摘要

目的:据报道,斜视手术患者中有20-40%需要再手术。本研究探讨了基于眼外肌插入的术前成像的再手术结果,以及前段光学相干断层扫描(ASOCT)是否有价值。方法:在昌迪加尔高级眼科中心招募有/无手术记录的斜视患者进行再手术。所有患者均在扫源前段光学相干断层扫描上进行了全面的临床检查和眼外肌插入成像。用ASOCT测量肌肉插入的准确性与术中卡尺读数进行比较。结果:47块肌肉(28例)在ASOCT上显像,术中再次手术时得到确认。患者平均年龄21.6±5.6岁。在观察影像学表现后,11名患者(39.2%)改变了对手术部位的决定。ASOCT测量肌肉止点±1 mm的准确度为78.7%(38/47块肌肉)。ASOCT可以提供额外的信息,例如三名患者的肌肉滑动和拉伸疤痕。结论:在斜视再手术中,影像学检查有助于获得高准确度的成功结果。它在再手术的手术计划中起关键作用(约40%)。

Outcomes of OCT imaging-based reoperations in strabismus.

Purpose: Reoperations in strabismus are reportedly needed in 20-40% of cases undergoing surgery. The present study investigated the outcomes of reoperations based on preoperative imaging of extraocular muscle insertions, and whether the Anterior Segment Optical Coherence Tomography (ASOCT) was of value.

Methods: Patients with strabismus requiring reoperation with/without previous surgical records at the Advanced Eye Centre, PGIMER, Chandigarh were recruited. All patients underwent a thorough clinical examination and imaging of extraocular muscle insertions on the Swept Source Anterior Segment Optical Coherence Tomography. The accuracy of measuring muscle insertions with the ASOCT was compared with intraoperative caliper readings.

Results: Forty-seven muscles (28 patients) were imaged on ASOCT with confirmation intraoperatively during re-operation. The mean age of the patients was 21.6 ± 5.6 years. After looking at the imaging findings, the decision of which muscle to operate on changed in eleven patients (39.2%). The accuracy of ASOCT to measure muscle insertion ± 1 mm was seen in 78.7% (38/47 muscles). The ASOCT could give additional information, such as a slipped muscle and stretched scar in three patients.

Conclusions: Imaging can be beneficial in achieving successful results in strabismus reoperations with high accuracy. It can be pivotal in surgical planning in reoperations (~ 40%).
