Fluorouracil Filtering Surgery Study (FFSS)
Study Overview
Detailed Description
Filtering surgery adequately lowers intraocular pressure in most glaucoma patients. However, the prognosis is less favorable for aphakic patients with glaucoma or glaucoma in phakic eyes following unsuccessful filtering operations. Failure of filtering surgery is usually attributed to the proliferation of fibroblasts at the filtering site. The use of 5-FU, an antimetabolite, has been shown to inhibit the proliferation of fibroblasts in tissue culture, and in preliminary studies it has increased the success of filtering surgery in a nonhuman primate model.
The Fluorouracil Filtering Surgery Study (FFSS) was a randomized, controlled clinical trial comparing the success rate of standard glaucoma filtering surgery to the success rate of standard surgery with adjunctive 5-FU treatment.
Another element of this study was to evaluate the frequency and severity of possible adverse effects related to 5-FU injections. Detailed preoperative and postoperative examinations of the cornea, lens, and retina were performed. Systemic toxicity was assessed by preoperative and postoperative hematologic studies.
After the investigators performed the filtering surgery and determined that the new outlet channel was working, patients were randomized to receive either 5-FU injections or standard postsurgical care without 5-FU. The patients treated with 5-FU received subconjunctival injections of 5 mg of 5-FU twice daily on postoperative days 1 through 7 and once daily on postoperative days 8 through 14. There were 213 patients recruited into the study, 162 with previous cataract extraction and 51 with previous filtering surgery.
All patients were examined at 1 month, 3 months, 6 months, 1 year, 18 months, and 2 years postoperatively and at yearly intervals thereafter until 5 years postoperatively. Possible concomitant risks of 5-FU treatment, such as toxic effects to the cornea, lens, or retina, were monitored.
