[5-Fluorouracil in trabeculectomy: preliminary report].

Subconjunctival 5-FU injections were used as an adjunctive therapy in trabeculectomy for high risk glaucoma patients. We injected 5 mg once a day for five to seven days as a routine treatment. For the first 10 eyes, the injections were started immediately after the operation. However, for the remaining 9 eyes, the injections began 24 to 48 hours postoperative. If the appearance of the bleb was not prominent or enriched in vascularity, the duration of the injections should be extended to 10 to 14 days. At least 8 months of follow-up were available for 19 eyes, including aphakic glaucoma, 8 eyes; neovascular glaucoma, 2 eyes; previous failed filter, 6 eyes; total collapse of the anterior chamber with leucoma adherence, 1 eye; glaucoma due to mesodermal dysgenesis, 1 eye; and juvenile glaucoma, 1 eye (whose fellow eye had received twice failed filtering procedures). The results revealed a success rate of 79% (intraocular pressure below 22mmHg with or without topical medication). The success rate for aphakic glaucoma was 63% (5/8), for neovascular glaucoma 100% (2/2) and for the failed filters 83% (5/6). We also presume that 5-FU injections would be effective in the treatment of to abnormally marked fibrous proliferations caused by age factors. The complications related to the use of 5-FU include corneal epithelial defect 4/9 (21%), conjunctival leak 3/9 (16%), subconjunctival hematoma 1/19 (5%), and conjunctival sterile ulcer 1/19 (5%).
