This Folder contains the Matlab files used to simulate blood flow and oxygen transport in the retina associated with the publication “LRG1 initiates the onset of diabetic retinopathy in mice”. A short readme file is included which briefly describes the main component of the folder as well as a demo simulation. For more information on the methods used and the context (including scope, funding and specific acknowledgement), please refer to the dedicated supplementary material or contact maxime.berg@ucl.ac.uk (alt. maxime.berg@cnrs.fr) or giulia.derossi@ucl.ac.uk.
