The Ostrin lab studies 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.

Bifocal Lenses in Nearsighted Kids (BLINK) Study & BLINK2 Study - University of Houston College of Optometry Website

Bifocal Lenses in Nearsighted Kids (BLINK) Study & BLINK2 Study: PURPOSE To determine if soft bifocal contact lenses (typically used to help people over 40 see).

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.

The Richdale Lab - University of Houston College of Optometry Website - opt.uh.edu

Our research primarily focuses in the areas of cornea, contact lenses and refractive error. We are currently recruiting reseach subjects.

The Richdale lab conducts sponsored and investigator-initiated research aimed to understand patient reported outcomes, safety of contact lens treatments for myopia management.

Dr. Manny's research interests include development of vision, anomalies of binocular vision, refractive error, and vision screening. Clinical interests include infant and preschool vision and children with special needs. In addition, Dr. Manny leads studies in association with the Pediatric Eye Disease Research Group, and is currently investigating the effectiveness of atropine in myopia control.

The Porter lab’s main goals are to learn more about the mechanisms responsible for the development and progression of retinal diseases (such as glaucoma and photoreceptor-based degenerations) and how the retina develops in the normal eye.
