London- High School students have invented a device that can detect signs of degenerative eye disease, especially for patients with diabetes.

The Eyeagnosis system uses a 3D-printed lens and an AI-enabled smartphone app to diagnose diabetic retinopathy.

Kavya Kopparapu and her team—including her brother, Neeyanth, and her high school classmate Justin Zhang developed this system because her grandfather, who lives in a small city on India’s eastern coast, began exhibiting symptoms of diabetic retinopathy in his eye.

The system is expensive and according to “TechCrunch” the “A 3-D-printed mount and lens lets retinal scans be taken with the phone, and a machine learning system using readily available services and trained on thousands of such images does the diagnosis.”

The work was presented at an O’Reilly Artificial Intelligence Conference, and was considered by experts as the first of its kind to be fully equipped and cheap.

Some scientists believe that of 415 million diabetics worldwide, one-third will develop retinopathy, while fifty percent will be undiagnosed.
