Mitomycin was more effective and safer than fluorouracil as an adjunct to trabeculectomy surgery for glaucoma patients with poor prognosis. Mitomycin achieved better intraocular pressure control with fewer corneal complications.

Area of Science:

  • Ophthalmology
  • Surgical Innovation
  • Glaucoma Research

Background:

  • Glaucoma management often requires surgical intervention, such as trabeculectomy.
  • Eyes with poor surgical prognosis present unique challenges for achieving successful intraocular pressure reduction.
  • Adjunctive therapies are crucial for enhancing trabeculectomy outcomes in complex cases.

Purpose of the Study:

  • To compare the efficacy and safety of mitomycin versus fluorouracil as adjuncts to trabeculectomy.
  • To evaluate outcomes in patients with glaucoma and poor surgical prognosis.
  • To determine the optimal adjunctive agent for improving trabeculectomy success rates.

Main Methods:

  • Prospective, randomized study involving 32 eyes of 32 patients.
  • Patients were allocated to receive either mitomycin (once during surgery) or fluorouracil (10 injections post-surgery).

  • Intraocular pressure and complications were monitored over a 7-12 month follow-up period.

    • Main Results:

    • Mitomycin achieved a target intraocular pressure (≤20 mm Hg) in 88% of eyes, compared to 47% with fluorouracil.
    • Corneal complications were significantly lower in the mitomycin group (12%) versus the fluorouracil group (53%).
    • Other complication rates were similar between the two treatment groups.

    Conclusions:

    • Mitomycin demonstrates superior efficacy in achieving target intraocular pressure post-trabeculectomy compared to fluorouracil.
    • Mitomycin offers a better safety profile, with a lower incidence of corneal complications.
    • Mitomycin is a preferred adjunctive agent for trabeculectomy in glaucoma patients with poor surgical prognosis.
