An international consortium of researchers from Asia has shown that three new genes appear to be associated with primary angle closure glaucoma (PACG), a significant cause of blindness worldwide. The research, published in the journal Nature Genetics, reports on a genome wide association study which included 3,771 PACG patients and 18,551 controls recruited across Singapore, Hong Kong, Malaysia, India and Vietnam. The authors of the research suggest that their new findings will provide an improved understanding of the genetic mechanisms responsible for individual susceptibility to PACG. Such information is expected to contribute to identifying and stratifying patients allowing for improved clinical care and management of the disease.
