Full-field swept source optical coherence tomography (FF-SS-OCT) system for in vivo evaluation of light evoked activation of photoreceptors (optoretinography) in mice

Abstract

Development of high resolution functional retinal imaging tools is of great interest to clinical and experimental ophthalmology because the alterations in retinal function, at cellular resolution, hold the promise of being more sensitive for disease diagnostic then the purely retinal morphology-based assays. In this work we present our initial design and implementation of mouse retinal imaging system that incorporates full-field (FF) swept- source (SS) optical coherence tomography (OCT) with dedicated light stimulation channel for high-speed measurements of light evoked responses in photoreceptors of mice. The Optoretinograpahy (ORG) results acquired with our FF-SS-OCT system are compared with those acquired with our standard raster scanning mouse ORG-OCT system.
