About this study

In plain language

This study tests whether eye screening finds more cases of glaucoma than education alone or screening later. Glaucoma is an eye disease that gets worse over time and may have no symptoms at first. The study is for older Black or Hispanic people, or people with diabetes, who recently visited a qualifying health center.

The vast majority of glaucoma cases in the United States go undetected and untreated until the late stages of the disease. Open-angle glaucoma is a progressive condition that is asymptomatic in its early to moderate stages and may be amenable to screening through telemedicine-based approaches. This study is a randomized trial to evaluate whether glaucoma screening with established tests (e.g., optical coherence tomography, fundus photography, and tonometry) is more effective for detecting undiagnosed glaucoma cases compared to education alone or delayed intervention.

Compensation is read from the study's own description and may be missing — always confirm with the study team.
