眼科影像检查在斜视诊疗中的应用

Application of ophthalmic imaging techniques in strabismus

近年来,医学影像学检查手段多样化发展,在斜视的诊断和处理方面有很多应用。在斜视手术前,超声生物显微镜、前节相干光断层扫描可对眼外肌进行定位,对复杂斜视患者尤其需要再次手术的患者进行术前评估。并且,术前借助彩色超声多普勒成像、虹膜血管造影技术以及相干光断层扫描血管成像技术评估眼前节的供血情况,合理设计手术,可有效避免斜视手术后眼前节缺血的发生。此外,人工智能采用眼球跟踪系统以及图像识别技术对斜视进行筛查和评估,有助于早发现早诊疗。(国际眼科纵览,2022,46:139-143)

In recent years,with the diversified development of medical imaging techniques,there are many applications in the diagnosis and treatment of strabismus.Ultrasound biomicroscopy(UBM),anterior segment optical coherence tomography(AS-OCT)could accurately locate the insertions of extraocular muscle before surgery,and evaluate the patients with complex strabismus,especially those requiring reoperation.Due to prevent vision-threatening complications after strabismus surgery,color Doppler imaging(CDI),iris angiography,and optical coherence tomography angiography(OCTA)were performed preoperatively,which could be useful tools in the evaluation of patients undergoing strabismus surgery to determine whether a patient is at risk to develop anterior segment ischemia.In addition,eye-tracking data and convolutional neural network can be used to identify strabismus effectively and enable patients to receive treatment timely.(Int Rev Ophthalmol,2022,46:139-143)
