Summary

Subconjunctival 5-fluorouracil (5-FU) injections significantly improved outcomes for glaucoma patients with poor surgical prognoses undergoing trabeculectomy. This treatment enhanced bleb formation and maintained lower intraocular pressure (IOP) long-term.

Area of Science:

  • Ophthalmology
  • Glaucoma Surgery
  • Pharmacological Adjuncts

Background:

  • Trabeculectomy is a common glaucoma surgery.
  • Poor surgical prognosis can lead to suboptimal outcomes.
  • Identifying adjuncts to improve trabeculectomy success is crucial.

Purpose of the Study:

  • To evaluate the efficacy of subconjunctival 5-fluorouracil (5-FU) injections.
  • To assess the impact of 5-FU on bleb formation and intraocular pressure (IOP).
  • To determine the effect of 5-FU on trabeculectomy success rates in patients with poor surgical prognosis.

Main Methods:

  • Prospective study of 18 glaucoma patients (20 eyes) with poor surgical prognosis receiving 5-FU subconjunctival injections post-trabeculectomy.
  • Comparison with a historical control group of 24 eyes undergoing repeat trabeculectomy without 5-FU.

  • Life table analysis for success probability and IOP monitoring over 18 months.

    • Main Results:

    • The 5-FU treated group showed a 68.2% success probability at 18 months.
    • The untreated group had a success probability as low as 10% by 14 months.
    • The difference in success rates was statistically highly significant (P < 0.001).

    Conclusions:

    • Postoperative subconjunctival 5-FU injection improves bleb formation and IOP control.
    • 5-FU enhances the long-term success of trabeculectomy in high-risk glaucoma patients.
    • 5-FU is a valuable adjunct for improving surgical outcomes in refractory glaucoma.
