Abstract

A study on the pathologic findings after recession and resection of extraocular muscles in rabbits was performed. Fibrosis of extraocular muscles increased with time, which showed no difference between recessed and resected muscles. Inflammation and foreign body reaction decreased with time, which showed no difference between recessed and resected muscles. Adhesions of extraocular muscles to the sclera were observed from 1 month after operation. The resected muscles showed milder adhesion to the sclera than recessed one. The operated extraoculr muscles showed atrophies at 1 month, which showed no difference between recessed and resected muscles. According to our results, when reoperation is needed, fibrosis of extraocular muscles after recession and resection should be considered in making decision of recession and resection amount of muscles.
