Limbal trephination: a twenty-year follow-up

H S Sugar

    International Ophthalmology Clinics
    |January 1, 1981
    PubMed
    Summary

    Limbal trephination showed excellent results for glaucoma patients over 35, especially those aged 50+, with chronic open-angle and angle-closure glaucoma. Younger patients and those with inflammatory secondary glaucoma experienced poor outcomes.

    Area of Science:

    • Ophthalmology
    • Surgical Interventions
    • Glaucoma Management

    Background:

    • Glaucoma is a leading cause of irreversible blindness worldwide.
    • Chronic open-angle glaucoma (COAG) and chronic angle-closure glaucoma (CACG) are prevalent forms requiring effective management.
    • Limbal trephination is a surgical technique used in glaucoma treatment.

    Purpose of the Study:

    • To evaluate the efficacy of limbal trephination in different patient demographics and glaucoma types.
    • To identify patient factors associated with successful limbal trephination outcomes.

    Main Methods:

    • Retrospective analysis of patients undergoing limbal trephination.
    • Stratification of results based on age groups (under 35, 35-49, 50+).
    • Categorization of glaucoma types including COAG, CACG, and secondary glaucoma, with specific attention to inflammatory associations.

    Main Results:

    • Excellent outcomes observed in patients aged 35 and above, particularly in the 50+ age group.
    • High success rates noted for chronic open-angle and chronic angle-closure glaucoma.
    • Poor results were documented in younger patient cohorts (<35 years).
    • Significantly worse outcomes were seen in patients with secondary glaucoma, especially when linked to ocular inflammation.

    Conclusions:

    • Limbal trephination is a highly effective surgical option for older adults (50+) with chronic open-angle and chronic angle-closure glaucoma.
    • Age and the presence of secondary glaucoma, particularly inflammatory types, are critical factors influencing limbal trephination success.
