Towards a better understanding of glaucoma through fundus photography

Glaucoma is one of the leading causes of preventable blindness. Known as “the silent thief of sight”, it is asymptomatic until it produces a permanent and irreversible damage of the retinal nerve fiber layer. A gold standard imaging technique to identify the disease is still missing: currently, glaucoma is diagnosed using multiple studies, including microperimetry, optical coherence tomography and color fundus phography. As a consequence, detecting it at an early stage through screening campaigns is still prohibitive.

In this project we aim to improve the usage of color fundus photography in the context of glaucoma screening. To this end, our purpose is to introduce novel deep learning based approaches to discover novel biomarkers on these images. By means of our techniques, clinicians will be able to diagnose glaucoma with higher sensitivity and specificity using this low-cost imaging technique.
