Singapore, Jul 28, 2009: Commonly used blood pressure drugs such as beta blockers and ACE inhibitors can increase cataract formation, Australian researchers say.

 

In a report published in British Journal of Ophthalmology, researchers said if drugs cause cataract, they have to be removed surgically.

However it is unclear if high BP itself can cause cataract formation in eyes. A

The study was done by G L Kanthan, J J Wang, E Rochtchina and P Mitchell, who are based at University of Sydney, Center for Vision Research, Westmead Millennium Institute.

The researchers examined 3654 persons above the age of 49 at baseline and 2454 were re-examined after 5 and/or 10 years. Interviewer-administered questionnaires collected information on use of medications. Lens photographs were taken at each visit and graded. Associations between antihypertensive medications and the 10-year incidence of cataract and cataract surgery were assessed.

Cataract is an formation around lens of the eye that makes vision improper and is common among elderly people globally and has to be removed surgically.

Beta blockers are used reduce high blood pressure and is also applied to the eye to treat glaucoma.
