    Area of Science:

    • Ophthalmology
    • Endocrinology
    • Public Health

    Background:

    • Diabetic retinopathy (DR) is a leading cause of vision loss.
    • Understanding visual acuity outcomes in different diabetic onset groups is crucial for public health initiatives.

    Purpose of the Study:

    • To assess and compare visual acuity and causes of visual impairment in younger-onset versus older-onset diabetic retinopathy patients.
    • To identify risk factors associated with visual impairment in these populations.

    Main Methods:

    • Population-based study in southern Wisconsin.
    • Examined two groups: younger onset (diagnosed before 30, insulin-dependent) and older onset (diagnosed at 30+).
    • Best corrected visual acuity measured using the Early Treatment of Diabetic Retinopathy Study protocol.

    Main Results:

    • Younger onset: 1.4% moderate visual impairment, 3.6% legal blindness. Older onset: 3.0% moderate visual impairment, 1.6% legal blindness.
    • Risk factors for visual impairment included older age at examination, longer diabetes duration, proliferative retinopathy, and cataracts in both groups.
    • Diabetic retinopathy was the primary cause of severe vision loss in 86% of younger-onset and 33% of older-onset individuals.

    Conclusions:

    • Younger-onset diabetes patients face a higher risk of severe visual impairment and blindness due to diabetic retinopathy.
    • Early detection and management of diabetic retinopathy are critical for preserving vision across all diabetic patient groups.
    • Senile cataracts and proliferative diabetic retinopathy are significant contributors to vision loss in both younger and older onset diabetic populations.
