为报告视网膜血管疾病的OCT血管造影(OCTA)发现制定共识命名法(例如,糖尿病视网膜病变,视网膜静脉阻塞)由国际专家。
基于Delphi的调查。
25位视网膜血管疾病和OCTA成像专家。
使用了共识发展的德尔菲法,包括两轮在线问卷,随后进行了面对面的会议。选择25位视网膜血管疾病和视网膜OCTA成像专家组成Delphi研究组视网膜血管疾病的OCTA命名法。共识的4个主要领域是:“广域(WF)”OCTA参数的定义,在常规和WF-OCTA上测量血管流量减少,OCTA发现的命名法,和OCTA在视网膜血管疾病管理和分期中的应用。研究终点由每个问题的共识程度来定义:“强共识”定义为≥85%的一致性,“共识”为80%至84%,“接近共识”为70%至79%。
视网膜血管疾病中OCTA命名法的共识和接近共识。
已达成共识,即WF-OCTA成像中流量百分比的有意义变化应为流量信号绝对成像面积的增加或减少≥30%,并且WF-OCTA减少的流量信号的“大面积”也应定义为绝对成像面积的≥30%。新血管和视网膜内微血管异常的存在,中央凹无血管区参数,“无流动区域”的存在和数量,对于糖尿病性视网膜病变的分期和分类,应增加对不同视网膜层血管密度的评估。绝对成像面积的流量减少≥30%应定义缺血性视网膜中央静脉阻塞。其他几个项目不符合协商一致要求,或在最后一轮讨论中被拒绝。
本研究为报告视网膜血管疾病的OCTA发现提供了国际共识建议。这可能有助于提高临床和临床试验的可解释性和描述性。这些设置中的进一步验证是有保证的,并且正在进行中。正在继续努力解决悬而未决的问题。
To develop a consensus nomenclature for reporting OCT angiography (OCTA) findings in retinal vascular disease (e.g., diabetic retinopathy, retinal vein occlusion) by international experts.
Delphi-based survey.
Twenty-five retinal vascular disease and OCTA imaging experts.
A Delphi method of consensus development was used, comprising 2 rounds of online questionnaires, followed by a face-to-face meeting conducted virtually. Twenty-five experts in retinal vascular disease and retinal OCTA imaging were selected to constitute the OCTA Nomenclature in Delphi Study Group for retinal vascular disease. The 4 main areas of consensus were: definition of the parameters of \"wide-field (WF)\" OCTA, measurement of decreased vascular flow on conventional and WF-OCTA, nomenclature of OCTA findings, and OCTA in retinal vascular disease management and staging. The study end point was defined by the degree of consensus for each question: \"strong consensus\" was defined as ≥85% agreement, \"consensus\" as 80% to 84%, and \"near consensus\" as 70% to 79%.
Consensus and near consensus on OCTA nomenclature in retinal vascular disease.
A consensus was reached that a meaningful change in percentage of flow on WF-OCTA imaging should be an increase or decrease ≥30% of the absolute imaged area of flow signal and that a \"large area\" of WF-OCTA reduced flow signal should also be defined as ≥30% of the absolute imaged area. The presence of new vessels and intraretinal microvascular abnormalities, the foveal avascular zone parameters, the presence and amount of \"no-flow areas,\" and the assessment of vessel density in various retinal layers should be added for the staging and classification of diabetic retinopathy. Decreased flow ≥30% of the absolute imaged area should define an ischemic central retinal vein occlusion. Several other items did not meet consensus requirements or were rejected in the final discussion round.
This study provides international consensus recommendations for reporting OCTA findings in retinal vascular disease, which may help to improve the interpretability and description in clinic and clinical trials. Further validation in these settings is warranted and ongoing. Efforts are continuing to address unresolved questions.
