"In- and On-the-Eye Low Vision Telescopes: A Critical Evaluation"

Dr. Eli Peli

Dr. Eli Peli is the Moakley Scholar in Aging Eye Research at Schepens Eye Research Institute and Professor of Ophthalmology at Harvard Medical School. He is also the director of the Vision Rehabilitation Service at the Tufts Medical Center in Boston. Dr. Peli is a Fellow of the American Academy of Optometry, the Optical Society of America, the Society for Information Display, and the International Society of Optical Engineering. He has published more than 200 peer reviewed scientific journal papers and has been awarded 10 US patents. Among numerous other awards, Dr. Peli received the Glenn A. Fry Lecture Award, the William Feinbloom Award, and the Charles F Prentice Medal from the American Academy of Optometry. Dr. Peli's principal research interests are image processing in relation to visual function as well as clinical psychophysics in low vision rehabilitation, image understanding, and display-vision interaction.

"Tablet-Based Visual Field Screening – There Really is an App for That”"

Chris A. Johnson, PhD, DSc
Department of Ophthalmology and Visual Sciences
University of Iowa Hospitals and Clinics

Chris A. Johnson is a Professor in the Department of Ophthalmology and Visual Sciences at the University of Iowa Hospitals and Clinics, Iowa City, Iowa, USA. His primary research interests are related to the development and evaluation of non-invasive diagnostic test procedures (perimetry, photography, imaging) for glaucoma and other ocular and neurologic disorders, with secondary interests in occupational vision requirements, vision and transportation safety, and oculomotor adjustments. He has also been involved in many multicenter clinical trials and the development and maintenance of visual field reading centers for quality control, evaluation and interpretation of perimetric outcome measures. Dr. Johnson has received many honors from Ophthalmologic, Optometric and institutional sources, has received a considerable amount of research funding, and has authored more than 425 journal publications and book chapters throughout his career.

"Biomarkers for Microvascular Complications of Diabetes"

Dr. Barbara Klein
University of Wisconsin School of Medicine and Public Health

Dr. Barbara E. K. Klein is an experienced ophthalmologist and epidemiologist, and has dedicated more than 30 years to investigating age-related eye diseases. She is coprincipal investigator of the Wisconsin Epidemiologic Study of Diabetic Retinopathy (WESDR), a study of retinopathy and other ocular and systemic complications of diabetes. She collaborated with Dr. Ronald Klein on the study design and logistics of the first and all subsequent examinations, and has been an author or co-author on the vast majority of reports and manuscripts originating from the study. She is also coprincipal investigator of the Beaver Dam Eye Study (BDES), a study of ocular diseases of aging. The BDES has identified and quantified important risk factors for age-related macular degeneration and other eye diseases in older persons. Its findings have been instrumental in furthering understanding of the etiology of these diseases and focusing approaches to preventive interventions. She has been involved in developing and implementing protocols for grading eye disease, analyzing data, and collaborating on papers for the National Health and Nutrition Survey (NHANES), Atherosclerosis Risk in Communities (ARIC) study, Multi-Ethnic Study of Atherosclerosis (MESA), Los Angeles Latino Eye Study (LALES) and other population-based studies. She has also collaborated with numerous investigators around the world to study the epidemiology and genetics of diabetic and hypertensive retinopathy, diabetic nephropathy, chronic kidney disease, and age-related eye diseases.

"Functional Imaging of Single Cells in the Living Eye"

Dean for Research in Arts, Science, and Engineering
Director, Center for Visual Science
William G. Allyn Professor of Medical Optics

The correction of the eye’s aberrations with adaptive optics (AO) has made it possible to image the normal and diseased retina of the living eye at microscopic resolution. Recent developments in the deployment of this technology, many of which combine AO and other imaging modalities with the goal of obtaining not only structural but also functional information at a cellular and sometimes subcellular spatial scale, will be described. The value of this approach with examples including single and two-photon fluorescence imaging of individual retinal cells will be illustrated, which allows us to optically probe the electrical signals the retina sends to the brain as well as molecular events in photoreceptors that would otherwise be invisible. It may be that these high resolution imaging tools, combined with recent advances in our ability to record from and control neurons with light, will eventually help complete our understanding of the computations the retina performs that allow us to see and also help to restore vision in the blind.
