Synopsis: Electronic eye exams could become popular in the U.S. among patients who see them as an easy way to visit the eye doctor.

Why it matters: This report discusses the potential of telemedicine to enhance access to eye examinations for individuals with diabetes, aiming to prevent diabetic retinopathy-a leading cause of blindness. The study highlights that electronic eye exams, involving retinal photographs taken at primary care offices and reviewed remotely by eye specialists, could increase screening rates among diabetic patients. Notably, in England and Wales, the implementation of a nationwide telemedicine screening program has led to a decline in diabetic retinopathy as the primary cause of blindness. The report also reveals that while only 3% of surveyed patients were initially aware of telemedicine, 69% considered it more convenient than traditional eye exams once informed. This suggests that telemedicine could address barriers such as high costs, limited access, and transportation difficulties, thereby improving eye care for underserved populations - Disabled World (DW).

Introduction

Telemedicine could improve eye exam access for people with diabetes - Virtual collaboration may one day help prevent the top cause of blindness.

Main Item

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.

Early detection and treatment is key to prevent blindness from diabetic retinopathy, but fewer than 65 percent of U.S. adults with diabetes undergo screening.

In underserved populations, rates can drop as low as 10 or 20 percent.

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.

How Electronic Eye Exams Work

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 percent of the 97 patients surveyed had heard of telemedicine. But once telemedicine was explained, 69 percent 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."

About the Study

Study patients were recruited from the Duke University Medical Center and the Durham Veterans Affairs primary care and endocrine clinics. The National Eye Institute, Research to Prevent Blindness and the National Center for Advancing Translational Sciences funded the study.

U-M co-authors include Paul P. Lee, M.D., J.D., chair of the Department of Ophthalmology and Visual Sciences; Paula Anne Newman-Casey, M.D.; Sean O. Hansen, M.D., Sophia Y. Wang, M.D., and Nita G. Valikodath. The team collaborated with the University of Washington's Thellea Leveque, M.D., MPH.
