Early Retinopathy Detection Helps Prevent Blindness in Wisconsin
Innovative screening programs are reducing the leading cause of blindness in Wisconsin working-age adults, thanks to efforts led by researchers at the University of Wisconsin School of Medicine and Public Health.
The initiative focuses on early detection of diabetic retinopathy, a complication of diabetes that damages the small blood vessels in the retina, potentially leading to retinal detachment and blindness. Diabetic retinopathy remains the leading cause of blindness among working-age adults in Wisconsin, affecting thousands of residents.
A Personal Story Highlights the Need for Screening
Jeri Shultis, a Wisconsin resident, experienced blurry vision during a family event, which led to a diagnosis of diabetes—a condition he was unaware he had. Since his diagnosis in 2016, he has managed his diabetes with treatment at Mile Bluff Medical Center. Regular eye screenings are a vital part of his care plan, exemplifying the importance of early detection.
“My eyes were just so blurry all day,” Shultis recalled. “I made an appointment and found out I had diabetes. Early screening can save sight.”
Innovative Programs Combat Barriers to Eye Care
Researchers like Dr. Yao Liu have developed teleophthalmology programs that enable primary care clinics to use retinal cameras during routine diabetes checkups. The images are sent to specialists for review, facilitating timely follow-up and treatment for patients at risk.
Since the program’s inception, over 2,000 patients have received vision-saving interventions, with screening rates rising to top national levels. Dr. Liu emphasizes the program’s positive reception: “Getting screened during a primary care visit is convenient and encourages more patients to participate.”
Expanding Impact Through Research and Innovation
Supported by the National Eye Institute, Liu’s team is testing the program’s effectiveness across additional clinics nationwide, including in Wisconsin, Alabama, California, and more. The ultimate goal is to make teleophthalmology a standard part of primary care across the country and reduce the incidence of diabetes-related blindness.
The Role of Technology and Artificial Intelligence
New advances such as AI-based screening technologies are being developed to provide instant results, especially for patients in remote or underserved areas. Dr. Roomasa Channa explains that AI can recognize signs of diabetic retinopathy and facilitate immediate referrals, potentially improving follow-up care.
However, challenges remain, including uncertainties about funding and policy changes affecting ongoing research projects.
Addressing Root Causes and Public Awareness
Experts argue that the key to reducing blindness due to diabetic retinopathy is widespread screening and early intervention. Education campaigns and accessible technology can significantly lower the risk, but public awareness remains crucial.
The ongoing efforts in Wisconsin exemplify how innovative healthcare strategies can save sight and improve lives, emphasizing that early detection and proper management are vital in combating preventable blindness.
