Oxygen in the Retina

Robert L. Linsenmeier, PhD
Northwestern University, Evanston, IL


11 AM – 11:50 AM – Friday, March 20, 2015
McNair Hall Auditorium – College of Engineering


Like all neural tissue, the retina is dependent on a continuous supply of oxygen.  The retina obtains oxygen from two circulations with very different properties, and interruption of either one can cause blindness.  The speaker will discuss the roles of these two circulations in supplying the retina, how retinal oxygenation changes in several disease states (retinal detachment, retinal artery occlusion, and macular degeneration), and how oxygenation could be restored.  This work provides a good example of the interplay between mathematical modeling of oxygen diffusion and consumption and microelectrode measurements of oxygen tension in the mammalian retina.


About the Speaker:

Dr. Robert Linsenmeier has joint appointment at Northwestern University in Biomedical Engineering in the Robert R. McCormick School of Engineering and Applied Science, and in Neurobiology and Physiology in the Weinberg College of Arts and Sciences, with an additional appointment in Ophthalmology. His primary teaching is in human and animal physiology. He is the Director of the Northwestern Center for Engineering Education Research. Prior positions he has held include Associate Director of the Interdepartmental Neuroscience Graduate Program, Associate Director of the VaNTH Engineering Research Center in Bioengineering Educational Technologies, and Chair of the Northwestern’s Biomedical Engineering Department. He is a Fellow of the American Institute of Medical and Biological Engineering (AIMBE), the Biomedical Engineering Society, and the Association for Research in Vision and Ophthalmology. He chaired the Annual Meeting of the Biomedical Engineering Society in 2006, the Third Biomedical Engineering Education Summit in 2008, and the Annual Event of AIMBE in 2011. His research interests are in the role of retinal oxygen transport and metabolism in both normal physiological conditions and disease, and in bioengineering and physiology education.
