Body weight "may affect glaucoma risk"

A person"s body weight may play a role in their chances of developing glaucoma, it has been claimed.

According to a new study conducted by experts at Massachusetts Eye and Ear Infirmary, higher body weight, or body mass index (BMI), is not associated with higher risk of primary open-angle glaucoma (POAG).

Rather, in women, a higher BMI is significantly linked to reduced risk for a variant of POAG known as normal tension glaucoma (NTG).

Dr Louis Pasquale, who led the research, commented: "Understanding the mechanisms that drive BMI and other body composition factors in relation to POAG might help us solve some mysteries connected with this complex illness."

It follows research carried out by Johns Hopkins University in Baltimore which found that people who eat one or more servings of oily fish a week are 60 per cent less likely to have advanced age-related macular degeneration.
