Project duration

The project duration was from 10/2012 to 9/2013.

Short description

The project addresses a wide-spread medical condition called diabetic retinopathy. The cause of diabetic retinopathy is damage to blood vessels of the retina. Diabetic retinopathy is the leading cause of blindness. Diabetic patients with type 1 and type 2 diabetes have a greater risk for this condition. Suffering from severe diabetes for a longer period of time increases the chance of getting retinopathy. 

The goal of the project is to develop image processing and analysis methodology for computer-based interpretation of images obtained by retinal photography.  The goal of quantitative image analysis is to detect if a patient retina photograph shows a normal retina or a retina affected by diabetic retinopathy. This goal will be achieved by recognizing the relevant structures on the retina including blood vessel tree, fovea, and blind spot. In the second phase of the project, the goal is to quantify the progress of the disease.
