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 ...

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 ...

Your eyes are relatively small parts of your body, but they’re immensely complex. Your eyes are full of dozens of different parts, all of which work together to produce your vision. One of the most ...

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 at ...

PSI scientists have shed light on an important component of the eye: a protein in the rod cells of the retina which helps us see in dim light. Acting as an ion channel in the cell membrane, the ...

Human induced pluripotent stem cells (iPSCs) can be used to generate brain organoids containing an eye structure called the optic cup, according to a new study. The organoids spontaneously developed ...

Nearly everyone with diabetes for >20 years will develop diabetic retinopathy or uveitis, which are collectively among the most common causes of premature blindness. Melanocortin is a short peptide ...
