 Telemedicine Could Help Improve Eye Exam Access for People With Diabetes

Early detection and treatment is key to prevent blindness from diabetic retinopathy, but fewer than 65% of United States adults with diabetes undergo screening. In underserved populations, rates can drop as low as 10 or 20%. Electronic eye exams could become popular in the U.S. among patients who see them as an easy way to visit the eye doctor.

After a nationwide telemedicine diabetic screening program in England and Wales, for example, diabetic retinopathy is no longer the leading cause of blindness there.

Similar e-health programs could grow stateside, where diabetic retinopathy remains the main driver of new-onset blindness. But it hasn't been known if patients would participate.

Researchers at the University of Michigan's Kellogg Eye Center conducted a study of older adults to find out. If services are convenient, patients will use them, the investigation found.

"Telemedicine has been shown to be a safe method to provide monitoring for diabetic eye care. If physicians plan to change the way that people get care, we must create a service that is appealing and tailored to the patients," says senior study author Maria Woodward, M.D., assistant professor of ophthalmology at Kellogg Eye Center.

Shifting screening to a telemedicine program could ease the burden on patients who face high costs of care, lack of access to care or have difficulty with transportation or getting time away from work, researchers say.

Finding ways to address screening will become more important in coming decades, as the number of people with diabetes is projected to more than double to 366 million worldwide by 2030.

Telemedicine allows primary care doctors to play a critical role in preventing eye damage.

Retinal photographs are taken of both eyes at the doctor's office using a no-dilation retina camera. The images can be sent over a secure, cloud-based network to an eye care provider who sends a report back to the primary care physician. Based on the findings, the patient is either scheduled for more photographs in the clinic or referred to an ophthalmologist.

In the study, published in Telemedicine and e-Health, only 3% of the 97 patients surveyed had heard of telemedicine. But once telemedicine was explained, 69% believed telemedicine could be more convenient than traditional one-on-one exams with a specialist.

Patients were less interested in telemedicine if they had been living with diabetes for a number of years, or if they had a good relationship with their doctor. They were more willing to participate if they thought telemedicine would be more convenient than a routine eye exam or they had other health issues that made it harder for them to get to the doctor.

"Patients with long-standing disease are less likely to trust a new, less-personal delivery model. In our study, the highest impact on willingness was convenience of telemedicine," says Woodward, who is a member of the U-M Institute for Healthcare Policy and Innovation. "Our results indicate that willingness to participate in telemedicine for diabetic retinopathy screening reflects how patients perceived convenience, the patient-physician relationship and their own health."
