Postoperative subconjunctival 5-fluorouracil (5-FU) injections may improve glaucoma filtering surgery success rates in high-risk patients. This pilot study analyzed outcomes in 155 patients, finding varied success rates across different glaucoma types.

Area of Science:

  • Ophthalmology
  • Glaucoma Surgery
  • Surgical Outcomes

Background:

  • Glaucoma filtering surgery is a common treatment for advanced glaucoma.
  • High-risk patients often experience lower success rates with traditional filtering surgery.
  • Postoperative adjunctive therapies are explored to enhance surgical outcomes.

Purpose of the Study:

  • To evaluate the efficacy and safety of subconjunctival 5-fluorouracil (5-FU) injections following glaucoma filtering surgery.
  • To assess the impact of 5-FU on surgical success rates in different glaucoma patient subgroups.
  • To identify potential complications associated with 5-FU augmented glaucoma surgery.

Main Methods:

  • Life-table analysis of surgical outcomes in 155 patients undergoing first-eye glaucoma filtering surgery.

  • Inclusion of postoperative subconjunctival 5-FU injections as an adjunctive therapy.
  • Categorization of patients based on glaucoma type (neovascular vs. non-neovascular) and surgical history (aphakia, prior failed surgery).
  • Complication assessment and Cox Model regression analysis to identify factors influencing success.

    • Main Results:

    • Success rates at 3 years were 63% for non-neovascular glaucoma in aphakia, 75% for non-neovascular glaucoma after failed surgery, and 68% for neovascular glaucoma.
    • Common complications included corneal epithelial defects (55.5%) and conjunctival wound leaks (36.8%).
    • Cox Model analysis did not find correlations between success and age, race, procedure type, or 5-FU dose.

    Conclusions:

    • Postoperative subconjunctival 5-FU may enhance the success rate of glaucoma filtering surgery in selected high-risk patients.
    • While 5-FU shows potential benefits, a significant complication profile necessitates careful consideration.
    • Further research is warranted to optimize the use of 5-FU in glaucoma surgery.
