Abstract：
In the last decade, optical coherence tomography angiography (OCTA) has become part of the clinical management of retinal vein occlusion (RVO), proving in itself a useful technique for both the prediction of visual acuity (VA) outcomes and the risk of complications. In fact, OCTA has been proven a valid imaging technique in detailed assessment of foveal and parafoveal microvascular status in both acute and chronic RVO. Quantitative OCTA data have shown a significant correlation not only with final VA but also with the extension of peripheral ischemia, which represents a major risk factor for macular edema recurrence and neovascularization onset. Finally, wide-field OCTA represents a promising noninvasive technique for the assessment of peripheral ischemia. The aim of this review is to report the main literature findings about microvascular changes and clinical applications of OCTA in the context of RVO-induced peripheral ischemia.
摘要：
在过去的十年里，光学相干断层扫描血管造影（OCTA）已成为视网膜静脉阻塞（RVO）临床治疗的一部分，证明了其本身对于预测视力（VA）结果和并发症风险的有用技术。事实上,OCTA已被证明是一种有效的成像技术，可详细评估急性和慢性RVO的中央凹和副凹微血管状态。定量OCTA数据显示，不仅与最终的VA，而且与外周缺血的扩展，这是黄斑水肿复发和新生血管形成的主要危险因素。最后,广域OCTA是一种评估外周缺血的有前景的非侵入性技术.这篇综述的目的是报道有关OCTA在RVO引起的外周缺血中的微血管变化和临床应用的主要文献发现。
