“…During the follow‐up of these patients, the success rate of the operation diminished because the material shrank by about one‐third. Blohme et al (1999) reported good results with bank scleral crafts and, in the same year, Harrer et al (1999) published a report on the elongation of the muscle tendon in nine patients for correction of VI nerve palsy, Duane syndrome and strabismus fixus, using polytetrafluoroethylene (Goretex ® ), which was already well known in cardiac and plastic surgery.…”

“…Contrary to the practice of others (Harrer et al 1999), we used Vicryl 6.0 for end‐to‐end fixation of the Goretex ® strip to the rectus muscle as we knew from histological examination that the material would be enclosed by a layer of connective tissue, undistinguishable from normal tendon within its sheath, and that the extraocular muscle would grow into the structure of the polytetrafluoroethylene patch.…”

ABSTRACT.Purpose: Repeated strabismus surgery as well as eye muscle fibrosis in various forms of strabismus, can be followed by restriction of the motility of the eye. Tendon elongation may be necessary if further improvement of the deviation and duction of the eye muscle is to be achieved. We used polytetrafluoroethylene (Goretex Ò ) and looked at its user comfort, compatibility and dose-rate relationship. Method: Three patients with consecutive exotropia after repeated operations for congenital esotropia, two patients with VI nerve palsy and residual head turn after combined convergence operation and one child with congenital fibrosis syndrome underwent muscle tendon elongation with Goretex Ò (7-15 mm) of either the medial or the lateral rectus muscle, which had already been resected and/or recessed in former surgeries. Forced duction under general anaesthesia was restricted in all patients. Results: The correction of the deviation in primary position (deviation at distance + 3 to -4 and at near -1 to -8 ) and in side gaze was satisfactory and motility was clearly improved. There were no postoperative complications (infection, shrinkage, scarring) and the postoperative results in terms of the angle of deviation and the improvement in motility remained stable for 1-6 years. Conclusion: Polytetrafluoroethylene (Goretex Ò ) is a good material with which to resolve complicated cases of strabismus in which muscle tendon elongation for bulbus restriction is necessary.

“…As an alternative for hang-back sutures, muscle elongation with allograft material has been used (9-12). In addition, artificial materials such as Gore-Tex® have been applied (13, 14). Recently, the use of xenograft material in the form of bovine pericardium has been reported (15-19).…”

Background: Extraocular muscles may be recessed using implants as spacer material. Silicone retinal band is an example of a spacer used to elongate the superior oblique (SO) tendon in Brown’s syndrome and SO overaction; however, complications such as extrusion, scarring and restriction due to the implant have been reported. The purpose of our study was to evaluate and compare fibroblastic and inflammatory reactions to different alloplast materials in a rabbit model. Method: Twenty-three rabbit eyes underwent superior rectus (SR) expander surgery, and 9 eyes SR recession surgery. SR expander surgery was performed using either silicone retinal band (240 style; 6 eyes), polytetrafluoroethylene (Gore-Tex; 10 eyes) or porous polyethylene (Medpor; 7 eyes). Twenty eyes were enucleated at 4 weeks and 12 eyes at 8 weeks and examined by light microscopy. The expression of basic fibroblast growth factor (bFGF) was evaluated by immunohistochemical analysis. Results: All alloplast materials induced more inflammatory response compared to control eyes (p < 0.05). Medpor induced a markedly stronger inflammatory response than silicone and Gore-Tex (p < 0.05). Gore-Tex and silicone induced similar inflammatory responses. Gore-Tex implants yielded a slightly higher bFGF expression than silicone or Medpor implants (p = 0.07). Conclusion: Polytetrafluoroethylene (Gore-Tex) was found to be similar to silicone in its biocompatibility when used as spacer material in extraocular muscle tendon expander surgery. The high bFGF expression observed in Gore-Tex-implanted eyes suggests porous polymers may promote tissue ingrowth into the implant.
