Subconjunctival 5-fluorouracil (5-FU) injections significantly enhance trabeculectomy success rates for various glaucoma types. However, 5-FU showed no significant benefit in primary open-angle glaucoma patients over 70.

Area of Science:

  • Ophthalmology
  • Glaucoma Surgery
  • Pharmacology

Background:

  • Trabeculectomy is a common glaucoma surgery.
  • Subconjunctival 5-fluorouracil (5-FU) is used to improve surgical outcomes.
  • The efficacy of 5-FU in different glaucoma types and age groups requires further investigation.

Purpose of the Study:

  • To evaluate the effect of subconjunctival 5-FU on trabeculectomy outcomes.
  • To compare success rates between glaucoma types and age groups.
  • To assess the impact of 5-FU compared to historical controls without 5-FU.

Main Methods:

  • Retrospective study of 205 eyes from 168 patients.
  • Life table analysis of surgical outcomes.
  • Comparison with historical data of trabeculectomy without 5-FU.

Main Results:

  • Trabeculectomy with 5-FU showed higher success rates at 30 months: primary open-angle glaucoma (93.6%), secondary glaucoma (88.9%), and refractory glaucoma (72.2%).
  • Historical controls without 5-FU had lower success rates: 60.0%, 35.5%, and 18.0% respectively.
  • No statistically significant improvement was observed with 5-FU in primary open-angle glaucoma patients over 70 years old.

Conclusions:

  • Subconjunctival 5-FU significantly improves trabeculectomy success rates across various glaucoma types.
  • The use of 5-FU may be indicated for specific glaucoma subtypes and patient demographics.
  • Further research is needed to establish optimal dosage and indications for 5-FU in glaucoma surgery.
