    Summary

    Diabetic retinopathy affects nearly half of diabetic patients in Lesotho, with higher risks linked to longer disease duration, hypertension, and neuropathy. Further research is needed for diverse African populations.

    Area of Science:

    • Ophthalmology
    • Endocrinology
    • Public Health

    Background:

    • Diabetic retinopathy is a leading cause of preventable blindness globally.
    • Limited epidemiological data exists for diabetic retinopathy in sub-Saharan Africa.

    Purpose of the Study:

    • To determine the prevalence and associated factors of diabetic retinopathy in diabetic patients in Maseru, Lesotho.
    • To highlight the need for improved epidemiological surveys in Africa.

    Main Methods:

    • Cross-sectional study of 153 consecutive diabetic clinic patients in Maseru, Lesotho.
    • Examination for diabetic retinopathy, including background and proliferative changes.
    • Analysis of associations with sex, hypertension, peripheral neuropathy, and disease duration.

    Main Results:

    • Prevalence of diabetic retinopathy was 47.8%.
    • Background retinopathy (78%) was more common than proliferative changes (22%).
    • Significant associations were found between diabetic retinopathy and hypertension, peripheral neuropathy, and longer diabetes duration.

    Conclusions:

    • Diabetic retinopathy is highly prevalent in this Lesotho cohort.
    • Hypertension, neuropathy, and disease duration are key risk factors.
    • There is a critical need for comprehensive epidemiological studies across diverse African populations.
