Abstract
In some embodiments, a computer-implemented method of automatically predicting progression of age-related macular degeneration is provided. An image analysis computing system receives optical coherence tomography data (OCT data). The image analysis computing system determines an optical attenuation coefficient for each pixel of the OCT data to create optical attenuation coefficient data (OAC data) corresponding to the OCT data. The image analysis computing system determines an area exhibiting geographic atrophy based on at least one of the OCT data and the OAC data. The image analysis computing system measures one or more attributes within an adjacent area that is adjacent to the area exhibiting geographic atrophy, and the image analysis computing system determines a predicted enlargement rate based on the one or more attributes within the adjacent area.
