目的：反复的斜视手术以及各种形式的斜视中的眼肌纤维化，可以随后限制眼睛的运动。如果要进一步改善眼肌的偏斜和收缩，肌腱延长可能是必要的。我们用聚四氟乙烯（Goretex（R））并观察其用户舒适度、相容性和剂量率关系。3例先天性内斜视多次手术后继发外斜视，2名VI神经麻痹和联合会聚手术后残留头转向的患者和1名先天性纤维化综合征的儿童接受了Goretex（R）（7-15 mm）肌腱延长术在以前的手术中已经切除和/或凹陷的内直肌或外直肌。结果：术后主位偏斜（远位偏斜+3 ° ~-4 °，近位偏斜-1 ° ~-8 °）和侧视偏斜矫正满意，运动功能明显改善。术后无感染、收缩、瘢痕形成等并发症，斜视角度及眼球运动功能改善情况1-6年保持稳定。结论：聚乙烯（Goretex（R））是一种较好的材料，可用于解决因眼球限制而需延长肌腱的复杂斜视病例。
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(R)) 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(R) (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 degrees to -4 degrees and at near -1 degrees to -8 degrees) 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(R)) is a good material with which to resolve complicated cases of strabismus in which muscle tendon elongation for bulbus restriction is necessary.
