Team identifies a form of congenital night blindness in dogs

People with congenital stationary night blindness, or CSNB, have normal vision during the day but find it difficult or impossible to distinguish objects in low light. This rare condition is present from birth and can seriously ...

Seeing starfish: The missing link in eye evolution?

A study has shown for the first time that starfish use primitive eyes at the tip of their arms to visually navigate their environment. Research headed by Dr. Anders Garm at the Marine Biological Section of the University ...

Optics: Statistics light the way

Millions of years of evolution have molded our eyes into highly sensitive optical detectors, surpassing even many man-made devices. Now, Leonid Krivitsky and his co-workers at the A*STAR Data Storage Institute and the A*STAR ...

Architecture of rod sensory cilium disrupted by mutation

Using a new technique called cryo-electron tomography, two research teams at Baylor College of Medicine have created a three-dimensional map that gives a better understanding of how the architecture of the rod sensory cilium ...

First mouse, now human, lab-grown eye tissue

Producing retinal tissue from human embryonic stem cells is now possible thanks to a team of researchers led by Yoshiki Sasai of the RIKEN Center for Developmental Biology in Kobe, Japan.

Circadian clocks in a blind fish

Do animals that have evolved for millions of years underground, completely isolated from the day-night cycle, still "know" what time it is? Does a normal circadian clock persist during evolution under constant darkness? A ...

Modeling retinitis pigmentosa with iPS cells

Retinitis pigmentosa (RP) is a cluster of genetically determined eye disorders that cause visual defects such as night blindness and narrowing of the field of vision, due to progressive loss of rod photoreceptors. As many ...
