Eye-opening research

A UNIVERSITY of Michigan study has found that having the ‘double whammy’ of diabetes and hypertension causes a dramatic increase in the risk of developing open-angle glaucoma (OAG).

Researchers reviewed records of more than two million people, aged 40 or older, who visited an eye care provider in 2001–07. 

Having diabetes increased the risk for OAG by 35%, while hypertension caused a 17% increased risk. For those patients with both diabetes and hypertension, the risk of developing OAG was increased by 48%.

Interestingly, the study also showed that hyperlipidaemia reduced OAG risk by 5%. Researchers are trying to evaluate whether this finding is due to having hyperlipidaemia itself, and/or whether the medications used affect OAG risk.
