Intra-operative use of 5-fluorouracil in glaucoma filtering surgery
1Department of Ophthalmology, Royal Hallamshire Hospital, Sheffield, U.K.
Abstract:
This study reviews the outcome of 14 eyes considered to be at risk of surgical failure undergoing trabeculectomy with 5-Fluorouracil (5-FU). The antimetabolite was administered intra-operatively by placing a surgical sponge soaked in 5-FU (25 mg/ml) directly on the sclera under the conjunctival flap for 5 minutes. All eyes showed a reduction in intraocular pressure (IOP) at a mean follow-up of 18.5 weeks, and only one eye required topical antiglaucoma medication. Mean IOP reduction at final follow-up was 43.1%. No eyes showed any corneal problems associated with the intra-operative use of 5-FU. These results suggest that the intra-operative use of 5-Fluorouracil is an effective way of improving surgical success in at risk eyes. The early complications appear to be less than those associated with post-operative subconjunctival injections of 5-FU, but the long-term differences are still to be shown.
Insights
Intra-operative use of 5-Fluorouracil (5-FU) during trabeculectomy significantly reduced intraocular pressure in high-risk eyes. This method appears effective and safe, with fewer early complications than post-operative 5-FU injections.
Area of Science:
- Ophthalmology
- Glaucoma Surgery
- Surgical Innovation
Background:
- Trabeculectomy is a common glaucoma surgery.
- High-risk eyes often face surgical failure.
- 5-Fluorouracil (5-FU) is used to prevent scarring and improve success rates.
Purpose of the Study:
- To evaluate the efficacy and safety of intra-operative 5-Fluorouracil (5-FU) application during trabeculectomy.
- To assess the impact of 5-FU on intraocular pressure (IOP) reduction in high-risk eyes.
Main Methods:
- Trabeculectomy was performed on 14 high-risk eyes.
- A surgical sponge soaked in 5-FU (25 mg/ml) was applied intra-operatively to the sclera under the conjunctival flap for 5 minutes.
- Intraocular pressure (IOP) and complications were monitored.
Main Results:
- All eyes achieved a reduction in IOP at a mean follow-up of 18.5 weeks.
- Mean IOP reduction was 43.1% at final follow-up.
- Only one eye required additional topical antiglaucoma medication.
- No corneal complications were observed.
Conclusions:
- Intra-operative 5-FU application is an effective method to enhance surgical success in trabeculectomy for at-risk eyes.
- Early complication rates appear lower compared to post-operative subconjunctival 5-FU injections.
- Long-term outcomes require further investigation to confirm sustained efficacy and safety.
