MedPage Today reported, Women with higher body mass index and weight were at reduced risk of developing certain forms of glaucoma, according to a study published in the August issue of Ophthalmology.
In fact, for each unit of body mass index, participants in the giant Nurses' Health Study showed a 6% reduction (95% CI 2% to 9%) in the rate of developing primary open-angle glaucoma with an intraocular pressure of 21 mm Hg or less at diagnosis (so-called normal tension). The study authors theorized that some measure linked to adiposity or lean mass that is under sex hormonal influences may protect against the development of primary open-angle glaucoma.
According to the researchers' report online in Ophthalmology, no relationship between body composition measures and glaucoma risk was found for men in another large cohort, the Health Professionals Follow-Up Study. Nor did BMI or other anthropometric parameters in Nurses' Health Study participants affect the risk of primary open-angle glaucoma with higher intraocular pressure.
