Glaucoma screening to improve health of at-risk Californians
Official title: Novel Telehealth Technologies to Detect and Manage Glaucoma and Vision-threatening Eye Diseases in High-risk Populations
Run by University of California, San Francisco · NCT06854198 · Data updated 2026-11-12
This project will try mobile telemedicine glaucoma screening using OCT, fundus photos, and tonometry for older Black and Hispanic adults and people with diabetes seen at community clinics to see if it finds more undiagnosed glaucoma than giving education or delaying screening.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are patients seen at participating FQHCs who are Black and at least 50 years old, Hispanic and at least 65 years old, or have diabetes and are at least 50 years old.
✕Probably not a fit
Patients who recently had an eye exam within the past year, lack a valid phone number or mailing address, live outside the participating clinics' service area, or already have a known glaucoma diagnosis may not get added benefit from this screening.

What this trial studies
This is a randomized trial comparing a mobile, telemedicine-based glaucoma screening program (optical coherence tomography, color fundus photography, and tonometry) to an educational brochure or delayed intervention. Participants are drawn from Federally Qualified Health Centers in the San Francisco Bay Area and must meet age and risk-based inclusion criteria. The primary outcome is the number of new glaucoma diagnoses detected; secondary outcomes include rates of cataract surgery, distance vision correction, and vision-related quality of life at one year. Screening images and measurements are reviewed remotely by clinicians to guide referral and follow-up.
Why it matters
Potential benefit: If successful, the program could find glaucoma earlier in underserved patients and increase timely treatment to help prevent vision loss.
How similar studies have gone: Prior telemedicine and community-based glaucoma screening efforts using portable imaging and intraocular pressure have shown promise in increasing detection, but results and implementation have been variable across settings.
