Sentences with phrase «nerve cells of the retina»

Imagine how difficult it is for a patient and their family and friends when they lose vision, as is the case in a disorder such as age - related macular degeneration (AMD), where the unexpected sprouting of weak and leaky new blood vessels leads to death the ath of the nerve cells of the retina.

Final Report Summary: Glaucoma is a silent disease that, over time, kills the nerve cells of the retina leading to irreversible blindness.

Not exact matches

Did it started off as a mass of white ball, then it slowly started developing nerves, retina, a cornea, and essentially a complex apparatus for capturing light and transmitting it via nerve cells to the brain?

That light goes through the transparent liquid behind the lens and strikes the retina, a thin film of light - sensitive nerve cells that line the back of the eye.

Blind Spot A layer of nerve cells coats the innermost surface of the retina.

Johns Hopkins researchers have developed a method to efficiently turn human stem cells into retinal ganglion cells, the type of nerve cells located within the retina that transmit visual signals from the eye to the brain.

These electrodes pulse to stimulate cells in the retina, transmitting visual information along the optic nerve to the brain, creating the perception of patterns of light.

The impulse starts with excitation of the left retina, then travels down the optic nerve to cells in the midbrain and brain stem, which excite neurons near both eyes that cause the pupils to constrict.

The nerve cells of the central nervous system (CNS), which is composed of the spinal cord, the brain, and the retina, must be supplied with sufficient oxygen and nutrients through the blood vessel system during development and their subsequent function.

When a rod cell in the retina absorbs light, a cascade of reactions results in a nerve signal.

Their focus is the retina, the thin tissue in the back of the eye containing the photoreceptors and nerve cells.

In fact, so much of the progress that we're making in laboratories, including mine, is on developing neuroprotective therapies that can protect the retina from degeneration, regenerate optic nerve fibers all the way back to their targets in the brain, and even replace damaged retinal ganglion cells with self - therapies that completely rebuild the optic nerve.

The third promising biomarker involves imaging of the inner retina, including vascular, nerve fiber and ganglion cell components.

This research points to exciting new possibilities for preventing or reversing the disabling vision loss caused by age - related macular degeneration, diabetic retinopathy, retinitis pigmentosa, glaucoma, and other diseases that damage the retina, the layer of light - sensitive nerve cells that line the back of the eye.

On the surface, the disease appears relatively simple, with high pressure (intra-ocular pressure, or IOP) within the eye associated with the death of cells in the retina and optic nerve dysfunction.

But biopsying tumors in the retina, the thin layer of nerve cells in the back of the eye, risks spreading cancer by unleashing tumor particles into the rest of the body and the brain.

Layers of the retina: RPE, retinal pigment epithelium; PR, photoreceptors; ONL, outer nuclear layer; OPL, outer plexiform layer; INL, inner nuclear layer; IPL, inner plexiform layer; GCL, ganglion cell layer; NFL, nerve fiber layer.
