TitleConsensus-based recommendations for OCTA reporting in uveitis.
PurposeTo establish a consensus in the nomenclature for reporting optical coherence tomography angiography (OCTA) findings in uveitis.
MethodsThe modified Delphi process consisted of two rounds of electronic questionnaires, followed by a face-to-face meeting conducted virtually. Seventeen specialists in uveitis and retinal imaging were selected by the executive committee.
The study endpoint was defined by the degree of consensus for each question: “strong consensus” was defined as > 90% agreement, “consensus” as 85-90% and “near consensus” as > 80% but <85%.
ResultsThere was a strong consensus to apply the term “wide field” to OCTA images measuring over 70 degrees of field of view, to use the terms “flow void” and “non detectable flow signal” to describe abnormal OCTA flow signal secondary to vessels displacement and slow flow respectively, to use the terms “loose” and “dense” to describe the appearance of inflammatory choroidal neovascularization, and to use the percentage of flow signal decrease to measure OCTA ischemia with a threshold greater than or equal to 30% as a “large area”.
ConclusionThis study sets up consensus recommendations for reporting OCTA findings in uveitis, which are suitable for use in routine clinical care and clinical trials.
