Older women with cataracts have a significantly higher risk of death than men, among non-diabetics.
This finding could be due to one or more "sex specific" factors, postulates Dr Darwin Minassian and colleagues at the Institute of Ophthalmology, University College London. Researchers.
Researchers note that the 1985 Framingham Eye Study in the United States found increased mortality in cataract in diabetics, but no such effect was found in the non-diabetic cohort. A second US study in 1995 found that poor survival in non-diabetics was associated with level of severity of nuclear sclerosis (one of three main types of cataract), but no such association was found in diabetics.
A random sample was studied of 1,500 people — around 900 women and 600 men — with cataracts who were aged 65 and older. The cohort was drawn from 17 London family practices monitored over four years. The age and sex specific mortality from various causes was estimated and compared in those with and without cataract.
