Deep-learning based, automated segmentation of macular edema in optical coherence tomography

In this study, the authors developed a convolutional neural network that successfully detected intraretinal fluid on ocular coherence tomography images. Macular edema, characterized by loss of the blood retinal barrier in very small retinal blood vessels, leads to the accumulation of fluid in the retina that can interfere with vision. The degree of macula edema present is usually inferred by measuring central retinal thickness on ocular coherence tomography images, but this measurement does not fully capture the extent and severity of the intraretinal fluid present.

Deep learning is effective for the classification of OCT images of normal versus Age-related Macular Degeneration

Optical coherence tomography (OCT) is the most commonly obtained imaging modality in ophthalmology and represents a dense and rich imaging dataset when combined with labels derived from the electronic medical record. In this study, the authors developed a novel deep learning approach to distinguish normal OCT images from images from patients with age-related macular degeneration.
