Mini-trabeculectomy, a glaucoma surgery without radial incisions, proved effective and safe in lowering intraocular pressure for over 25 months. This initial surgical approach offers potential advantages compared to standard trabeculectomy.

Area of Science:

  • Ophthalmology
  • Glaucoma Surgery
  • Surgical Outcomes

Background:

  • Glaucoma management often requires surgical intervention when medical therapy is insufficient.
  • Standard trabeculectomy is a common surgical procedure, but alternative techniques are being explored.
  • Mini-trabeculectomy, a modification without radial incisions, aims to provide similar efficacy with potentially fewer complications.

Purpose of the Study:

  • To evaluate the surgical outcomes of mini-trabeculectomy as an initial surgical treatment for medically uncontrolled glaucoma.
  • To assess the efficacy and safety of mini-trabeculectomy at a minimum of 12 months follow-up.

Main Methods:

  • A prospective, institutional study involving 41 eyes of patients aged 40+ with medically uncontrolled glaucoma.
  • Mini-trabeculectomy involved a fornix-based conjunctival flap, sclerostomy, and a sclerocorneal tunnel without radial incisions.

  • Thirty-six eyes completed at least 12 months of follow-up, with a mean follow-up of 25 months.

    • Main Results:

    • Preoperative intraocular pressure (IOP) averaged 30.2 mmHg with 3.0 medications.
    • Postoperatively, 97.2% of eyes achieved target IOP (mean 16.0 mmHg) with significantly fewer medications (0.8).
    • Complications included early aqueous leakage (5.4%) and cataract progression (2.7%).

    Conclusions:

    • Mini-trabeculectomy demonstrated efficacy and relative safety in lowering IOP for glaucoma patients.
    • The procedure may offer clinical and technical advantages over standard trabeculectomy.
    • Further controlled studies are needed to validate these findings.
