  • Abstract: The analysis of retinal Spectral Domain Optical Coherence Tomography (SD- OCT) images by trained medical professionals can be used to provide useful in- sights into many various diseases. It is the most popular method of retinal imaging due to it’s non invasive nature and the useful information it provides for making an accurate diagnosis. In this paper, we present a deep learning approach for the au- tomating the segmentation of cystic macular edema (fluid) in retinal OCT B-Scan images. Our network makes use of atrous convolutions, skip connections, weight decay and significant image augmentation to ensure the most accurate segmenta- tion result possible without the need for any features to be manually constructed. The network is evaluated against a publicly available dataset and achieved a max- imal Dice coefficient of 95.2%, thus making it the current best performer on that dataset.
