Feasibility of a Bi-national Consulate-based Teleophthalmology Screening and Referral Protocol for Diabetic Retinopathy among Mexican Migrants in the United States.

Aims: To evaluate a bi-national consulate-based teleophthalmology screening service for diabetic retinopathy (DR) among Mexican migrants in the U.S.
Methods: Adult visitors (n=508) at Mexican consulates in California with self-reported diabetes underwent questionnaires and fundus photography. Photographs were graded for DR by retina fellows in Mexico via teleophthalmology. Participants were contacted with results and provided referrals when necessary.
Results: Nearly all (97.6%) participants were aware that diabetes can cause vision loss. One-quarter (24.4%) had undergone an eye examination in the past year. Barriers to care were cost (53.9%) and insurance (45.6%). Most (85.4-91.1%) reported that Spanish-speaking providers and provision of screening in primary care would increase participation in screening. Any DR, vision-threatening DR, or proliferative DR were found in 30.2%, 9.9%, and 5.4% of participants, respectively. Nearly one-fifth (19.5%) received referrals.
Conclusions: Screening in Mexican consulates may improve DR detection and treatment among Mexican migrants in the U.S.
