Agency for Science Technology and Research, Singapore Health Services, Blakely Sokoloff Taylor & Zafman, September 20, 2016: US09445716

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 and genetic marker data are input into an adapti ...
