While rod cells help us see in dim or dark light, and cone cells
help us see bright light and color, the loss of cone cells
in particular can lead to irreversible blindness.
The cone cells
, which lie at the centre of your retina, provide you with colour vision but aren't very light-sensitive.
Those tubelike cells, called Muller cells, snake through the retina, where they pair with and support light-gathering cone cells
Our eyes work by receiving light that starts off a chain of complex chemical reactions in rod and cone cells
The implant is especially designed for patients with retinitis pigmentosa (RP) a condition, which damages the light-sensitive rod and cone cells
of the retina.
The scientists also found that many of the cone cells
that were on the verge of dying before the transplant appeared to regain or retain their function.
Artificial retina Responds to light like rod and cone cells
in a real retina.
Rod cells are more numerous than cone cells
and are crucial for vision at night and in other low lighting conditions.
I was told that my rod and cone cells
were gradually dying off and that eventually I would go blind.
Some patients also lose daylight vision and go blind completely as the color-sensing cone cells
of the inner retina slowly degenerate.
Nanometer-Scale Growth of Cone Cells
Tracked in Living Human Eye
London, Sep 22 (ANI): Scientists have successfully translated retinal cone cells
, vital for colour vision, into blind mice.
