: To evaluate the efficacy of polytetrafluoroethylene/polylactide-co-glycolide (PTFE/PLGA) laminate containing sustained-release thalidomide for delayed adjustable strabismus surgery. : This is a prospective, masked-observer, controlled study using 50 eyes of 25 rabbits. After superior rectus muscle (SRM) recession, a PTFE/PLGA laminate containing thalidomide (group PT, 20 eyes), PTFE/PLGA laminate alone (group P, 20 eyes), or no barrier (group C, 10 eyes) were applied around the SRM. Delayed adjustment was performed at postoperative 3 or 5 weeks. Adjustability, adjustment lengths, adjustment forces, and degrees of adhesion were evaluated. : Both groups PT and P showed significantly better adjustability compared to group C at both 3 weeks (100%, 80%, and 0%, respectively) and 5 weeks (100%, 90%, and 0%, respectively). Between groups PT and P, adjustability, adjustment lengths, and forces were not significantly different at 3 and 5 weeks. Group PT showed a significantly lower grade of adhesion between SRM and sclera (SRM/S) compared to group C at both 3 weeks ( = 0.007) and 5 weeks ( = 0.001, respectively). Group P showed no significant difference in adhesion between SRM/S compared to group C at 3 weeks (= 0.302) but had a lower grade of adhesion after 5 weeks ( = 0.007). There was no significant difference between groups PT and P at 3 weeks (= 0.143) and 5 weeks (= 0.716). : PTFE/PLGA laminate containing sustained-release thalidomide was effective in reducing adhesion and allowed delayed adjustment in all eyes. However, PTFE/PLGA laminate alone was also equally effective in reducing adhesion compared to controls.
评价含持续释放沙利度胺的聚四氟乙烯/聚乳酸-羟基乙酸共聚物(PTFE/PLGA)层压物用于延迟可调节斜视手术的疗效。
这是一项前瞻性、盲法观察者、对照研究,共纳入 25 只兔子的 50 只眼。在进行上直肌(SRM)后退术后,将含沙利度胺的 PTFE/PLGA 层压物(PT 组,20 只眼)、单纯 PTFE/PLGA 层压物(P 组,20 只眼)或不使用任何屏障(C 组,10 只眼)应用于 SRM 周围。在术后 3 或 5 周时进行延迟调整。评估调节性、调节长度、调节力和粘连程度。
PT 组和 P 组在术后 3 周(分别为 100%、80%和 0%)和 5 周(分别为 100%、90%和 0%)时的调节性明显优于 C 组。在 3 周和 5 周时,PT 组和 P 组之间的调节性、调节长度和力无显著差异。PT 组在术后 3 周(=0.007)和 5 周(=0.001)时,SRM 与巩膜(SRM/S)之间的粘连程度明显低于 C 组(=0.007)。P 组在术后 3 周时与 C 组相比,SRM/S 的粘连程度无显著差异(=0.302),但 5 周后粘连程度较低(=0.007)。PT 组和 P 组在 3 周(=0.143)和 5 周(=0.716)时无显著差异。
含持续释放沙利度胺的 PTFE/PLGA 层压物可有效减少粘连,并使所有眼睛均能进行延迟调整。然而,与对照组相比,单纯的 PTFE/PLGA 层压物在减少粘连方面也同样有效。
