Webinar Series: OSA Applications of Visual Science Webinar

With this Webinar we intend to provide background for the understanding of the human eye and visual system and to show how such knowledge can be used at the forefront of science to analyze the eye, the visual system and for ultrahigh resolution diagnostics of the human eye.

  • Prof. Melanie Campbell (Department of Physics, University of Waterloo, Canada); an expert in the optics and aberrations of the human eye. 
  • Prof. Pablo Artal (LOUM, Universidad de Murcia, Spain); an expert in adaptive optics for the analysis of the human eye.
  • Prof. Stephen A. Burns (School of Optometry, Indiana University, USA); an expert in retinal imaging and in photoreceptor analysis.

Webinar Description:
  • The refractive properties of the eye will be covered and examples will be given of how these can be overcome. This is beneficial to vision and to ophthalmic imaging and diagnostics of the eye and retina.
  • Adaptive optics technologies and correction procedures will be described.
  • Imaging applications that allow visualization of the retinal photoreceptors and blood flow will be discussed in relation to diagnostics and in relation to visual function. 

What You Will Learn/Seminar Objectives
  • Monochromatic and chromatic aberrations of the eye
  • Adaptive optics for the eye and vision
  • Retinal analysis and photoreceptor optics

Who Should Attend
  • Anyone interested in learning about aberrations of the eye, their impact on vision and ophthalmic imaging. These limitations may be overcome with refractive corrections and adaptive optics that not only provide better vision or improved retinal imaging, but also can be utilized to explore the optics of both the healthy eye and eyes with disorders.
  • Students and researchers with an interest in ophthalmic technologies and the eye.
  • Ophthalmic industry employees and clinicians who wish to increase their understanding of the human eye and the technical possibilities currently available to explore the eye and retina.

The webinar will be targeted for beginners and intermediate researchers towards the specialists.

A Year in Visual Optics: Understanding the Human Eye & Visual Systems

Dr. Melanie C. W. Campbell is Professor in the Department of Physics and Astronomy in University of Waterloo, Canada, and is cross-appointed to the School of Optometry and Vision Science. She obtained a B.Sc. degree in Chemical Physics from the University of Toronto and an M.Sc. degree in Physics from the University of Waterloo. An interest in the optical properties of the eye led to a Ph.D. from the Australian National University awarded jointly by the John Curtin School for Medical Research and the Research School of Physical Sciences and a 2 years postdoctoral fellowship at CSIRO in Australia. A University Research Fellowship from the Natural Sciences and Engineering Research Council of Canada enabled Dr. Campbell to join the University of Waterloo. She pursues research in optics of the eye, accommodation, presbyopia, ophthalmic corrections and ophthalmic diagnostic instruments. Her current research interests include defining the quality of the optical image formed on the retina; studying the optical properties of the crystalline lens and eye during development and in the older eye and integrating adaptive optics and polarization methods into instruments which image the rear of the eye. Her basic research led to improved quality of clinical images of the fundus of the eye. The Waterloo confocal scanning laser ophthalmoscope that was developed by Dr. Campbell's group gave the first live images of the cones of the human eye. She is interested in improved diagnostic imaging of ocular and systemic diseases and on light based ocular therapies. Dr. Campbell is a Fellow of the Optical Society of America, a Fellow of the Institute of Physics (UK), holds an honorary Professional Physicist designation from and is a former President of the Canadian Association of Physicists. Campbell was also a co-founder of Biomedical Photometrics Inc, now Huron Technologies. She received the 2004 Rank Prize in Optoelectronics for her work on the gradient of refractive index in the crystalline lens, cited as "an initial idea (that) has been carried through to practical applications that have, or will, demonstrably benefit mankind." 

Professor Pablo Artal is the founder and director of the Laboratorio de Optica (LOUM) at Universidad de Murcia, Spain. He received his M.Sc. degree in Physics from the University of Zaragoza, Spain, and the Ph.D. degree in Physics (Optics) from the University Complutense of Madrid in 1988. He was a post-doctoral fellow at the Institut d'Optique, Orsay, France in 1989-90 and a senior researcher at the Instituto de Optica (CSIC) in Madrid from 1990 to 1994. Since 1994, he is full Professor of Optics at the University of Murcia, Spain. He spent several periods doing collaborative research in laboratories in Europe, Australia and USA. He is a fellow member of the OSA and ARVO (gold category). He received the prestigious 2013 Edwin H Land medal award in recognition of his scientific contributions to the advancement of diagnostic and correction alternatives in visual optics. He is the recipient of the exclusive "European Research Council advanced grant" in 2013. He has published more than 150 reviewed papers that received 5500 citations (h-index: 41), presented more than 150 invited talks in international meetings and around 120 seminars in different research institutions. He is also a co-inventor of 18 international patents in the field of Optics and Ophthalmology. He has pioneered a number of highly innovative advances in the methods for studying the optics of the eye and has contributed substantially to our understanding of the factors that limit human visual resolution. Dr. Artal is a pioneer in exploring the human eye with new technologies and designed new ophthalmic corrections. Several of his proposed solutions and instrument are currently in use in the clinical practice. For example, he co-invented intraocular lenses correcting for the corneal spherical aberration that provides improved quality of vision to millions of patients over the world. Dr. Artal is the founder of Voptica SL a spin-off company developing the concept he invented of adaptive optics vision analyzers. He has been the mentor of many graduate and post-doctoral students. His personal science blog (http://pabloartal.blogspot.com) is followed by readers, mostly graduate students and fellow researchers, from around the world. He has been editor of the Journal of the Optical Society of America A and the Journal of Vision.

Professor Stephen A. Burns is Associate Dean for Graduate Programs in the School of Optometry, Indiana University, USA. He received his Ph.D. in biophysics from The Ohio State University in 1977. He held academic positions in ophthalmology at the University of Pittsburgh and Harvard University Medical School. He was an associate scientist at the Eye Research Institute 1987–1992 and a senior scientist 1992–2004. He also served as associate director of Schepens Eye Research Institute. His memberships include The Optical Society of America (where he has been a fellow since 1993) and the Association for Research in Vision and Ophthalmology. Professor Burns has served on the Visual Science Study Section, and is a past editor of the Journal of the Optical Society of America, and the 2010 recipient of the Optical Society of America's Tillyer Medal
