Intraoperative portable handheld and microscope-integrated OCT enhance the pediatric vitreoretinal surgeon's diagnostic abilities during examination under anesthesia and surgery, particularly in children who are challenging to examine preoperatively due to young age or ocular trauma. Improved OCT-guided visualization of vitreoretinal anatomic relationships has the potential to improve surgical safety and efficiency. In retinopathy of prematurity and other pediatric retinal vascular conditions, intraoperative OCT can be critical for distinguishing between retinoschisis and retinal detachment and highlighting abnormalities of the vitreoretinal interface that may contribute to development of tractional retinal detachments. During retinal detachment repair, intraoperative OCT aids identification of subtle retinal breaks, residual subretinal fluid, retained perfluorocarbon, preretinal membranes, and residual hyaloid, among other findings. In macular surgery, intraoperative OCT has demonstrated value in confirming completion or lack thereof of epiretinal and internal limiting membrane peeling and differentiating between lamellar and full-thickness macular holes. OCT-guided subretinal bleb formation and genetic vector delivery are critical to ensuring accurate localization of subretinal gene delivery for inherited retinal degenerations. Research on development of OCT-compatible surgical instruments, real-time three-dimensional volumetric OCT imaging, and integration with intraoperative OCT angiography are anticipated to further increase the utility of intraoperative OCT in pediatric vitreoretinal surgical decision-making.
术中便携式手持和显微镜集成式光学相干断层扫描(OCT)可增强小儿玻璃体视网膜外科医生在麻醉检查和手术过程中的诊断能力,尤其是对于那些因年龄小或眼外伤而术前检查具有挑战性的儿童。OCT引导下对玻璃体视网膜解剖关系的可视化改善,有可能提高手术安全性和效率。在早产儿视网膜病变和其他小儿视网膜血管疾病中,术中OCT对于区分视网膜劈裂和视网膜脱离以及突出玻璃体视网膜界面异常(这些异常可能导致牵拉性视网膜脱离的发生)至关重要。在视网膜脱离修复术中,术中OCT有助于识别细微的视网膜裂孔、残留的视网膜下液、残留的全氟碳、视网膜前膜和残留的玻璃体膜等其他发现。在黄斑手术中,术中OCT已证明在确认视网膜前膜和内界膜剥除是否完成或未完成以及区分板层黄斑孔和全层黄斑孔方面具有价值。OCT引导下的视网膜下液泡形成和基因载体递送对于确保遗传性视网膜变性的视网膜下基因递送准确定位至关重要。预计关于OCT兼容手术器械、实时三维容积OCT成像以及与术中OCT血管造影集成的研究,将进一步提高术中OCT在小儿玻璃体视网膜手术决策中的效用。
