The purpose of this study was to assess the prevalence and risk factors of each type of cataract among type 2 diabetics in Kinmen, Taiwan. There were 971 type 2 diabetics ascertained from a community-based mass screening between 1991 and 1993. In 1999, a total of 578 (59.5%) patients with type 2 diabetes were examined with an eye screening performed by two senior ophthalmologists using a 45-degree thin slit-lamp biomicroscopy and ophthalmoscopy to examine the lens after dilating the pupils. The overall prevalence, including subjects with or without surgery, was 31.0% (179/578,95% CI : 27.3-34.7%), and had a statistically significant difference for gender (X2=8.78, p=0.003) and age (X2-trend=11.89, p<0.0001). Based on multiple logistic regression, the significant risk factors of all types of cataracts were age (OR=1.16,95% CI : 1.12-1.20), lower diastolic blood pressure (DBP) at baseline (OR=0.47,95% CI : 0.25-0.88), and higher triglyceride at baseline (OR=2.19,95% CI : 1.07-4.45). In conclusion, our results found that in addition to age, lower DBP and higher triglyceride at baseline may increase the risk of prevalent cataracts in type 2 diabetics.
