CHCF Expands Project to Prevent Diabetes-Related Blindness Through Telemedicine

Project improves access for patients who face obstacles to care


An innovative project to prevent diabetes-related blindness has proven so successful in California’s Central Valley that it is being expanded across the state, with a goal of serving 100 clinics and 100,000 patients, according to the California HealthCare Foundation (CHCF), the project’s sponsor.

“Diabetes is a major health threat in the Central Valley,” said Veenu Aulakh, M.P.H., CHCF senior program officer. “In addition to some of the highest rates of diabetes in the state, the problem is compounded by high numbers of poor and uninsured patients, a shortage of health providers, and a rural setting that poses transportation obstacles to getting care.”

The Foundation’s Better Chronic Disease Care program area funded a pilot project that uses telemedicine software developed by the University of California Berkeley School of Optometry, expert consultation, digital retinal cameras, and screenings during regular office visits at 13 Central Valley safety-net and rural clinics.

Diabetic retinopathy, which includes hemorrhages and lesions in the eye, is the leading cause of blindness among working-age adults, with 24,000 diabetics becoming legally blind each year in the United States. But with regular screening to identify those most at risk, blindness can often be prevented. “Half of all patients with diabetes don’t get recommended yearly eye exams,” said Jorge Cuadros, O.D., Ph.D., clinical professor of optometry at UC Berkeley. “The statistic is even worse in poor and rural communities.”

Cuadros heads the project, which uses EyePACS, a license-free Web-based software program for capturing and delivering retinal images. The project provides special digital retinal cameras to be used during regular primary care visits at the clinics. The high-resolution retinal photos are transmitted to optometrists and ophthalmologists at UC Berkeley for interpretation, diagnosis, and possible referral to specialists for further treatment. In the two-year pilot period, more than 12,000 patients received screenings, half of whom were diagnosed with some level of retinopathy. Some 15% required referrals (of those, 10% were for sight-threatening retinopathy and 5% were for other eye conditions).

The project has improved access to care and expert consultation, according to Christine Noguera, deputy CEO of Golden Valley Health Centers, whose clinics in Merced and Stanislaus Counties participated in the pilot. In a recent chart audit of patients with diabetes who had received the digital retinal exam, “not a single one had ever had a documented eye exam before their diabetic retinopathy screening,” said Noguera. By folding this service into their primary care visit, “it is absolutely more convenient — there’s no need to go to an unfamiliar facility across town — and the cost to the patient is built into the standard office visit charge, thus eliminating cost as a barrier to care.”

Just as important, Noguera added, clinics are using the retinal images as powerful tools to engage patients in diabetes self-management. “We show patients their own photo, compared with a photo of a healthy eye,” said Noguera. “Diabetes is largely invisible, but this is something tangible that they can see.”

CHCF is funding a $1.8 million expansion of this project and recently selected a group of California safety-net and rural clinics as participants in the first wave of expansion (see list below).
