1. A method for non-invasive assessment of intracranial pressure, said method comprising,
providing an image recording device,
recording at least one image of a retina part of an eye of a person using said image recording device,
identifying, in said at least one image, at least one artery and at least one vein associated with said artery,
determining, in said image, a first characteristic diameter value for said identified artery,
determining, in said image, a second characteristic diameter value for said identified vein,
calculating an arteriovenous ratio based on said first and second characteristic diameter values, and
outputting an assessment of said intracranial pressure based on comparing said arteriovenous ratio with a threshold value.
