1. A computer-implemented method for generating or analyzing fundus drawings, the method comprising: receiving, by a computing device, data indicative of a fundus image; identifying, by the computing device, one or more image features indicative of a condition or a label associated with the fundus image; generating, by the computing device, a fundus drawing based on the one or more image features; associating, by the computing device, a classifier with the identified image features; adding, by the computing device, the classifier to a collection of classifiers; and determining, by the computing device, recommended labels for the fundus drawing or the fundus image based on previously associated labels, the associated classifier, and the collection of classifiers.
