    1. OCT upgrade may help improve glaucoma detection

      OCT upgrade may help improve glaucoma detection

      Heidelberg Engineering says the FDA approved its new upgrade for the Spectralis OCT platform , the Glaucoma Module Premium Edition, which allows better diagnostic accuracy through objective measurement parameters. Driven by a proprietary new technology called the Anatomic Positioning system, the module creates detailed maps of each patient’s eyes using the center of the fovea and the center of Bruch’s membrane opening as orienting landmarks. All subsequent scans are automatically aligned to the unique map, allowing for comprehensive and highly precise monitoring of the optic nerve head, retinal nerve fiber layer, and ganglion cell layer over time. The tool ...

      New Devices for Posterior Segment Imaging-Spectral Domain OCT in Infants

      Macular disease in children is routinely recorded in drawings and color photographs, and less commonly through angiography performed under anesthesia.  Technhiques used to evaluate function include preferential looking, figure or letter recognition, visual evoked potentials, and electroretiograms.

    3. Ebola survivors bear unique retinal scarring

      Ebola survivors bear unique retinal scarring

      Researchers from the University of Liverpool have discovered that an estimated 15% of Ebola survivors have a retinal scar that appears specific to the disease . “The distribution of these retinal scars or lesions provides the first observational evidence that the virus enters the eye via the optic nerve to reach the retina in a similar way to West Nile virus. Luckily, they appear to spare the central part of the eye so vision is preserved,” said Paul Steptoe, MD, an ophthalmologist at the Royal Liverpool Hospital who performed the ocular examinations. “Our study also provides preliminary evidence that in survivors ...

    4. Blind Boy Sees After Gene Therapy

      Blind Boy Sees After Gene Therapy

      Creed Pettit has been slowly going blind since the day he was born. Creed has a rare genetic condition called Leber congenital amaurosis (LCA) and it makes it impossible for him to see except in bright light. As an infant, sunset would bring on fits of colic that were soothed only by the glow of street lights or the brightly-lit Publix grocery store. As he grew older, Creed managed to find his way with lamps and high-powered flashlights and he learned to read with the help of special lighting. By age 9, he carried a flashlight everywhere, including his school ...

    5. Anterior segment imaging useful for evaluating angle closure

      Anterior segment imaging useful for evaluating angle closure

      This paper describes the role of anterior segment imaging in angle closure diagnosis and management, and explores the possible advantages of this approach over the current standard of gonioscopy. Study design This review summarizes the current literature on the use of anterior segment optical coherence tomography (AS-OCT) and ultrasound biomicroscopy (UBM) to assess the anterior chamber angle in patients with primary angle closure disease. Outcomes With gonioscopy as a reference for narrow angle detection, AS-OCT has a diagnostic sensitivity of 64% to 100% and a specificity of 55% to 100%, depending on the study population and narrow angle cutoffs. Short- ...

    6. OCT: Past, Present and Future

      OCT: Past, Present and Future

      In this interview, Dr. Joel Schuman discusses his keynote lecture for the 2017 New Horizons Forum, offering his perspective on the past, present and future of optical coherence tomography (OCT). Dr. Schuman was a member of the team that developed OCT about 20 years ago. As Dr. Schuman and coworkers continue to improve OCT, he sees opportunities for growth in intraoperative OCT, and he is excited about the possibilities of using image-guided robotic surgery alongside 3D OCT.

    7. Femtosecond laser-assisted incisions minimize wound healing response

      Femtosecond laser-assisted incisions minimize wound healing response

      Study design The study included 58 eyes with 2.2-mm femtosecond laser-assisted biplanar clear corneal incisions, and 34 eyes with 2.2-mm manual single-plane clear corneal incisions. All patients were evaluated on postoperative day 1, week 1, month 1 and month 3 using spectral-domain OCT (RTVue-XR Avanti, Optovue Inc). The authors assessed the rates of Descemet's membrane detachment, posterior wound gape and posterior wound retraction in each group. Outcomes Compared with the control group, the femtosecond group had a lower rate of posterior wound gape on day 1 and a lower rate of Descemet's membrane detachment at all ...
