PURPOSE: To examine the prevalence of @entity6 and the relationship between @entity6 and systemic risk factors. METHODS: A cross sectional study of @entity6 was conducted on 1,826 eyes of 913 randomly selected @entity1 with @entity164 2 @entity6 in 9 central hospitals in Aomori Prefecture and the surrounding district. Retinopathy levels and @entity1020 were assessed by binocular funduscopy, fundus photography and, if necessary, by @entity941 angiography. Multiple logistic regression analysis was performed to determine independent effects of systemic risk factors on @entity6 . RESULTS: The prevalence of background @entity989 was 31%, of @entity989 5%, and of @entity989 5% in all @entity1 . However, in 3 hospitals in which the @entity1 were routinely examined by @entity941 angiography, background @entity989 was found to be present in 60%, @entity989 in 5%, and prolifertive @entity989 in 7%. @entity1020 was found in 8% of @entity6 @entity1 and the prevalence was 11% in the eyes with background @entity989 , 40% with @entity989 , and 50% with @entity989 . Multiple logistic regression analysis showed that @entity989 was significantly associated with duration of @entity6 , methods of @entity6 control, @entity101 , @entity8 , and @entity16 . CONCLUSION: The detection rate of background @entity6 by @entity941 angiography was twice as sensitive as that by binocular funduscopy and fundus photography. The prevalence of @entity1020 increases with the progression of @entity989 . Several systemic risk factors have significant association with @entity6 and @entity1020 .
