As reported in Eye Care News yesterday, researchers at the University of British Columbia, Vancouver Coastal Health Research Institute and McGill University have discovered that some anti-depressant drugs are associated with an increased risk of developing cataracts.

The study, based on a database of more than 200,000 Quebec residents aged 65 and older, showed statistical relationships between a diagnosis of cataracts or cataract surgery and the class of drugs called selective serotonin reuptake inhibitors or SSRIs, as they are commonly known. The most well known SSRI is Prozac.

The researchers say that these drugs do not cause cataract formation but there is an association between these drugs and the development of cataract. This is the first study to establish this link.

Researchers found patients taking SSRIs were 15% more likely to be diagnosed with cataracts or to have cataract surgery.

The study did not take into consideration one of the main risk factors of cataract formation - smoking.

The study has been published online in the journal Ophthalmology.
