Filtering surgery with 5-fluorouracil: a second course

In five glaucoma patients, a previous filtering surgery that was followed by sub-conjunctival injections of 5-Fluorouracil (5-FU) failed, due to filtering bleb scarring. A repetition of the filtering surgery with subsequent sub-conjunctival injections of 5 mg of 5-FU, administered once daily for 8-14 days, was undertaken. At the end of 6-19 months of follow-up, IOP levels in all five eyes were 20 mmHg or less with medication. A repeated course of filtering surgery plus 5-FU treatment seems to be a favourable surgical option in refractory glaucoma.
