    Leprosy patients have a high incidence of cataract-induced blindness. This study found that cataracts in lepromatous leprosy patients appear earlier and exhibit specific histopathological changes, suggesting complicated cataract development.

    Area of Science:

    • Ophthalmology
    • Dermatology
    • Pathology

    Background:

    • Leprosy, a chronic infectious disease, can lead to ocular complications, including blindness.
    • Cataracts are a significant cause of vision impairment in the general population and may be exacerbated by leprosy.

    Purpose of the Study:

    • To investigate the prevalence and characteristics of cataract-induced blindness in leprosy patients.
    • To analyze clinical and histopathological features of cataracts in different leprosy types.

    Main Methods:

    • Retrospective analysis of 744 leprosy patients' records.
    • Clinical examination of eyes, including assessment for posterior iris synechiae.
    • Histopathological examination of 24 cataractous lenses.

    Main Results:

    • 8.2% of leprosy patients (61/744) experienced cataract-induced blindness.
    • Cataracts appeared at a younger mean age in lepromatous leprosy (56.4 years) compared to tuberculoid leprosy (63.4 years).
    • Histopathology revealed lens epithelium irregularities (79.2%), posterior iris synechiae (66.7%), and posterior lens epithelium migration (54.2%) in affected lenses.

    Conclusions:

    • Cataracts in leprosy patients are likely complicated, with specific clinical and histopathological findings.
    • The findings suggest a potential link between leprosy type and cataract development, necessitating targeted ophthalmic care for affected individuals.
