Philadelphia Telemedicine Glaucoma Detection and Follow-Up Study

The project will be divided into following parts: * Phase 1 will consist of recruiting patients from primary care offices and federally qualified health centers across Philadelphia and Chester counties. Using fundus photography of optic nerve and macula via telemedicine and measurement of intraocular pressure, eye disease will be detected at Visit 1, followed by a comprehensive eye exam by a glaucoma specialist in the primary care setting to confirm the diagnosis (Visit 2) of qualifying participants requiring further evaluation. Predictive accuracy of optic nerve images to detect glaucoma, glaucoma suspect and other eye diseases as confirmed by the comprehensive eye exam will be evaluated. * Phase 2 will involve consenting, enrolling, and randomizing the qualifying participants confirmed by diagnosis at Visit 2 to either the Usual Care group or the Enhanced Intervention group and scheduling follow-up eye exams with a local, general ophthalmologist in an office-based setting (Visit 3). Enhanced intervention will use patient navigators and a social worker to reduce barriers to follow-up eye care. * Phase 3 will involve monitoring the randomized participants attendance of proximal (1-2 months) and distal (3 years) follow-up care appointments (Visits 3-8) with a local ophthalmologist. Adherence to recommendations for follow-up eye care will be the primary outcome measure. A comprehensive estimation of intervention costs and cost-effectiveness of detecting eye diseases and vision impairment in a high-risk population will also be conducted. Protocols, materials, and results will be disseminated to other organizations, stakeholders and communities in order to expand detection of glaucoma, other eye diseases, and visual impairment, and to further refine these approaches.
