Macular Degeneration clinical trials at UC Davis
3 research studies open to eligible people

  • A Study of Age-Related Macular Degeneration (vision loss) and Reticular Pseudodrusen (yellow pattern in the vision part of eye)

    open to eligible people ages 55 years and up

    Objective: To learn more about AMD. Eligibility: People ages 55 and older with any of the following: AMD or changes in the retina that put them at risk for AMD RPD Healthy eyes Design: Participants will be screened with: Eye exam: The pupil will be dilated with eye drops. Eye pressure and movements will be checked. Pictures will be taken of the inside of the eye. Reading an eye chart. Optical coherence tomography (OCT): The eyes are dilated. A machine measures the thickness of the retina. Participants will have a first visit that includes: Repeat of screening procedures Medical history Physical exam Questions about vision and general health Dark adapted fundus perimetry: Participants sit in the dark for 40 minutes. Then they sit at a machine that shines lights in the eyes. Dark adaption testing: Participants sit in the dark for 45 minutes. The pupils are dilated. They push a button when they see light in a machine for up to 1 hour. Participants will have annual visits for up to 5 years to repeat the tests in the first visit. Participant data may be shared for other research. ...

  • Metformin vs. no treatment in the progression of geographic atrophy (GA), a type of age-related macular eye degeneration (AMD)

    “Can Metformin, used to treat Diabetes, slow the progression of geographic atrophy in patients with age-related macular eye degeneration?”

    open to eligible people ages 55 years and up

    The purpose of this study is to determine whether metformin, an FDA-approved drug for the treatment of type II diabetes, is a safe and effective treatment to decrease the progression of geographic atrophy in non-diabetic patients with Age-related Macular Degeneration (AMD).
