Whose fundus is this? What term do we give this arrangement and why does the animal organise the back of its eye like this?
This is a rabbit’s fundus – the question image was from a New Zealand White animal with a non-pigmented eye while this is from a normally pigmented Netherland Dwarf. We call this a merangiotic fundus – the rebbit has a long horizontal visual streak, giving it good vision all along the horizon, from whence might spring a hungrey fox! So it keeps its blood vessels and myelinated nerve fibres (the whiote streaks – but who knows why it has any mylelinated fibres – no other species bothers!) away from this lnie of high photoreceptor density.
