Summary

Trabeculectomy with 5-fluorouracil (5-FU) significantly improves glaucoma outcomes. This initial surgery led to a 100% success rate, lower intraocular pressure, and reduced medication needs compared to controls.

Area of Science:

  • Ophthalmology
  • Glaucoma Surgery
  • Pharmacology

Background:

  • Glaucoma management often requires surgical intervention.
  • Trabeculectomy is a common surgical procedure for glaucoma.
  • Adjunctive therapies are used to enhance surgical success rates.

Purpose of the Study:

  • To evaluate the effectiveness of trabeculectomy with adjunctive low-dose 5-fluorouracil (5-FU) as an initial surgical procedure for uncomplicated glaucoma.
  • To compare surgical outcomes between patients receiving 5-FU and a control group.

Main Methods:

  • Retrospective study of 52 patients undergoing trabeculectomy with 5-FU and 74 control subjects.
  • Follow-up duration averaged 18.6 months.
  • Success defined as intraocular pressure (IOP) < 21 mmHg; statistical analyses included Wilcoxon test, t test, and Fisher's exact test.

Main Results:

  • Two-year cumulative success rate was 100% in the 5-FU group versus 78.9% in the control group (P=0.01).
  • Mean postoperative IOP at 2 years was significantly lower in the 5-FU group (12.5 mmHg) compared to controls (17.4 mmHg) (P=0.015).
  • Antiglaucoma medication use within 2 years was significantly lower in the 5-FU group (5.8%) than in controls (41.9%) (P<0.0001).

Conclusions:

  • Adjunctive low-dose 5-FU with initial trabeculectomy demonstrates superior efficacy in managing uncomplicated glaucoma.
  • The 5-FU enhanced procedure results in higher success rates, sustained lower IOP, and decreased reliance on postoperative medications.
  • Low-dose 5-FU is a valuable adjunctive agent for initial trabeculectomy in glaucoma patients.
