This study aimed to compare the preoperative clinical features of patients with sensory esotropia (ET) and sensory exotropia (XT).
In a retrospective study, the medical records of 13,252 patients who underwent strabismus surgery were reviewed at the Farabi Eye Hospital, Iran, from 2012 to March 2022. There were 1017 patients with sensory horizontal strabismus whose, in their worse eye, had corrected distance visual acuity (CDVA) equal to or <20/160 tested with the Snellen chart.
The mean age of patients was 29.0 ± 12.4 years [574 (56.4%) males and 443 (43.6%) females]. Sensory XT and ET were observed in 717 (70.5%) and 300 (29.5%) patients, respectively (P<.001). The mean CDVA in the strabismic and non-strabismic eyes was 1.40 ± 0.75 and 0.05 ± 0.13, respectively (P<.001). Also, the CDVA in the strabismic eyes was significantly worse in the patients with sensory XT than in the patients with sensory ET (P<.001). Sphere and spherical equivalent (SE) components were more hyperopic in both eyes of patients with sensory ET than sensory XT (P<.001). In sensory ET group, the mean horizontal deviation at far and near was significantly higher than the sensory XT group (both P<.001). The prevalence of moderate and severe amblyopia among all patients with sensory strabismus was 274 (26.9%) and 727 (71.5%), respectively (P<.001). There were 398 (39.1%) patients who needed more than one surgery.
The frequency of sensory XT was about 2.5 times more than the sensory ET. Most patients with sensory ET were operated at a younger age, had better CDVA, more hyperopic spherical and SE, and higher angle of deviation compared with patients with sensory XT. The chance of reoperation in patients with sensory strabismus was about 40%.
本研究旨在比较感觉性内斜视（ET）和感觉性外斜视（XT）患者的术前临床特征。
在一项回顾性研究中，对 2012 年至 2022 年 3 月在伊朗法里比眼科医院接受斜视手术的 13252 名患者的病历进行了回顾。1017 例感觉性水平斜视患者，在其较差眼，用 Snellen 图表测试的矫正远距视力（CDVA）等于或<20/160。
患者的平均年龄为 29.0±12.4 岁[574 名（56.4%）男性和 443 名（43.6%）女性]。分别观察到 717 例（70.5%）和 300 例（29.5%）患者存在感觉性 XT 和 ET（P<.001）。斜视眼和非斜视眼的平均 CDVA 分别为 1.40±0.75 和 0.05±0.13（P<.001）。此外，感觉性 XT 患者斜视眼的 CDVA 明显差于感觉性 ET 患者（P<.001）。在感觉性 ET 组中，双眼的球镜和等效球镜（SE）成分均较感觉性 XT 组更为远视（均 P<.001）。在感觉性 ET 组中，远、近距水平偏斜的平均水平明显高于感觉性 XT 组（均 P<.001）。所有感觉性斜视患者中，中度和重度弱视的患病率分别为 274 例（26.9%）和 727 例（71.5%）（P<.001）。需要进行超过一次手术的患者有 398 例（39.1%）。
感觉性 XT 的频率约为感觉性 ET 的 2.5 倍。与感觉性 XT 患者相比，大多数感觉性 ET 患者年龄较小，CDVA 较好，球镜和 SE 更远视，斜视角度更高。感觉性斜视患者再次手术的几率约为 40%。
