Measuring Human Vision: One Cell at a Time

Austin Roorda (University of California, Berkeley)
Abstract / Description: 

Adaptive optics enables imaging of the retina and testing of human vision on a cellular scale. In this talk, I will discuss the latest development in ophthalmic adaptive optics technology and show examples of how it is being used to measure structure and function of the human eye. I will also discuss where we can expect to see the technology being applied in the next ten years.


Austin Roorda received his Ph.D. in Vision Science & Physics from the University of Waterloo, Canada in 1996. Since that time, Dr. Roorda has been pioneering applications of adaptive optics and ophthalmoscopy, including mapping of the trichromatic cone mosaic while a postdoc at the University of Rochester, designing and building the first adaptive optics scanning laser ophthalmoscope at the University of Houston, tracking and targeting light delivery to individual cones in the human eye at UC Berkeley, and being part of the first team to use AO imaging to monitor efficacy of a treatment to slow retinal degeneration. Since January 2005, he's been at the UC Berkeley School of Optometry where he is a member of the Vision Science and Bioengineering graduate programs. He is a Fellow of the Optical Society of America and of the Association for Research in Vision and Ophthalmology. Notable awards are the Glenn A. Fry award from the American Academy of Optometry (2009) and a John S. Guggenheim Fellowship (2014). In 2015, Dr. Roorda led one of the teams that was awarded the first round of funding though the National Eye Institute's Audacious Goals Initiative aimed at 'Restoring vision through regeneration of the retina'. His team's project involves the development of a novel system to measure function of individual retinal neurons in human eyes using adaptive optics, eye tracking and phase-resolved OCT.
