Alabama Screening and Intervention for Glaucoma and Eye Health Through Telemedicine (AL-SIGHT): Study Design and Methodology.

PRCIS: This paper presents the methods and protocol of a community-based telemedicine program to identify glaucoma and other eye diseases.

PURPOSE: To describe the study rationale and design of the Alabama Screening and Intervention for Glaucoma and eye Health through Telemedicine project.

METHODS

The study will implement and evaluate a telemedicine-based detection strategy for glaucoma, diabetic retinopathy, and other eye diseases in at-risk patients seen at federally qualified health centers located in rural Alabama. The study will compare the effectiveness of the remote use of structural and functional ocular imaging devices to an in-person examination. Study participants will receive a remote ocular assessment consisting of visual acuity, intraocular pressure, visual field testing, and imaging of the retina and optic nerve with spectral-domain optical coherence tomography, and the data will be reviewed by an ophthalmologist and optometrist. It will also compare the effectiveness of financial incentives along with a validated patient education program versus a validated patient education program alone in improving follow-up adherence. Finally, cost and cost-effectiveness analyses will be performed on the telemedicine program compared with standard in-person care using effectiveness measured in numbers of detected eye disease cases.

CONCLUSIONS

The study aims to develop a model eye health system using telemedicine to prevent vision loss and address eye health among underserved and at-risk populations.
