Neurons in the bird eye’s inner retina lack a blood supply. Finding how these neurons function without oxygen reveals a role for an enigmatic eye structure. Read the paper: Oxygen-free metabolism in ...

Scientists have known for years that a lattice of blood vessels nourishes cells in the retina that allow us to see -- but it's been a mystery how the intricate structure is created. Now, researchers ...

Another milestone in eye imaging has been achieved. Polish scientists have developed a technique that enables visualization of the retina and choroid at discrete depths. Modern imaging of eye tissues ...
