Intraoperative optical coherence tomography (OCT) has gained traction as an important adjunct for clinical decision making during vitreoretinal surgery, and OCT angiography (OCTA) has provided novel insights in clinical evaluation of retinal diseases. To date, these two technologies have not been applied in combination to evaluate retinal vascular disease in the operating suite.
To conduct microscope-integrated, swept-source OCTA (MIOCTA) in children with retinal vascular disease.
DESIGN, SETTING, AND PARTICIPANTS: In this case report analysis, OCT imaging in pediatric patients, MIOCTA images were obtained during examination under anesthesia from a young boy with a history of idiopathic vitreous hemorrhage and a female infant with familial exudative vitreoretinopathy.
Side-by-side comparison of research MIOCT angiograms and clinically indicated fluorescein angiograms.
In 2 young children with retinal vascular disease, the MIOCTA images showed more detailed vascular patterns than were visible on the fluorescein angiograms although within a more posterior field of view. The MIOCTA system allowed visualization of small pathological retinal vessels in the retinal periphery that were obscured in the fluorescein angiograms by fluorescein staining from underlying, preexisting laser scars.
This is the first report to date of the use of MIOCTA in the operating room for young children with retinal vascular disease. Further optimization of this system may allow noninvasive detailed evaluation of retinal vasculature during surgical procedures and in patients who could not cooperate with in-office examinations.
术中光学相干断层扫描(OCT)已成为玻璃体视网膜手术中临床决策的重要辅助手段,而OCT血管造影(OCTA)为视网膜疾病的临床评估提供了新的见解。迄今为止,这两种技术尚未联合应用于手术室中评估视网膜血管疾病。
对患有视网膜血管疾病的儿童进行显微镜集成扫频源OCTA(MIOCTA)检查。
设计、地点和参与者:在本病例报告分析中,对儿科患者进行OCT成像,在麻醉检查期间,从一名有特发性玻璃体出血病史的小男孩和一名患有家族性渗出性玻璃体视网膜病变的女婴身上获取了MIOCTA图像。
对研究性MIOCT血管造影和临床指示的荧光素血管造影进行并排比较。
在2名患有视网膜血管疾病的幼儿中,MIOCTA图像显示的血管模式比荧光素血管造影更详细,尽管视野更靠后。MIOCTA系统能够显示视网膜周边小的病理性视网膜血管,而这些血管在荧光素血管造影中被下方先前存在的激光瘢痕的荧光素染色所掩盖。
这是迄今为止关于在手术室中对患有视网膜血管疾病的幼儿使用MIOCTA的首次报告。该系统的进一步优化可能允许在手术过程中以及无法配合门诊检查的患者中对视网膜血管系统进行无创详细评估。
