Ophthalmic Vascular Research Program

History

With support from the Kruse Endowment Fund and the establishment of the Kruse Centennial Chair in Ophthalmology of Baylor Scott & White Health (BSWH), Dr. Lih Kuo – Regents Professor of Medical Physiology at the Texas A&M Health Science Center with a specialization in microvascular research – was recruited as the Endowed Chair and the Director of the Ophthalmic Vascular Research Program (OVRP) in 2003 through a national search.

The OVRP is the first in the nation and the world to be designated for ophthalmic vascular research in translational medicine. Dr. Robert Rosa (clinician scientist in ophthalmology) and Dr. Travis Hein (basic scientist in microcirculation) joined the OVRP as core members of the team to facilitate retinal disease research. Dr. Kuo moved his laboratories from College Station to the Temple campus in March 2004.

The OVRP has grown significantly in the past 18 years and has received national/international recognition in ophthalmic vascular research and benefited the institution in translational research and education. In 2019, the BSWH eliminated all fundamental research programs on the Temple campus, and the OVRP was then adopted by the Department of Medical Physiology at the Texas A&M University Health Science Center. In 2020, the OVRP moved back to the Texas A&M Medical Campus in Bryan, TX, to continue the mission.

 

Goals & Accomplishments

Goals: The long-term goal of the OVRP is to establish a nationally and internationally recognized ophthalmic research center or Institute at the Texas A&M University Health Science Center for translational and clinical research to ultimately benefit patient care and improve quality of life. The short-term (5 years) goals are to 1) develop retinal disease animal models resembling human pathophysiology; 2) conduct translational research on diabetic retinopathy, hypertensive retinopathy, retinal degeneration, and spaceflight-associated neuro-ocular syndrome; and 3) develop therapies for vision-threatening eye diseases such as diabetic retinopathy, retinitis pigmentosa, and macular degeneration.  

Achievements: The scientific quality and merit of the OVRP can be evaluated in five categories: publications, research funding, scientific review, international visiting scholars, and industry consulting. The OVRP investigators have published more than 60 peer-reviewed premier publications, 65 abstracts, and 17 book chapters. The OVRP has been successful in securing grants and funding from multiple foundations, philanthropic donations, as well as the NIH National Eye Institute and NASA. The OVRP has also obtained research funding from the Retina Research Foundation for the past 17 consecutive years with several research awards, signifying the scientific quality and merit of the OVRP. In total, the OVRP lab and clinical trials have been granted over 18 million dollars throughout the past decade. The investigators of the OVRP frequently receive invitations to review manuscripts and grants from various scientific journals and granting agencies, demonstrating the OVRP as a leading research program. The OVRP has hosted research sabbaticals for scientists from the US and foreign countries and provided research consulting to the pharmaceutical industry for drug development. These activities demonstrate the national/international leadership of the OVRP in retinal research.

 

Impacts on the Community/Patients

The OVRP is committed to promoting and advancing medical knowledge in the vision research community and to improving patient care and human health through the education and training of tomorrow’s health leaders. The OVRP Principal Investigators have trained and mentored more than 5 research associates, 3 postdoctoral researchers, 1 research scientist, 2 PhD students, and 2 MD/PhD students. Since 2003, there have been more than 30 MD and PhD trainees under OVRP supervision.

The OVRP has been instrumental in research education for many ophthalmology residents at BSWH and medical students at the Texas A&M University Health Science Center. Many OVRP former trainees are now directly involved in patient care as clinicians and clinician scientists at other institutions. The key members of the OVRP frequently present and disseminate medical knowledge in vision health and research and promote vision care locally, nationally, and internationally.
