1. A method for monitoring a retina of a subject, comprising the steps of:
obtaining a set of retina template images of a retina;
matching a retina template image in the set to a retina baseline image of the retina at least by:
applying dimension reduction to the retina baseline image and the retina template image; and
generating a registered retina template image at least by registering the retina template image to at least a portion of the retina baseline image, wherein the retina baseline image captures a wider field of view than the retina template image; and
registering the retina template image as a registered retina template image at least based at least in part upon at least a portion of the retina baseline image, wherein the retina baseline image comprises a wider field of view than the retina template image; and
detecting a change in a characteristic pertaining to the retina or a subject of the retina based at least in part upon a comparison between the registered retina template image and the retina baseline image.
