| Abstract |
|
The histopathological changes were observed to evaluate the effect of single intraopferative application of mitomycin C soaked Cottonoid on wound healing process after strabismus surgery. A 3mm recession of the superior rectus muscle was performed after application of 0.5mg/ml mitomycin C soaked Cottonoid for 5 minutes in one eye of 15 rabbits(30 eyes) and was copiously irrigated with normal saline. The same procedure was done in the contralateral eye as a control using normal saline. The less amount of inflammatory cellular infiltration and the less granulomatous reaction to suture material were observed in mitomycin C treated eyes. The proliferation of fibroblast was considerably inhibited in mitomycin C-treated group. The postoperative adhesion, the fibrosis of extrocular muscle and the depositon of collagen fibers were also decreased in mitomycin C-treated group. Gross complications was not present in rabbit during 3 months of experiment. No pathologic sign of undesirable side effects was noted. In conclusion, the single intraoperative application of mitomycin C soaked Cottonoid could decrease the postoperative adhesion and extraocular muscle fibrosis through its inhibitory effects on the inflammatory reaction and fibroblast proliferation in strabismus surgery without any complications which were reported in subconjunctival injection of mitomycin C. Further studies investigating the optimal concentration, application method and time of mitomycin C soaked Cottonoid and its promising potential for use in humans are needed. |
