Regulating the dose of 5-fluorouracil to prevent filtering bleb scarring.
Repeated doses of 5mg of 5-fluorouracil (5-FU) were injected subconjunctivally in 25 poor-prognosis glaucomatous eyes after filtering surgery to prevent filtering bleb scarring. The frequency (1-2 times a day) and duration (minimum, 7 days) of injections were determined by the degree of the anterior chamber reaction and/or conjunctival hyperemia at the filtering bleb site. Punctate corneal erosions or filaments were not considered a contraindication to continuation of 5-FU treatment. After 12 months, intraocular pressure (IOP) of 16 mmHg or less without medical treatment was found in 19 (76%) eyes. In 16 of these (64%), the IOP was 12 mmHg or less. In two (8%) other eyes, it was 20 mmHg or less with medication. We believe that the comparatively low IOP levels achieved without medical treatment in 76% of the eyes in our study can be attributed in part to our therapeutic approach with 5-FU.
