The latest investigations into a promising new genetic test for glaucoma - the leading cause of blindness worldwide - has found it has the ability to identify 15 times more people at high risk of glaucoma than an existing genetic test. The study, just published in JAMA Ophthalmology, builds on a long-running international collaboration between Flinders University and the QIMR Berghofer Medical Research Institute and other research partners around the world to identify genetic risk factors for glaucoma.
