improvement ...

      Medical devices at the point of care allow clinicians to do what they do best: determine a patients exact condition and a course of treatment. These technologies work best when they fit seamlessly into the provider-patient workflow without a steep learning curve or worry about the underlying scientific principles, and without the high cost seen for so many medical technologies. Optical coherence tomography (OCT) is an imaging technology that has ...
