Disease classification of macular Optical Coherence Tomography scans using deep learning software: validation on independent, multi-centre data

07/11/2019 ∙ by Kanwal K. Bhatia, et al. ∙ 1

Purpose: To evaluate Pegasus-OCT, a clinical decision support software for the identification of features of retinal disease from macula OCT scans, across heterogenous populations involving varying patient demographics, device manufacturers, acquisition sites and operators. Methods: 5,588 normal and anomalous macular OCT volumes (162,721 B-scans), acquired at independent centres in five countries, were processed using the software. Results were evaluated against ground truth provided by the dataset owners. Results: Pegasus-OCT performed with AUROCs of at least 98 in the detection of general macular anomalies. For scans of sufficient quality, the AUROCs for general AMD and DME detection were found to be at least 99 98 Conclusions: The ability of a clinical decision support system to cater for different populations is key to its adoption. Pegasus-OCT was shown to be able to detect AMD, DME and general anomalies in OCT volumes acquired across multiple independent sites with high performance. Its use thus offers substantial promise, with the potential to alleviate the burden of growing demand in eye care services caused by retinal disease.
