Surgical scars after trepanotrabeculectomy

    Summary

    Trabeculectomy surgery results in favorable scar formation in 80% of patients, maintaining eye integrity and normalizing intraocular pressure long-term. This indicates trabeculectomy is a superior glaucoma treatment.

    Area of Science:

    • Ophthalmology
    • Surgical Innovation

    Background:

    • Glaucoma surgery aims to reduce intraocular pressure.
    • Trabeculectomy is considered superior to older filtering operations.
    • Postoperative scar characteristics are crucial for surgical success.

    Purpose of the Study:

    • To evaluate the long-term characteristics of surgical scars after primary trepanotrabeculectomy.
    • To correlate scar appearance with surgical outcomes and eye integrity.

    Main Methods:

    • Follow-up study of surgical scars in 73 eyes.
    • Observation period ranged from two to eight years.
    • Assessment of scar appearance, conjunctival coverage, avascular areas, and external filtration.

    Main Results:

    • 80% of eyes (56/73) developed flat scars with normal conjunctiva.
    • No avascular cystic areas or external filtration were observed in successful cases.
    • Normalized intraocular tension was achieved in eyes with favorable scars.
    • Scars remained stable and did not compromise ocular integrity over time.

    Conclusions:

    • Primary trepanotrabeculectomy yields favorable, stable scar formation in most patients.
    • These scar characteristics are associated with successful long-term intraocular pressure control.
    • Trabeculectomy's superior outcomes are supported by the positive long-term scar profile.
