To investigate the characteristics of horizontal rectus muscle insertion sites in patients with infantile esotropia (IE) and acute acquired concomitant esotropia (AACE).
The medical records of 166 IE patients and 261 AACE patients who underwent horizontal rectus muscle surgeries were reviewed retrospectively, including age at surgery, spherical equivalent (SE), and angle of esodeviation at near and distance. The limbus-insertion distances (LID) and widths of the medial rectus (MR) and lateral rectus (LR) muscles were measured intraoperatively using a caliper. The insertion parameters and clinical features were compared between different ages and types of esotropia, and a correlation analysis was performed between these variables.
In IE patients under 12 years old, the MR LID was positively correlated with age, whereas the LR LID was negatively correlated with the angle of esodeviation at distance. In IE patients over 12 years old, the LR width was negatively correlated with the angle of esodeviation at near. In AACE patients, the MR LID was negatively correlated with the angle of esodeviation at distance, whereas the LR width was negatively correlated with the SE.
The LID and width of the horizontal rectus muscle insertions were not significantly different in age-matched patients with IE and AACE. In IE patients, the LR insertion parameters were correlated with the angle of esodeviation, but in AACE patients, the MR LID was correlated with the angle of esodeviation. The clinical significance of these findings still needs to be investigated further.
研究婴儿型内斜视（IE）和急性后天性共同性内斜视（AACE）患者水平直肌附着点的特征。
回顾性分析166例接受水平直肌手术的IE患者和261例AACE患者的病历，包括手术年龄、等效球镜度（SE）以及近距和远距离内斜视角。术中使用卡尺测量角膜缘至内直肌（MR）和外直肌（LR）附着点的距离（LID）以及肌肉宽度。比较不同年龄和类型内斜视患者的附着点参数和临床特征，并对这些变量进行相关性分析。
12岁以下的IE患者中，MR的LID与年龄呈正相关，而LR的LID与远距离内斜视角呈负相关。12岁以上的IE患者中，LR宽度与近距离内斜视角呈负相关。在AACE患者中，MR的LID与远距离内斜视角呈负相关，而LR宽度与SE呈负相关。
年龄匹配的IE和AACE患者水平直肌附着点的LID和宽度无显著差异。在IE患者中，LR附着点参数与内斜视角相关，但在AACE患者中，MR的LID与内斜视角相关。这些发现的临床意义仍需进一步研究。
