UNASSIGNED: Wide-field or wide-angle imaging is defined as greater than 50° field of view. Modern devices can reach far beyond this reporting fields of view up to 267°, when utilizing montage features, with increasingly impressive resolution. Wide-field imaging modalities include fundus photography, fluorescein angiography (FA), fundus autofluorescence (FAF), indocyanine angiography (ICG), spectral domain optical coherence tomography (SD-OCT), and recently wide-field OCT Angiography (OCTA). These imaging modalities are increasingly prevalent in practice. The wide-field systems include laser, optical, and lens based systems that are contact or non-contact lens systems each with its own benefits and drawbacks. The purpose of this review is to discuss commonly used wide-field imaging modalities for retinal and choroidal tumors and demonstrate the use of various widefield imaging modalities in select ocular oncology cases.
UNASSIGNED: Clinical examination remains the gold standard for the evaluation of choroidal and retinal tumors. Wide-field imaging plays an important role in ocular oncology for initial documentation, surgical planning, determining the relationship of the tumor to adjacent ocular structures, following tumor size after treatment, and monitoring for recurrence.
■广角成像被定义为大于50°的视场。现代设备可以远远超出这个报告视野高达267°,当利用蒙太奇特征时,越来越令人印象深刻的决议。广角成像方式包括眼底摄影,荧光素血管造影(FA),眼底自发荧光(FAF),吲哚菁血管造影(ICG),谱域光学相干层析成像(SD-OCT),以及最近的广域OCT血管造影(OCTA)。这些成像模式在实践中越来越普遍。宽视场系统包括激光,光学,和基于镜片的系统,其是接触或非接触镜片系统,每个系统都具有其自身的优点和缺点。这篇综述的目的是讨论视网膜和脉络膜肿瘤的常用宽视场成像方式,并证明在某些眼部肿瘤病例中使用各种宽视场成像方式。
■临床检查仍然是评估脉络膜和视网膜肿瘤的金标准。宽视场成像在眼部肿瘤学的初步文献中起着重要作用,手术计划,确定肿瘤与相邻眼结构的关系,治疗后肿瘤大小,并监测复发。
