Visualization of a deep learning model\u2019s point of interest (POI) may reveal unexpected areas associated with diseases such as age\u2010related macular degeneration (AMD). In this study, a deep learning model coined OptiNet was trained to identify AMD in spectral\u2010domain optical coherence tomography (SD\u2010OCT) macular scans and the anatomical distribution of POIs was studied.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>The deep learning model OptiNet was trained and validated on two data sets. Data set no. 1 consisted of 269 AMD cases and 115 controls with one scan per person. Data set no. 2 consisted of 337 scans from 40 AMD cases (62 eyes) and 46 from both eyes of 23 controls.
