To investigate the long-term outcomes of intermittent exotropia surgery for children less than 4 years of age.
Consecutive patients who underwent surgery for intermittent exotropia and had follow-up durations longer than 2 years were recruited. The patients were classified according to age at surgery-the patients of group 1 had undergone surgery before 4 years of age and those of group 2 at or after 4 years of age. Motor success was defined by exodeviation < 10 prism diopters (PD) and esodeviation < 5 PD at distance at 2 years postoperatively. Stereoacuity was considered as success at a value ≤ 60 arc seconds. The motor and sensory success rates as well as the surgical complications were compared.
Of the 73 patients, 36 were allocated to group 1 and 37 to group 2. At 2 years after surgery, 13 of the 36 (36.1%) patients in group 1 and 12 of the 37 (32.4%) in group 2 had achieved successful alignment; 32 (88.9%) patients in group 1 and 35 (94.6%) in group 2 achieved normal stereoacuity. No significant differences in the motor or sensory success rates were observed between the two groups (p = 0.46 and 0.32, respectively).
The surgical success rates for intermittent exotropia were comparable between the patients operated upon before 4 years of age and those operated upon after 4 years of age. The incidence of postsurgical complications was low and not significantly different between the two study groups.
探讨4岁以下儿童间歇性外斜视手术的长期疗效。
招募接受间歇性外斜视手术且随访时间超过2年的连续患者。根据手术时的年龄对患者进行分类——第1组患者在4岁前接受手术，第2组患者在4岁及以后接受手术。术后2年时，远距离外斜视度<10棱镜度（PD）且内斜视度<5 PD定义为运动成功。立体视锐度≤60角秒视为成功。比较运动和感觉成功率以及手术并发症。
73例患者中，36例被分配到第1组，37例被分配到第2组。术后2年时，第1组36例患者中有13例（36.1%）实现了成功的眼位矫正；第2组中37例患者中有12例（32.4%）实现了成功的眼位矫正。第1组32例（88.9%）患者和第2组35例（94.6%）患者实现了正常的立体视锐度。两组之间在运动或感觉成功率方面未观察到显著差异（p值分别为0.46和0.32）。
4岁前接受手术的间歇性外斜视患者与4岁后接受手术的患者的手术成功率相当。两个研究组术后并发症的发生率都较低且无显著差异。
