Introduction: To determine whether 5-fluorouracil is effective in reducing scarring after strabismus surgery we used rectus muscle surgery in experimental animals to compare a single intraoperative dose of 5-fluorouracil with mitomycin C and to compare results in similarly treated controls not receiving these antimetabolites. Methods: Muscle resections were performed on eight rabbits (16 eyes). Four eyes had 5-fluorouracil (50 mg/ml), and four eyes received mitomycin C (0.2 mg/ml), each of which was applied during surgery on an ophthalmic sponge for 5 minutes. Eight eyes served as controls. Six weeks after surgery conjunctival vascularity, muscle length-tension curves, muscle disinsertion force, and the histologic degree of scarring were assessed. Results: The mitomycin C-treated eyes clearly had more conjunctival avascularity and a lower disinsertion force. Both treated groups had flatter length-tension curves and less scarring on histologic examination than the control eyes. Conclusions: Antifibroproliferative therapy with intraoperative sponge 5-fluorouracil appears as effective as, and is possibly safer than, mitomycin C. It may be a useful adjunct in recurrent strabismus surgery or in other situations where a risk of excessive postoperative scarring exists.
