Research into the risk of Asian-Americans developing glaucoma has been published in the Ophthalmology journal.
The research, which was funded by the US National Eye Institute, reviewed the insurance records of more than 44,000 Asian-Americans aged over 40.
It found that this racial group has a 6.5 per cent risk of developing glaucoma, which is about the same as the risk of US Latinos.
The rate of normal-tension glaucoma NTG was found to be higher in Asian-Americans than in any other racial group.
Leader of the study Dr Joshua Stein, of the Kellogg Eye Center at the University of Michigan, said: "Since NTG won"t be detected by simply measuring intraocular pressure, eye doctors need to assess the status of the optic nerve in patients whose ethnicity makes them more susceptible to this type of glaucoma."
David Wright, chief executive of the International Glaucoma Association, said the UK is likely to see an increase in its number of glaucoma sufferers in the years leading up to 2021.
