3. Characterization of Corneal Donor Tissue Lesions by Anterior Segment Optical Coherence Tomography Compared With Eye Bank Technician Slit-Lamp Examination
  
  Explore LWW Online Jul 31 2018 Ophthalmology
  
  Purpose: To compare anterior segment spectral-domain optical coherence tomography (OCT) with eye bank technician slit-lamp examination (SLE) in characterizing lesions in donor corneas. Methods: Twenty-nine donor corneas identified by eye bank technicians to have opacities or lesions potentially representing pathologic findings affecting the stroma were evaluated through the use of technician SLE, SLE photography, and OCT. Technicians were tasked with describing the lesion, estimating the lesion depth, and photographing their ...

6. Macular Features on Spectral-Domain Optical Coherence Tomography Imaging Associated With Visual Acuity in Coats' Disease
  
  Explore IOVS Journal Jul 4 2018 Ophthalmology
  
  Purpose : To investigate the association between macular features on spectral-domain optical coherence tomography (SD-OCT) and visual acuity (VA) in Coats' disease. Methods : Thirty-nine eyes (39 patients) with SD-OCT from January 1, 2008 to December 31, 2016 were reviewed for SD-OCT features. Central subfield (CSF) SD-OCT findings were analyzed relative to VA (logarithm of the minimum angle of resolution) at baseline and final visit (when follow-up 6 months) and across visits ...

8. Feature of the Week 06/24/2018: Duke University Researchers Show Exciting Advances in Live OCT Volumes in Immersive Virtual Reality
  
  Explore Optical Coherence Tomography News Jun 24 2018
  
  Virtual reality (VR) head-mounted displays are an attractive technology for viewing intrasurgical optical coherence tomography (OCT) volumes because they liberate surgeons from microscope oculars. We demonstrate real-time, interactive viewing of OCT volumes in a commercial HTC Vive immersive VR system using previously reported ray casting techniques. Furthermore, we show interactive manipulation and sectioning of volumes using handheld controllers and guidance of mock surgical procedures in porcine eyes exclusively within VR ...

12. Clinical Use of Optical Coherence Tomography Angiography in Diabetic Retinopathy Treatment Ready for Showtime?
  
  Explore The JAMA Network May 29 2018 Ophthalmology
  
  Diabetic macular edema (DME) and proliferative diabetic retinopathy (PDR) are the 2 advanced stages of diabetic retinopathy (DR) that are the main causes for visual loss in patients with diabetes. Both DME and PDR can be readily diagnosed with clinical examination and, increasingly, by the noninvasive use of optical coherence tomography. However, another, less commonly recognized cause of visual loss in patients with diabetes is diabetic macular ischemia (DMI) in ...

13. Deep longitudinal transfer learning-based automatic segmentation of photoreceptor ellipsoid zone defects on optical coherence tomography images of macular telangiectasia type 2
  
  Explore OSA | OSA Publishing May 22 2018 Ophthalmology
  
  Photoreceptor ellipsoid zone (EZ) defects visible on optical coherence tomography (OCT) are important imaging biomarkers for the onset and progression of macular diseases. As such, accurate quantification of EZ defects is paramount to monitor disease progression and treatment efficacy over time. We developed and trained a novel deep learning-based method called Deep OCT Atrophy Detection (DOCTAD) to automatically segment EZ defect areas by classifying 3-dimensional A-scan clusters as normal or ...

  Purpose : We advance studies of subretinal treatments by developing a microscope-integrated optical coherence tomography (MIOCT) image-based method for measuring the volume of therapeutics delivered into the subretinal space. Methods : A MIOCT image-based volume measurement method was developed and assessed for accuracy and reproducibility by imaging an object of known size in model eyes. This method then was applied to subretinal blebs created by injection of diluted triamcinolone. Bleb volumes obtained ...

  Explore LWW Online Mar 20 2018 Ophthalmology
  
  Purpose: In this study, we hypothesized that thickening along the major arcade vessels is a noninvasive marker of inflammation in eyes with birdshot retinochoroiditis (BRC). Methods: In this single-center retrospective study, patients with BRC were identified. Perivascular thickening was categorized as mild, moderate, or severe, based on a set of standard reference retinal thickness maps derived from representative spectral domain optical coherence tomography volume scans. The assigned perivascular severity thickness ...
