ObjectiveOur aim was to assess central and peripheral retinal and choroidal diseases using novel simultaneous multiwavelength-ultra-widefield (MW-UWF) fundus fluorescein angiography (FFA)/indocyanine green angiography (ICGA) with navigated central and peripheral swept-source optical coherence tomography (SS-OCT) technology.MethodsRetrospective evaluation was carried out of 30 consecutive patients (60 eyes) who underwent UWF red/green (RG), infrared (IR), FFA and ICGA with simultaneous navigated SS-OCT using Optos Silverstone (Optos PLC). Angiographic retinal and choroidal findings in vascular pathologies and their relationship with the vitreoretinal interface (VRI) were assessed.ResultsSimultaneous FFA with navigated SSOCT was performed in all patients and simultaneous FFA-ICGA with SS-OCT in 18 eyes (30%). Cross-sectional central and peripheral changes in the retina, choroid, and VRI corresponding with angiographic findings in several diseases were imaged.ConclusionFirst-in-human study of a new technology providing UWF RG/FFA/ICGA with simultaneous navigated central and peripheral SS-OCT can guide clinical management and provide new insights and understanding of central and peripheral retinal and choroidal disease.
