  1. Population based assessment of diabetic retinopathy in an urban population in southern India.

    Article - En anglais

    Aim-To assess the prevalence of diabetic retinopathy and the visual impairment caused by it in an urban population in southern India in order to determine its public health significance.

    Methods-2522 subjects (85.4% of those eligible), a representative sample of the population of Hyderabad city in southern India, underwent interview and detailed dilated eye examination during 1996-7 as part of the Andhra Pradesh Eye Disease Study.

    Results

    124 subjects, all >=30 years old, reported that they had diabetes, an age-sex adjusted prevalence of 7.82% (95% confidence interval (CI) 5.76-9.88%) in this age group.

    Diabetes was diagnosed at age >=30 years in all but two subjects.

    The duration since diagnosis of diabetes was<10 years in 75.6% and >=1 5 years in 6.7%. Diabetic retinopathy was present in 28 subjects, 1.78% (95% CI 1.09-2.48%) of those >=30 years old.

    Most of the diabetic retinopathy was of the mild (50%) or moderate (39.3%) non-proliferative type ; one subject (3.6%) had proliferative retinopathy.

    Multiple logistic regression revealed that the odds of having diabetic retinopathy were significantly higher in those >=50 years than in those 30-49 years old (odds ratio 7.78,95% CI 2.92-20.73).

    Three subjects had visual impairment between 6112 and 6/38 in either eye due to diabetic retinopathy, 0.19% (95% CI 0-0.41%) of those >=30 years old.

    Conclusion-Visual impairment due to diabetic retinopathy was relatively uncommon in this urban Indian population in 1996-7. (...)
