Senile cataract and glucose intolerance: the Israel Study of glucose Intolerance Obesity and Hypertension (The Israel GOH Study)

Association of "senile" cataract (SC) with glucose intolerance (impaired
tolerance and diabetes) was assessed by sex and age in a random population
sample comprising 930 individuals aged 40-70 yr, who underwent concurrent
oral glucose tolerance test and ophthalmoscopy. The eye examination was
performed without knowledge of the glucose tolerance status. SC was defined
as lens opacification preventing visualization of the eyeground or as
surgical aphakia due to SC. To assess the independent effect of
hyperglycemia, glycosylated hemoglobin (HbA1) was determined in 769
participants. In men, no association was found between SC, glucose
intolerance, and HbA1. In women of all ages, glucose intolerance was
associated with an SC risk ratio of 6.1 (95% confidence limits 3.3-11.1; P
less than 0.001). Furthermore, SC was associated in women with increased
HbA1 independently of the effect of glucose intolerance (P less than 0.01).
These findings confirm the reported association of SC with diabetes
(although unlike the Framingham and HANES population studies, the
association was confined in women), indicate its presence at all degrees of
glucose intolerance, and suggest a possible independent role of
nonenzymatic glycosylation in its pathogenesis.
