Spots result due to the degeneration of the light-sensitive cells in that region.
In dry AMD, the light-sensitive cells in the macula slowly break down causing central vision to diminish over time.
Underneath, these rays enter a dense forest of 125 million light-sensitive cells.
A CCD camera contains millions of light-sensitive cells that are arranged in a rows and columns to form a matrix.
AMD is the result of the macula-a spot in your eye loaded with millions of light-sensitive cells- becoming damaged.
The eyes are also much more light-sensitive cells than the human eye, it gives the animal the ability to detect objects and even see colors at night.
I looked around the room and noticed that my photoreceptors(light-sensitive cells in the retina) were still bleached out.
Its eyes are made up of 30,000 visual units called ommatidia,each one containing a lens and a series of light-sensitive cells.
The material they developedhas one side that contains tiny light-sensitive cells that are sensitive to the colors of the environment.
These eyes consist of 30,000 visual elements called ommatidia,each of which contains the lens and a number of light-sensitive cells.
AMD affects more than 600,000 people in Britain andoccurs when the specialised light-sensitive cells at the very centre of the retina- a region called the macular- become damaged.
The light-sensitive cells at the back of the eye are more sensitive to the light emitted by screens- which tricks the body into thinking that it's still daytime, so it disrupts the production of melatonin.
People with this condition have amutation in a gene that affects the function of the retina, the light-sensitive cells at the back of the eye that are essential for normal vision.
The fact that blue light penetrates all the way to the retina(the inner lining of the back of the eye) is important, because laboratory studies have shown that too muchexposure to blue light can damage light-sensitive cells in the retina.
The study demonstrated that it is possible to restore lost light-sensitive cells in the eye, by putting a gene into the retinal cells and using it to reorientate them.
But sildenafil also inhibits a related enzyme called phosphodiesterase type 6(PDE6),which is found in retinal cells, the light-sensitive cells at the back of the eye.
Increased risk of macular degeneration-Because blue light may reach and contribute to damage the light-sensitive cells in the retina, while being more and more exposed, this may be one more important contributing factor to permanent vision loss.
Rather than being considered a single disease, retinitis pigmentosa instead isviewed as a group of diseases affecting how light-sensitive cells in the back of the eye function.
Not only does a fly's compound eye show the samehexagonal packing of facets as a bubble raft, but the light-sensitive cells within each of the individual lenses are also clustered in groups of four that look just like soap bubbles.
In its tail there are light-sensitive nerve cells that pick up the reflections of fish, giving it another set of“eyes”.
If your eyes are normal,then you can differentiate between different colors, but if your eyes lack cone cells or light-sensitive chemicals, then you can see only two primary colors.
Neuroscientist Ed Boyden shows how, by inserting genes for light-sensitive proteins into brain cells, he can selectively activate or de-activate specific neurons with fiber-optic implants.
A more recent and less common technique called photodynamic therapy uses a certain type of light anda special(light-sensitive) chemical to kill cancer cells.
When these nerve cells are exposed to blue light, the light-sensitive protein is activated, allowing those brain cells to communicate with each other and modify the animal's behavior.
The cells at the back of the eyes contain a light-sensitive protein that picks up certain wavelengths of light.
A team of US scientists from the National Institutes of Health used a gene injection to reprogramme dumb non-seeing retinal cells, and then use them to replace damaged light-sensitive rod cells.
For example, animals with Parkinson's disease can be cured of theirinvoluntary tremors by shining light on brain cells that have been specially engineered making them light-sensitive.
Isacoff and Flannery came upon the simple fix after more than a decade of trying more complicated schemes,including inserting into surviving retinal cells combinations of genetically engineered neurotransmitter receptors and light-sensitive chemical switches.
When it's exposed to UV light, that triggers special light-sensitive receptors called rhodopsin, which stimulate the production of melanin to shield cells from damage.
