title: Effects of beta-aminopropionitrile after glaucoma filtration surgery: pilot human trial.
abstract: Beta-aminopropionitrile fumarate, an inhibitor of collagen cross-linking, was used topically in patients after filtration surgery for difficult cases of glaucoma (aphakic, repeat surgery, neovascular). Twenty-three patients received the drug for a total treatment period of three months following surgery. The mean preoperative intraocular pressure was 40.0 +/- 14.1 mm Hg (mean +/- standard deviation). The mean postoperative pressure was 19.0 +/- 8.9 mm Hg, with the mean follow-up at 26.4 +/- 11 weeks. The overall success rate was 74%, with success being defined as an intraocular pressure of 22 mm Hg or less at the last visit. Side effects consisted primarily of stinging immediately after the medication was applied. Inhibition of collagen cross-linking may represent an alternative method to the use of injectable 5-fluorouracil to maintain patency of filtration blebs.
