"The key to reducing the personal and public health impact of glaucoma is early diagnosis and treatment to slow the loss of sight. Discoveries such as today's, which follows on our previous landmark findings in exfoliation glaucoma, are important because we can fold them directly into tests to target screening and to detect and treat more disease earlier. Moreover, among Chinese this latest SNP alone can define a small fraction of the population that should be very carefully screened. This underscores the value of being able to systematically analyze the impact of genetic risk factors across continental ancestries. Not only are these markers medically useful, they also tell us a bit about evolution and the spread of humanity across the globe," said Kari Stefansson, deCODE's Executive Chairman and President of Research and senior author of the study.

The authors would like to thank the more than 40,000 people who participated in this study, both glaucoma patients and control subjects. The paper, "Common variants near CAV1 and CAV2 are associated with primary open-angle glaucoma," is published online in Nature Genetics at nature/ng and will appear in an upcoming print edition of the journal.
