  • Comparing Preoperative Injection of Mitomycin-C vs. Intraoperative Injection of Mitomycin-C vs. Topical Application of Mitomycin-C (Conventional Use) in Trabeculectomy

    open to eligible people ages 20-85

    In this Pilot explorative study, the investigators are going to estimate and compare the outcomes of three different delivery methods of MMC for Trabeculectomy: a subconjunctival injection of MMC 0.002% at the site of future Trabeculectomy two to four weeks before the surgery, a subconjunctival injection of MMC 0.01% intraoperatively and topical sponge applied MMC 0.02% intraoperatively (typical use) in patients with Primary Open Angle Glaucoma who did not have any filtering surgeries before. After obtaining informed consent from the patients, the patients are randomly divided into three groups via a block randomization method: Group A receives 0.1 mL MMC 0.002 % (0.1mL MMC 0.02mg/mL) subconjunctival injection preoperatively in superior conjunctiva at the site of future Trabeculectomy surgery. Group B receives 0.1mL MMC 0.01% subconjunctival injection intraoperatively at the site of Trabeculectomy and Group C receives conventional sponge delivery of MMC 0.02% intraoperatively. To avoid observer bias during postoperative evaluation of results, IOP staff obtaining measurements of IOP will be masked to the randomization allocation. All groups undergo conventional Trabeculectomy surgery (fornix-based) as scheduled, and the same routine follow up and post-op regimen will be scheduled for all three groups. Patients are routinely visited in the clinic at first day postoperatively, one week (+/-2 days), one month (+/-1 week), three months (+/-2 weeks), six months (+/-3 weeks) and finally at one year (+/-(4 weeks)). In each of these visits we will be assessing: Visual acuity, intraocular pressure, number and type of glaucoma medication, slit lamp examination of the anterior segment and fundus examination.

  • Diagnostic Innovations in Glaucoma Study

    open to eligible people ages 18 years and up

    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.

  • Advanced Glaucoma Progression Study

    Sorry, in progress, not accepting new patients

    Glaucoma is one of the leading causes of blindness in the world. The key to prevention of visual loss from glaucoma is early detection of the disease or its progression and timely treatment. The proposed study will investigate the role of various tests in improving detection of disease progression in advanced glaucoma. Evaluation of the peripheral field of vision (visual field examination) remains the current standard for detection of progression in glaucoma. However, there is a lot of variability or inconsistency in eyes with advanced glaucoma, which could make it difficult to detect worsening of glaucoma with visual fields. The optic nerve demonstrates significant damage in such eyes and hence oftentimes repeat imaging of the optic nerve head is not helpful for detection of change. Therefore, imaging of the central retina (the innermost sensitive tissue lining the inside of the eye), called macula, has been proposed to supplant imaging of the nerve in eyes with severe glaucoma. The macula aids in detailed central vision. Since the macular retinal neural cells are the last ones to be affected in glaucoma, measurement of macular retinal thickness could provide significant information with regard to the course of glaucoma. In the proposed study, glaucoma patients will be tested and followed with various measurements done with newer versions of optical coherence tomography (OCT) imaging and visual field machines. The patients will undergo repeat imaging and visual field testing every 6 months over the course of 5 years. Rates of change will be estimated. We will explore if changes in various outcome measures derived from imaging are correlated with the corresponding visual field changes in glaucoma, and whether the former can be used as an alternative method for detecting simultaneous or subsequent glaucoma progression. The hypothesis for this proposed research is that macular OCT parameters are valid structural measures that can be used especially in advanced disease to follow the course of glaucoma.

  • Advancing Understanding of Transportation Options

    Sorry, in progress, not accepting new patients

    This Stage II randomized, controlled, longitudinal trial seeks to assess the acceptability, feasibility, and effects of a driving decision aid use among geriatric patients and providers. This multi-site trial will (1) test the driving decision aid (DDA) in improving decision making and quality (knowledge, decision conflict, values concordance and behavior intent); and (2) determine its effects on specific subpopulations of older drivers (stratified for cognitive function, decisional capacity, and attitudinally readiness for a mobility transition). The overarching hypotheses are that the DDA will help older adults make high-quality decisions, which will mitigate the negative psychosocial impacts of driving reduction, and that optimal DDA use will target certain populations and settings.

  • African Descent and Glaucoma Evaluation Study

    Sorry, accepting new patients by invitation only

    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.

  • Effects of a Single Osteopathic Manipulative Treatment (OMT) on Intraocular Pressure (IOP) Reduction

    Sorry, accepting new patients by invitation only

    Glaucoma is a group of eye diseases, which in most cases produce increased pressure within the eye (intraocular pressure or IOP). Over time, the elevated IOP causes damage to the optic nerve, which can then lead to visual loss and if unchecked, to complete blindness over the course of years. OMT has been shown to affect cranial structure physiology including the possibility of lowering IOP by improving the drainage of intraocular fluid. This randomized study is designed to obtain data to evaluate the effect of OMT on IOP lowering and, if supportive, provide preliminary data for larger clinical trials.

  • Multicenter Study Assessing the Efficacy and Safety of DE-126 Ophthalmic Solution 0.002% Compared With Timolol Maleate Ophthalmic Solution 0.5% in Subjects With Primary Open Angle Glaucoma or Ocular Hypertension

    Sorry, not currently recruiting here

    Reduction of elevated pressure in the eye (Intraocular pressure, or 'IOP') with eye drop medications has been shown to be effective in delaying or preventing the progression of glaucoma, and it is the only proven method for reducing the risk of glaucomatous visual field loss. This study is being conducted to determine how well DE-126 ophthalmic solution works (efficacy) in safely lowering IOP when dosed as topical eyedrops. This study will evaluate the safety and efficacy of DE-126, ophthalmic solution in subjects with Primary Open Angle Glaucoma (POAG) or Ocular Hypertension (OHT). The IOP will be measured at 3 different times throughout the day, over 4 total visits during a 3-month treatment period (with up to 4 extra weeks observation if the patient must stop taking current eye drops to lower IOP). Safety assessments will be done throughout the study, including ocular signs and symptoms, and vital signs. While the most important time-point to measure IOP in this study and evaluate efficacy will be at the final study visit (month 3), IOP values will also be evaluated at other visits throughout the 3-month treatment period.
