Abstract

Chorioretinal blood vessel morphology in mice is of great interest to researchers studying eye disease mechanisms in animal models. Two leading retinal imaging modalities - Optical Coherence Tomography (OCT) and Scanning Laser Ophthalmoscopy (SLO) - have offered much insight into vascular morphology and blood flow. OCT "flow-contrast" methods have provided detailed mapping of vascular morphology with micrometer depth resolution, while OCT Doppler methods have enabled the measurement of local flow velocities. SLO remains indispensable in studying blood leakage, microaneurysms, and the clearance time of contrast agents of different sizes. In this manuscript we present results obtained with a custom OCT/SLO system applied to visualize the chorioretinal vascular morphology of pigmented C57Bl/6J and albino nude (Nu/Nu) mice. Blood perfusion maps of choroidal vessels and choricapillaris created by OCT and SLO are presented, along with detailed evaluation of different OCT imaging parameters, including the use of the scattering contrast agent Intralipid. Future applications are discussed.
