Mitomycin trabeculectomy effectively lowers intraocular pressure (IOP) in refractory glaucoma patients. Long-term success rates were high, with 80% achieving complete success and 95% overall success.

Area of Science:

  • Ophthalmology
  • Surgical Innovation
  • Glaucoma Research

Background:

  • Refractory glaucoma presents significant challenges for intraocular pressure (IOP) management.
  • Standard treatments may be insufficient for patients with advanced or complex glaucoma.

Purpose of the Study:

  • To evaluate the surgical outcomes of mitomycin trabeculectomy in patients diagnosed with refractory glaucoma.
  • To assess the long-term efficacy of this surgical intervention.

Main Methods:

  • A cohort of 52 patients (66 eyes) with refractory glaucoma underwent mitomycin trabeculectomy.
  • Mitomycin-C was applied intraoperatively for a single five-minute period.
  • Patient follow-up extended from six to 61 months.

Main Results:

  • Kaplan-Meier analysis indicated a cumulative success probability of 80% +/- 6% at 61 months without medication (complete success).
  • Overall success, including eyes requiring medication, reached 95% +/- 3%.
  • Success was defined as postoperative IOP <= 20 mmHg or >= 20% reduction from baseline for eyes with pre-op IOP >= 24 mmHg.

Conclusions:

  • Mitomycin trabeculectomy demonstrates significant efficacy in reducing IOP for patients with refractory glaucoma.
  • The procedure offers a high probability of long-term IOP control.
  • This surgical approach is a viable option for managing complex glaucoma cases.
