To describe the long-term results of Anderson procedure, which includes recession of the two extraocular yoke muscles responsible for eccentric eye position and abnormal head posture (AHP) in patients with infantile nystagmus.
Retrospective data collection of patients who underwent an Anderson procedure at a single medical center by one surgeon from 2008 to 2016. The main outcome measure was the elimination of AHP following surgery.
Twenty-seven patients (18 males, 9 females) underwent an Anderson procedure during the study period. The average age at surgery was 8.6 ± 7.7 years and mean follow-up was 3.5 ± 2.4 years (range, 6 months-9 years). Before surgery all patients had AHP (17 left and 10 right head turns) greater than 25° (mean 40.1 ± 6.7°) that decreased significantly following surgery (mean 7.2 ± 7.6°, P < 0.001). Surgery resulted in complete elimination of AHP in 14 (52%) patients. In 10 (37%) patients the residual head turn was 15° or lower, and in only 3 (8%) the post-operative AHP was 25° or larger, requiring further surgery. It is important to note that none of the patients developed strabismus or duction limitation following surgery.
Long-term results following the Anderson procedure show a stable decrease in AHP in patients with infantile nystagmus, often resulting in complete restoration of normal head posture. Involved risks of strabismus and limitation of ocular motility appear to be low.
描述 Anderson 手术的长期结果，该手术包括退缩负责偏心眼位和异常头位（AHP）的两条眼外轭肌，用于治疗婴儿性眼球震颤患者。
回顾性收集 2008 年至 2016 年期间，一位外科医生在一家医疗中心为 27 名患者进行 Anderson 手术的资料。主要的观察指标是手术后 AHP 的消除情况。
在研究期间，有 27 名患者（18 名男性，9 名女性）接受了 Anderson 手术。手术时的平均年龄为 8.6±7.7 岁，平均随访时间为 3.5±2.4 年（6 个月至 9 年）。术前所有患者的 AHP（17 例左侧和 10 例右侧头部转动）大于 25°（平均 40.1±6.7°），手术后明显降低（平均 7.2±7.6°，P<0.001）。手术导致 14 名（52%）患者完全消除了 AHP。在 10 名（37%）患者中，残余的头部转动为 15°或更低，仅 3 名（8%）患者手术后 AHP 为 25°或更大，需要进一步手术。需要注意的是，手术后没有患者出现斜视或运动受限。
Anderson 手术后的长期结果显示，婴儿性眼球震颤患者的 AHP 稳定下降，通常导致正常头部姿势的完全恢复。涉及的斜视和眼球运动受限的风险似乎较低。
