Filter by:The present study is designed to compare the response of choroidal blood flow to the hand-grip test in glaucoma patients with and without visual field progression.
Based on these recent observations and findings in this new animal model of pigmentary glaucoma in the DBA/2J mouse, we propose that immune system abnormalities in the anterior chamber may play a possible role in the development of pigmentary glaucoma and possibly primary open-angle glaucoma (POAG) in humans.
According to the National Eye Institute, Glaucoma affects about three million Americans. Among Blacks in the United States, open- angle glaucoma is the leading cause of irreversible visual loss. Glaucoma is four times more likely to develop in Blacks than in Whites. This is a prospective longitudinal, multi- site observational cohort study designed to obtain visual function and optic nerve structure data on eyes of Black and White Americans. The investigators will evaluate the relationship between changes in the structure of the eye and the vision loss caused by glaucoma.This is the first study where both populations are matched for quality of care and equal access to care.
The overarching goal of our research study is to evaluate changes in visual function and optic nerve topography (the structure of the back of the eye) in patients with glaucoma (increased susceptibility to pressure inside the eye that can cause loss of vision) or those with an increased risk of developing the disease. The purpose of this study is to determine the best methods for detecting the presence or progression (worsening over time) of glaucoma in patients with and without myopia and its effects on daily and visual function and quality of life. With several sources of NIH and foundation funding over the last twenty years we have designed a robust research protocol to address the most challenging aspects of glaucoma management. The most recent focus of this research is 1) to improve our ability to detect open angle glaucoma in individuals with myopia and in individuals of European and African descent, 2) to determine whether monitoring of the retinal vasculature with new optical imaging instruments can improve glaucoma management and elucidate the pathophysiology of the disease, and 3) to differentiate between age-related changes and glaucomatous progression. The grants supporting this project include 3 NIH funded studies, 1) the University of California, San Diego UCSD -based "Diagnostic Innovations in Glaucoma Study" (DIGS funded since 1995): 2) the "African Descent and Glaucoma Evaluation Study" (ADAGES funded since 2002), 3) the Brightfocus Foundation National Glaucoma Research Program and 4) the UCSD-based "Diagnosis and Monitoring of Glaucoma with Optical Coherence Tomography Angiography" (funded since 2018). The ADAGES is a multi-center study with data collection also conducted at 2 other academic sites, the University of Alabama at Birmingham, and Columbia University. Enrolled healthy participants, glaucoma suspects and glaucoma patients are generally asked to return for two or more visits a year for several years. We then analyze whether the glaucoma patients are progressing and what factors influence their glaucoma status compared to healthy subjects and individuals suspected of having glaucoma.
