Abstract:
To evaluate the possibility of Dacron patch for artificial sclera. Dacron(polyethylene terephthalate) which is readily available, biocompatable, safe, and inert synthetic material was implanted in the area of full-thickness scleral defect in rabbits. The histopathologic examinations showed that fibrovascular tissue invested into all interstices of Dacron filaments and fibroconnective tissue encapsulation around Dacron patch had strong connection with collagen fibers of recipient sclera at 4 weeks after graft There were no adverse reactions such as retinal detachment and fibrous proliferation into the vitreous cavity except mild inflammatory response of surrounding tissue at the early postoperative stage. As a result, Dacron graft showed successful firm adhesion to the recipient sclera without serious complications. Thus, We think that Dacron could possibly be used, instead of donor sclera, as artificial scleral graft material for the surgical treatment of perforating scleral diseases.
