The aim of this study is to present the results of surgery in intermittent divergent strabismus with adjustable sutures, and to compare them to the results of conventional technique.
The study group consisted of 25 patients operated in our department because of intermittent divergent squint with adjustable sutures--group I and with conventional technique--group II. The age range was from 17 to 46 years in group I and from 14 to 37 years in group II. The results were compared in both of groups. We assessed the possibility of postoperative eye alignment in hypercorrection from +4D to +6D (recession/resection) and from +6D to +8D (bilateral recession). Number of patients without a precise effect was calculated. The eye alignment was changed in the immediate postoperative period. Quantity of postoperative drift in both groups was estimated.
The intended eye alignment from +4D to +6D was achieved in 29% and from +6D to +8D in 31% of patients with adjustable sutures (group I). The eye alignment in the group II operated with conventional technique was 21% from +4D to +6D and 19% from +6D to +8D.
The use of adjustable sutures in the intermittent divergent strabismus resulted in more correct alignment and avoidance of diplopia. This method enables also to limit or enlarge extent of the surgery and leads to significant decrease of the need for surgical interventions.
本研究旨在呈现采用可调节缝线治疗间歇性外斜视的手术结果，并将其与传统技术的结果进行比较。
研究组包括25例在我院接受手术的患者，其中一组（I组）采用可调节缝线治疗间歇性外斜视，另一组（II组）采用传统技术。I组患者年龄范围为17至46岁，II组为14至37岁。对两组结果进行比较。我们评估了术后眼位矫正过度（从+4棱镜度至+6棱镜度（后徙/缩短）以及从+6棱镜度至+8棱镜度（双侧后徙））的可能性。计算未获得精确效果的患者数量。术后即刻改变眼位。估计两组术后漂移量。
采用可调节缝线的患者（I组）中，29%实现了从+4棱镜度至+6棱镜度的预期眼位矫正，31%实现了从+6棱镜度至+8棱镜度的矫正。采用传统技术的II组患者中，从+4棱镜度至+6棱镜度的眼位矫正为21%，从+6棱镜度至+8棱镜度为19%。
在间歇性外斜视中使用可调节缝线可实现更准确的眼位矫正并避免复视。该方法还能够限制或扩大手术范围，并显著减少手术干预的需求。
