Effectiveness of trabeculectomy in glaucoma.

P G Watson, F Barnett

    American Journal of Ophthalmology
    |May 1, 1975
    PubMed
    Summary

    Trabeculectomy effectively controlled intraocular pressure in most patients, with over 97% achieving long-term pressure control. This glaucoma surgery demonstrated significant benefits with minimal complications.

    Area of Science:

    • Ophthalmology
    • Surgical Procedures

    Background:

    • Glaucoma management requires effective methods to lower intraocular pressure.
    • Trabeculectomy has been a cornerstone surgical treatment for glaucoma.

    Purpose of the Study:

    • To evaluate the long-term efficacy and safety of trabeculectomy.
    • To assess intraocular pressure control and complication rates following trabeculectomy.

    Main Methods:

    • A follow-up study of 90 eyes in 60 patients who underwent trabeculectomy between 1967 and 1972.
    • Analysis of intraocular pressure control, need for further medication or surgery, and complication rates.

    Main Results:

    • Initial intraocular pressure control was achieved in 84% of eyes, with eventual control in over 97%.
    • Subconjunctival drainage blebs formed in 91% of eyes.
    • Trabeculectomy resulted in a significant reduction in intraocular pressure (P < .001) and increased aqueous outflow facility.
    • Only 11% required further medication and 5.5% required further surgery.
    • The procedure was associated with minimal major complications and maintained anterior chamber integrity.

    Conclusions:

    • Trabeculectomy is a highly effective surgical procedure for long-term intraocular pressure control in glaucoma patients.
    • The surgical technique offers significant benefits with a low rate of complications and need for subsequent interventions.
    • Trabeculectomy can be modified to manage intraoperative challenges like peripheral anterior synechiae.
