I received my undergraduate degree from the Birla Institute of Technology and Science, Pilani, India in 1992 majoring in Electronics Engineering. I then moved to the United States for graduate studies and completed a M.S and Ph.D. degree in 1998 in Biomedical Engineering from Case Western Reserve University, Cleveland, Ohio. My work, carried out under the mentorship of Dr. John Leigh, primarily examined the interactions between visual-oculomotor and vestibular systems. I did post-doctoral work at the Yerkes National Primate Research Center, Emory University with Dr. Michael Mustari from 1999 to 2002. During this time I learnt the technique of single cell extracellular recording in the awake-behaving monkey and also became interested in examining visual-oculomotor mechanisms in the strabismic primate. I was appointed to the faculty at Emory University in 2002 and received an independent investigator award from the National Institutes of Health in 2004 to study neural circuits mediating binocular coordination of eye movements in the strabismic monkey. I have since maintained continued NIH funding. I joined the faculty of the College of Optometry, University of Houston in 2009. The goal of research in my laboratory is to continue to uncover the disruption of neural processing in various brain areas in the strabismic monkeys. A better understanding of neural mechanisms that are affected in the different forms of strabismus will help develop rationally based therapy.
The focus of research in my laboratory is to investigate disruption of eye movement control in animal models for strabismus (ocular misalignment). Strabismus is a common visual developmental disorder affecting 2?5% of all human infants. Though the exact etiology of strabismus is still unknown, it is clear that disruption of binocular visual information in infancy plays a critical role in development of strabismus. Many seminal behavioral, anatomical and physiological studies have revealed various aspects of visual sensory deficits that are associated with the strabismic condition. By the same token, we know relatively little about disruptions in neural oculomotor (eye movement) circuits, though these structures must also be involved in maintaining the steady-state strabismus. The possible involvement of such structures ranges from altered eye muscle lengths to neural mechanisms that alter eye muscle tone or contractility. Our research is therefore directed towards identifying and understanding the roles of specific areas in the brain that may be involved in producing oculomotor properties describing the strabismus state. Our strategy is to utilize a basic science approach with studies in animal models, incorporating concepts, tools and techniques developed via basic science studies of the oculomotor system. To this end, we use a multi-pronged strategy involving behavioral studies of eye alignment, eye movements and ocular accommodation, MRI studies evaluating extraocular muscle (EOM) structure and single cell recording studies of information processing in neural oculomotor circuits.
David A. Berntsen, OD, PhD, FAAO completed his Doctor of Optometry degree in 2002 at the University of Houston College of Optometry in Houston, TX. He then completed a Cornea and Contact Lens Advanced Practice Fellowship at The Ohio State University College of Optometry in Columbus, OH. The fellowship program combined a two-year residency with a Master of Science degree in Vision Science, which Dr. Berntsen completed in 2004. He then completed a PhD in Vision Science at Ohio State in 2009.
Dr. Berntsen's research interests include myopia, contact lenses, and aberrations of the eye. He conducted the Study of Theories about Myopia Progression (STAMP), a two-year clinical trial evaluating theories of juvenile-onset myopia progression. He has conducted adult and pediatric studies involving contact lenses and higher-order aberrations of the eye. Dr. Berntsen is the Principal Investigator of the University of Houston clinical site for the Bifocal Lenses In Nearsighted Kids (BLINK) Study, a multicenter randomized clinical trial sponsored by the National Eye Institute. The BLINK Study is a collaborative effort between the University of Houston and The Ohio State University that will determine whether commercially available soft bifocal contact lenses slow the progression of nearsightedness in children.
