Expert consensus on fundus fluorescein angiography reporting in ophthalmology: a Delphi study

PURPOSE: Fundus fluorescein angiography (FFA) is an important tool in evaluating retinal vascular disease. In the era of optical coherence tomography angiography (OCTA), however, expert preferences regarding the comparative utility of FFA and OCTA remain unclear. Additionally, despite FFA's widespread use, variability exists in the terminology used to describe angiographic findings. This study aimed to establish expert consensus on clinical indications for FFA versus OCTA and to provide consensus definitions of key angiographic terms. METHODS: Using a two-round modified Delphi process, 25 retinal subspecialists provided perspectives on the clinical indications for FFA in the assessment of a range of retinal vascular conditions. They also evaluated proposed definitions for FFA findings in retinal vascular diseases. Consensus was defined as ≥80% agreement and near consensus as 70%-79%. RESULTS: . CONCLUSION: This study presents contemporary perspectives on the clinical indications for FFA in an era in which OCT and OCTA are widely available. It also provides a lexicon for FFA reporting in retinal vascular diseases based on expert consensus.
