MELBOURNE, Australia, April 20, 2017 /PRNewswire/ -- IBM (NYSE: IBM) this week released the results of new research using deep learning and visual analytics technology to advance early detection of diabetic retinopathy (DR)1. The results, which classify the degree of severity of the disease in an eye image, exceed other currently published research efforts for severity classification using deep learning and pathology insights.
The research found that a new method created by the IBM team achieved an accuracy score of 86 percent in classifying the severity of the disease across the five levels recognized on the international clinical DR scale (no DR; mild; moderate; severe; proliferative DR). By being able to quickly and accurately identify both the presence and severity of diabetic eye disease, this research could potentially help doctors and clinicians have a better view of disease progression and determine treatment.
Diabetic retinopathy is one of the world's leading causes of blindness and affects one in three of the 422 million people who suffer from diabetes globally2. If left untreated, diabetic eye disease can lead to permanent blindness, however early detection and treatment can reduce the risk of blindness by 95 percent2.
Based on more than 35,000 eye images accessed via EyePACS, the IBM technology was trained to identify lesions such as micro-aneurysms, haemorrhages and exudates to indicate damage of the retina's blood vessels and assess both the presence and severity of the disease. The novel method for classifying the severity level of DR combines deep learning techniques, convolutional neural networks (CNN), with a dictionary-based learning to incorporate DR specific pathologies. Over time, IBM Research scientists will continue to advance the system to increase its understanding of diabetic retinopathy and the pathologies manifested in the retina from the disease.
"The alarming projections of the number of patients with diabetic retinopathy have major implications for the health system. The loss of vision from the condition can impose an enormous burden on the individual, including a loss of capacity to work and the need for intensive community support," said Dr. Peter van Wijngaarden, Principal Investigator at Centre for Eye Research Australia, Department of Ophthalmology, University of Melbourne. "To substantially reduce the number of people unnecessarily losing vision from diabetic eye disease, there is a real need for innovation to improve effective screening of those who are at risk to enable early sight-saving treatment."
