Resumen
Purpose: An experimental study to evaluate the behavior of polytetrafluoroethylene (Gore-Tex®) compared with human sclera, in scleral perforations induced in rabbits eyes was performed. Methods: Twenty-two eyes of rabbits were submitted to scleral perforation followed by Gore-Tex® graft in the left eye and human sclera graft in the right eye respectively. During one month the postoperative evolution was analyzed every day: intensity of hyperemia, presence of infection, secretion, rejection and tonicity of the eyes. Results: No cases of secretion, infection or rejection were observed. The histological sections showed fibrosis in the eyes with Gore-Tex®, good adhesion and epithelization. Conclusion: The Gore-Tex® showed to be a plausible material to be used as graft in scleral defects with some advantages such as easy obtention, good handling and durability. 64 6 563 567 Koenig, S.B., Kaufman, H.E., The treatment of necrotizing scleritis with an autogenous periosteal graft (1983) Ophthalmic Surg, 14, pp. 1029-1032 Blum Jr., F.G., Salamoun, S.G., Scleromalacia perforans: A useful surgical modification in fascia lata or scleral grafting (1963) Arch Ophthalmol, 69, p. 287 Merz, E.H., Scleral reinforcement with aortic tissue (1964) Am J Ophthalmol, 57, pp. 66-70 Huang, W.J., Hu, F.R., Chang, S., Clinicopathologic study of gore tex path grafting corneoscleral surgery (1994) Cornea, 13, pp. 82-86 Mauriello Jr., J.A., Pokorny, K., Use of split-tickness dermal grafts to repair corneal and scleral defets-a study of 10 patients (1993) Br J Ophtalmol, 377, pp. 327-331 Nishiwaki-Dantas, M.C., Abbott, R.L., Dantas, P.E.C., Use of corneal patch graft repair scleral defect secondary to pterygium excision and topical mitomycin-C therapy (1995) Arq Bras Oftalmol, 58, pp. 170-173 Koenig, S.B., Sanitato, J.J., Kaufman, H.E., Long-term follow-up study of scleroplasty using autogenous periosteum (1990) Cornea, 9, pp. 139-143 Legeais, J.M., Renard, G., D'Hermies, F., Rossi, C., Pouliquen, Y., Surgical management of corneal perforation with explanded polytetrafluorethylene (Gore Tex) (1991) Ophthalmic Surg, 22, pp. 213-217 Bick, M.W., Surgical treatment of scleromalacia perforans (1959) Arch Ophthalmol, 61, pp. 907-917 Mauriello Jr., J.A., Fiore, P.M., Pokorny, K.S., Cinotti, D.J., Use of split-tickness dermal grafts in the surgical treatment of corneal and scleral defects (1988) Am J Ophthalmol, 105, pp. 244-247 Nishiwaki-Dantas, M.C., Abbott, R.L., Dantas, P.E.C., Reparação de defeito escleral ou corneo-escleral com enxerto corneano (1995) Arq Bras Oftalmol, 58, pp. 295-298 Florian, A., Cohn, L.H., Dammin, G.J., Collins, J.J., Small vessel replacement with Gore-Tex (expanded polytetrafluoroethylene) (1976) Arch Surg, 111, pp. 267-270 Kenyon, K.R., Wagoner, M.D., Hettinger, M.T., Conjunctival autograft transplantation for advanced and recurrent pterygium (1985) Ophthalmology, 92, pp. 1461-1470 Obear, M.F., Winter, F.C., (1964) Technique of Overlay Scleral Homograft Arch Ophthalmol, 71, pp. 837-838 Raizman, M.B., De La Dsainz Maza, M., Foster, C.S., Tectonic keratoplasty for peripheral ulcerative keratitis (1991) Cornea, 10, pp. 312-316 Breslin, C.W., Katz, J.I., Kaufman, H.E., Surgical treatment of necrotizing scleritis (1977) Arch Ophthalmol, 95, pp. 2038-2040 Tawakol, M.E., Peyman, G., Lui, K.R., Kaufman, H.E., Gore-Tex soft tissue bands as scleral explants in rabbits a preliminary histologic study (1989) Ophtthalmic Surg, 20, pp. 199-201 Whitmore, W.G., Harrison, W., Curtis, B.J., Scleral reinforcement in rabbits using synthetic graft materials (1990) Ophthalmic Surg, 21, pp. 327-330
