Background

Diabetic retinopathy occurs when prolonged high blood sugar levels cause damage to the blood vessels in the retina, the light-sensitive tissue at the back of the eye. This condition is the most common cause of vision loss among the over 30 million Americans living with diabetes. Despite the critical need for early detection, about 50% of diabetic patients do not receive annual screenings for retinopathy, largely due to the lack of regular visits to eye care professionals.

Innovation

The newly approved device, IDx-DR, is a software program that employs a machine learning algorithm to analyze retinal images captured with a specialized camera, the Topcon NW400. The procedure involves a primary care doctor uploading the digital images of a patient’s retinas to a cloud server where the IDx-DR software is installed. If the images meet quality standards, the software generates one of two results:

1. “More than mild diabetic retinopathy detected: refer to an eye care professional.”
2. “Negative for more than mild diabetic retinopathy; rescreen in 12 months.”

Should the AI detect a positive result, the patient is advised to consult an eye care specialist for further evaluation and potential treatment. IDx-DR is revolutionary as it delivers a screening decision independently, without requiring a clinician to interpret the images or results, thus enabling use by primary care providers who may not specialize in eye care.

Clinical Validation

The FDA’s approval of IDx-DR followed a rigorous evaluation of data from a clinical study involving 900 diabetic patients across ten primary care sites. The study assessed the accuracy of IDx-DR in detecting more than mild diabetic retinopathy. Results demonstrated that the device correctly identified the condition 87.4% of the time and accurately ruled it out in 89.5% of cases.

This case study highlights the transformative potential of ML in healthcare, exemplified by IDx-DR’s ability to enhance early detection and management of diabetic retinopathy, ultimately contributing to better health outcomes for millions of individuals with diabetes.
