    Summary

    Subconjunctival 5-Fluorouracil (5-FU) aided glaucoma surgery in a pilot study. This treatment improved intraocular pressure control in eyes with poor surgical prognoses, with acceptable side effects.

    Area of Science:

    • Ophthalmology
    • Glaucoma Surgery
    • Pharmacology

    Background:

    • Glaucoma filtering surgery can have poor outcomes in certain patient groups.
    • Controlling intraocular pressure (IOP) is crucial for preventing further vision loss.

    Purpose of the Study:

    • To evaluate the efficacy and safety of subconjunctival 5-Fluorouracil (5-FU) in improving IOP control after glaucoma filtering surgery.
    • To assess the impact of 5-FU on visual acuity and identify potential side effects.

    Main Methods:

    • A pilot study involving subconjunctival injection of 5-FU post-glaucoma filtering surgery.
    • Inclusion of eyes with poor surgical prognoses, including aphakic, neovascular glaucoma, and post-unsuccessful filtering phakic eyes.
    • Monitoring of IOP, visual acuity, and postoperative complications.

    Main Results:

    • High success rates in achieving target IOP (≤21 mmHg) across different glaucoma subtypes (79% aphakic, 69% neovascular, 89% phakic).
    • Visual acuity remained stable or improved in a majority of eyes (94% aphakic, 62% neovascular, 67% phakic).
    • Common side effects included corneal epithelial defects (45%) and wound leaks (41%), with minimal need for intervention.

    Conclusions:

    • Postoperative subconjunctival 5-FU appears to enhance IOP control in glaucoma patients with poor surgical prognoses.
    • Further confirmation through a randomized clinical trial is warranted to validate these promising findings.
