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.

Conditions

Interventions

OTHER

Glaucoma screening with optical coherence tomography (OCT), color fundus photography, and tonometry

Participants will be called and offered a screening appointment. At the appointment, visual acuity, OCT, color fundus photography, tonometry, and visual field testing will be performed. The images will be assessed for abnormalities. Participants meeting referral criteria will be referred for a comprehensive eye examination with an eye care provider.

OTHER

Educational Brochure

A brochure about glaucoma screening will be mailed to participants. The brochure will include contact information of a staff member who can schedule an appointment for a comprehensive eye examination.
