    Abstract:
    PURPOSE: To observe the long term success of antimetabolites used in glaucoma filtering surgery in eyes with high risc of failure. MATERIAL AND METHOD: Two groups of patients undergone trabeculectomy with the use of antimetabolites 5-Fluorouracil (5-FU) and Mitomycin C (MMC) are included in this retrospective study. 5-FU was administered postoperatively 1-10 times in the dose of 5 mg/ml in subconjunctival injection on 32 eyes. Follow up time ranged from 8 months to 9 years. Mitomycin C was administered intraoperatively in the dose of 0.2 mg/ml, on subconjunctival sponge with application time from 3 to 5 minutes on 15 eyes. Follow up time ranged from 7 month to 4.5 years. RESULTS: Intraocular pressure (IOP) before operation with the use of 5-FU was in average 28.8 mmHg (22-50 mmHg) at the end of therapy with 5-FU was 17.6 mmHg (10-30 mmHg) and in the last examination was on average 19.5 mmHg (14-28 mmHg). IOP before operation with the use of MMC was in average 30.3 mmHg (22-40 mmHg), the seventh day after administration of MMC 12.7 mmHg (6-20 mmHg) and in the last examination was in average 18 mmHg (9-28 mmHg). During the long term observation of IOP values in the 5-FU group there was 79.2% success and in the MMC group there was 83.3% success (IOP up to 20 mmHg with or without therapy). Decrease of IOP was statistically significant. CONCLUSION: Antimetabolites improve the success of filtering surgery in high risc glaucomas. The long term follow up shows that failure of filtration in these types of glaucomas is still a serious clinical problem.
