Abstract
Irregularities of ocular pulsatility are associated with some of the most severe eye diseases. Here we present fundus elastography (FUEL) based on optical coherence tomography (OCT) for the quantitative assessment and depth-resolved mapping of pulsatile dynamics in the murine retina and choroid. Our FUEL approach is based on an analysis of the complex OCT signal dynamics across repeated frame acquisitions. We demonstrate in vivo FUEL imaging in the retinas of wildtype mice and mouse models of retinal diseases and reveal subtle structural deformations related to ocular pulsation. Our data in mouse eyes hold promise for a powerful retinal elastography technique that may enable a new paradigm of OCT based measurements and image contrast.
