Glaucoma Screening to Enhance At-Risk Californians' Health

Summary

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.

Detailed Description

Specific Aim 1: To determine the effectiveness of a telemedicine-based glaucoma screening program for detecting glaucoma. The investigators hypothesize that a mobile screening intervention incorporating optical coherence tomography (OCT), fundus photography, and tonometry will result in a greater number of new glaucoma diagnoses compared to education alone or delayed treatment. Specific Aim 2: To determine whether a telemedicine-based glaucoma screening program provides benefits beyond glaucoma detection. The investigators hypothesize that (A) individuals randomized to the screening intervention will have higher rates of cataract surgery and distance vision correction one year after screening, and (B) those in the screening intervention will report higher vision-related quality of life one year after screening.
