A non-stereo
fundus image is used to obtain a plurality of
glaucoma indicators. Additionally,
genome data for the subject is used to obtain
genetic marker data relating to one or more genes and / or SNPs associated with
glaucoma. The
glaucoma indicators indicators and
genetic marker data are input into an adaptive model operative to generate an output indicative of a risk of glaucoma in the subject. In combination, the genetic indicators and
genome data are more informative about the risk of glaucoma than either of the two in isolation. The adaptive model may be a two-stage model, having a first stage in which individual genetic indicators are combined with respective portions of the
genome data by first adaptive model modules to form respective first outputs, and a second stage in which the first outputs are combined by a second adaptive mode. Texture analysis is performed on the fundus images to classify them based on their quality, and only images which are determined to meet a quality criterion are subjected to an analysis to determine if they exhibit glaucoma indicators. Also, the images are put into a standard format. The
system may include estimating the position of the optic cup by combining results from multiple optic cup segmentation techniques. The
system may include estimating the position of the
optic disc by applying
edge detection to the funds image, excluding edge points that are unlikely to be
optic disc boundary points, and estimating the position of an
optic disc by fitting an
ellipse to the remaining edge points.
