Abstract

BACKGROUND:

Visual disabilities due to diabetes are on the rise, especially in urban areas of developing countries. Proper health planning will need evidence-based information.

STUDY DESIGN AND METHODS:

We estimated the prevalence and identified the determinants of eye complications among persons with diabetes screened in Ahmedabad, India, during 2007-2008. This was a review of the data from a health institution-based project. Physicians collected information on diabetes, and ophthalmologists examined the patients for visual acuity, diabetic retinopathy (DR), glaucoma, and cataracts. World Health Organization-recommended grading of DR was used. Frequencies, prevalence, and 95% confidence interval (CI) values were calculated.

RESULTS:

Of 40,919 persons who we examined for diabetes, 9,246 (66.6%) persons knew that they had diabetes, whereas 4,641 (33.4%) persons were detected with diabetes for the first time. The prevalence of DR, early cataract, and glaucoma among those who knew that they had diabetes was 14.6% (95% CI 13.9-15.3), 44.4% (95% CI 43.4-45.4), and 5.4% (95% CI 4.9-5.9), respectively. The prevalence of DR among persons with diabetes (new and old) was 10.1% (95% CI 9.6-10.6). Although poor vision was positively associated with DR (chi2 = 706), 40% of those with DR had vision better than 20/60. Male sex (odds ratio [OR] = 1.31), longer duration of diabetes (chi2 = 1,808), hypertension (OR = 1.13), good sugar control (OR = 0.09), and nephropathy (OR = 2.16) were the factors associated with DR. Regression analysis suggested that longer duration of diabetes and poor control of diabetes were the predictors of DR.

CONCLUSIONS:

The prevalence of DR was low. Long duration of diabetes, poor control of blood sugar, presence of nephropathy, and hypertension were associated with DR. Good vision could mislead about the severity of DR.
