Dr. Ostrin is a fellow of the American Academy of Optometry and a recipient of the American Optometric Foundation Ezell Fellowship.
My research interests include environmental and behavioral influences on circadian rhythm and eye growth. Light exposure has a close link with numerous aspects of human physiology and has been implicated in several different pathological processes including myopia development, circadian rhythm disturbances, mood disorders, cancer, and metabolic disorders. The intrinsically photosensitive retinal ganglion cells (ipRGCs) are an inner retinal photoreceptor type that respond directly to short wavelength blue light, and are responsible for non-image forming functions including circadian rhythm entrainment and pupil size. Ongoing projects in the lab include 1) measuring and correlating light exposure with ipRGC activity, circadian rhythm patterns, melatonin levels and refractive error, 2) determining the effects of blue light emitting devices (computers and hand held electronic devices) on ipRGC function and sleep/wake patterns, and 3) developing devices to continuously and objectively measure behaviors related to eye growth.

I was born and raised in Ann Arbor Michigan. After graduation from high school I attended the University of Michigan majoring mechanical engineering. Three years of that convinced me that I needed to rethink my educational goals. After 3 years in the Army I returned to Michigan and enrolled at Michigan State University in Psychology where, in a period of 5 years, I obtained a B.S., M.A. and Ph.D. in experimental Psychology. After graduation I joined the faculty of the Massachusetts College of Optometry where I taught Vision Science and began my career in clinical electrophysiology. While on the faculty I entered the accelerated clinical program for students with a Ph.D. degree and was granted the OD Degree after 2 years of study. One year later I came to the University of Houston and joined the Optometry College faculty. Over the years my interests have shifted from vision science to retinal pathology. I am presently the director of the Ocular Diagnostic Service and teach retinal pathology in the third year of the professional program.
My Clinical interests center largely on the retina and the optic nerve. The University Eye Institute, Ocular Diagnostic Service is one of the finest equipped facilities of its type in the world. I routinely use the full range of the classical electrical physiological tests (VEP, ERG & EOG) along with visual field testing, ultrasound, and the major scanning laser devices to diagnosis retinal and or optic nerve disease.
