Abstract |
We address a novel problem domain in the analysis of optical coherence tomography (OCT) images: the
diagnosis of multiple macular pathologies in retinal OCT images. The goal is to identify the presence of
normal macula and each of three types of macular pathologies, namely, macular edema, macular hole,
and age-related macular degeneration, in the OCT slice centered at the fovea. We use a machine learning
approach based on global image descriptors formed from a multi-scale spatial pyramid. Our local features
are dimension-reduced local binary pattern histograms, which are capable of encoding texture and shape
information in retinal OCT images and their edge maps, respectively. Our representation operates at mul-tiple spatial scales and granularities, leading to robust performance. We use 2-class support vector
machine classifiers to identify the presence of normal macula and each of the three pathologies. To fur-ther discriminate sub-types within a pathology, we also build a classifier to differentiate full-thickness
holes from pseudo-holes within the macular hole category. We conduct extensive experiments on a large
dataset of 326 OCT scans from 136 subjects. The results show that the proposed method is very effective
(all AUC > 0.93).
