DRUSAS - Automatic Detection of Drusens in Fundus Images - Past Research Projects
Project Summary
Drusen is a retina abnormality considered a risk factor for age-related macular degeneration (ARMD) that is one of the leading causes of blindness. It is noticed in retina images as small sized yellow spots. To evaluate therapy effectiveness ophthalmologists usually do a visual inspection what is fastidious and not reproducible. Published data shows that the agreement between medical specialists in Drusen identification is only 67%.

The goal of this project is the development of a methodology for automatic unsupervised detection and modeling of Drusen spots using image processing techniques. The methodology will be validated with a software prototype that will certainly improve the detection and quantification of Drusen.

It is also a main objective for the project to do a clinical validation of it, to compare the results with the ones obtained by ophthalmologists.
