To discuss the novel swept-source anterior segment optical coherence tomography (SS-ASOCT)-guided surgical approach in slipped medial rectus muscles.
Prospectively (between February 2020 and July 2022), six patients with a clinical suspicion of slipped medial rectus muscle were recruited. After complete ophthalmic and orthoptic evaluation, the missing medial rectus muscle is screened using Anterior Segment Optical Coherence Tomography (ASOCT). In presence of a traceable muscle, its morphology, depth, and distance from a fixed anatomical landmarks were noted; in its absence, the status of other recti was noted. Intraoperatively, the features were confirmed and the intended intervention was performed.
The mean age of six patients was 25.66 ± 9.72 years, two with surgical trauma and four with penetrating trauma (66.66%). In five patients, the ASOCT traced the slipped medial rectus muscle successfully (83.33%); intraoperatively, the same was confirmed (within 1-2 millimeters) with favorable outcomes. ASOCT made a significant contribution in all subjects by reducing the number of interventions and muscle surgeries.
In eyes with slipped medial rectus muscle, especially those which are within a finite distance from the angle can be traced using ASOCT. This approach impacts the outcomes in many ways.
探讨新型扫频源眼前节光学相干断层扫描（SS-ASOCT）引导下内直肌滑脱的手术方法。
前瞻性地（2020 年 2 月至 2022 年 7 月），招募了 6 例临床怀疑内直肌滑脱的患者。在完成全面的眼科和斜视检查后，使用眼前节光学相干断层扫描（ASOCT）筛查缺失的内直肌。在存在可追踪肌肉的情况下，记录其形态、深度以及与固定解剖标志的距离；在不存在可追踪肌肉的情况下，记录其他直肌的状态。术中确认特征并进行预期的干预。
6 例患者的平均年龄为 25.66 ± 9.72 岁，其中 2 例为手术创伤，4 例为穿透性创伤（66.66%）。在 5 例患者中，ASOCT 成功追踪到内直肌滑脱（83.33%）；术中同样确认（在 1-2 毫米范围内），结果良好。ASOCT 通过减少干预和肌肉手术的次数，对所有患者都做出了重要贡献。
在存在内直肌滑脱的眼中，尤其是那些距离角度有限的眼中，可以使用 ASOCT 进行追踪。这种方法在多个方面影响着治疗结果。
