摘要

目的：本研究详细介绍了手术治疗原发性间歇性外斜视（X(T)）或v型外斜视（VXT）患者的临床特征，这些患者在手术中发现有下移位的外直肌（LR）。方法：回顾性分析2013年至2023年的医疗记录，包括双侧侧直肌衰退（blrrecc）进行X(T)和blrrecc联合双侧下斜肌切除术，或不进行上斜肌腱转位进行VXT的患者。结果：在211例患者中，138例接受了blrec，显示42例（30%）有下移位的LR肌肉插入，特别是在VXT病例中更常见（58%对14%）。此外，44%的VXT患者表现出异常的下斜肌（IO）解剖结构，通常伴有下LR肌腱移位。结论：这些发现突出了VXT中LR异常的患病率。了解这些解剖变异可能有助于手术计划。

Anomalies of lateral rectus muscle and inferior oblique muscle in exotropia.

Objective: This study details the clinical characteristics of patients undergoing surgery for basic intermittent exotropia (X(T)) or V-pattern exotropia (VXT) who are found to have inferiorly displaced lateral rectus (LR) muscles during surgery.

Methods: A retrospective review of medical records from 2013 to 2023 included patients who underwent bilateral lateral rectus recession (BLRrec) for X(T) and BLRrec combined with bilateral inferior oblique myectomy, with or without upward LR tendon transposition for VXT.

Results: Among 211 patients, 138 underwent BLRrec, revealing that 42 (30%) had inferiorly displaced LR muscle insertions, notably more common in VXT cases (58% vs 14%). Additionally, 44% of VXT patients exhibited abnormal inferior oblique (IO) muscle anatomy, often alongside inferior LR tendon displacement.

Conclusions: These findings highlight the prevalence of LR abnormalities in VXT. Awareness of these anatomical variations may be helpful to surgical planning.
