N2 - Purpose: To summarize the results of a consensus meeting aimed at defining terminology for widefield imaging across all retinal imaging methods and to provide recommendations for the nomenclature used to describe related images. Design: An international panel with expertise in retinal imaging was assembled to define consensus terminology for widefield imaging and associated terminology. Participants: A panel of retina specialists with expertise in retinal imaging. Methods: Before the consensus meeting, a set of 7 images acquired with a range of imaging methods and representing both healthy and diseased eyes was circulated to the expert panel for independent assignment of nomenclature for each example. The outputs were assembled and used as the starting point for discussions occurring at a subsequent roundtable meeting. The anatomic location, field of view, and perspective provided by each image example was reviewed. A process of open discussion and negotiation was undertaken until unanimous terminology for widefield imaging was achieved. Main Outcome Measures: Definitions of widefield imaging applicable to multiple imaging methods. Results: Across a range of different imaging methods, the expert panel identified a lack of uniform terminology being used in recent literature to describe widefield images. The panel recommended the term widefield be limited to images depicting retinal anatomic features beyond the posterior pole, but posterior to the vortex vein ampulla, in all 4 quadrants. The term ultra widefield was recommended to describe images showing retinal anatomic features anterior to the vortex vein ampullae in all 4 quadrants. The definitions were recommended over other device-specific terminology. Conclusions: A consistent nomenclature for widefield imaging based on normal anatomic landmarks that is applicable to multiple retinal imaging methods has been proposed by the International Widefield Imaging Study Group. The panel recommends this standardized nomenclature for use in future publications.
