More progress with promising new genetic test for glaucoma The latest investigation 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, published in JAMA Ophthalmology, builds on a long-running international collaboration between Flinders University, the QIMR Berghofer Medical Research Institute and other research partners around the world to identify genetic risk factors for glaucoma. Early diagnosis of glaucoma can lead to vision-saving treatment, and genetic information can potentially give us an edge in making early diagnoses, and better treatment decisions."
