Researchers at the National University of Singapore are aiming to apply deep learning to optical coherence tomography (OCT) images in order to modernise the diagnosis of glaucoma and obtain a better understanding of how the disease progresses over time.

At the annual meeting of the Association for Research in Ophthalmology and Vision in Vancouver, Canada, Alexandre Thiery, PhD, discussed the work being done by the Optical Coherence Tomography & Artificial Intelligence for Glaucomatous Optic Neuropathy (OCTAGON) team.

Dr Thiery, co-principal investigator of OCTAGON, explained that the group is focusing on the optic nerve head because it represents the main site of glaucoma damage.

“Glaucoma is a complex disease in which there are 3-dimensional structural changes, and our approach is to exploit deep-learning to provide 3-dimensional segmentation of the optic nerve head,” Dr Thiery said.

“The main advantage that we see for our approach is that we are able to extract parameters that are highly correlated with glaucoma but that are impossible to obtain with conventional methods.”
