Sentences with phrase «within optic nerve»

Retinal ganglion cells downregulate gene expression and lose their axons within the optic nerve head in a mouse glaucoma model Soto, I., Oglesby, E., Buckingham, B.P., Son, J.L., Roberson, E.D., Steele, M.R., Inman, D.M., Vetter, M.L., Horner, P.J. & Marsh - Armstrong, N. (2008) Journal of Neuroscience, 28:548 - 61.

We seek in this proposal to determine whether a particular type of imaging is capable of assessing and reporting on the integrity of sub-microscopic structures within optic nerve fibers at an early stage of damage preceding their complete degeneration and loss from the eye.

We seek to determine whether a particular type of imaging, known as «polarization - sensitive» imaging, is capable of reporting on the integrity of sub-microscopic structures within optic nerve fibers at an early stage of damage from glaucoma, preceding their complete degeneration and loss from the eye.

Not exact matches

When I was 8 years old, it caused this disorder called hydrocephalus where the tumor is blocking the cerebral fluid in the brain and that automatically creates pressure within the ventricles and it starts affecting different parts of the brain, and in my case it damaged my optic nerve.

A healthy optic nerve has axons transmitting information from the eye to the brain along the nerve after considerable information processing and synaptic transmission between various cell types within the retina.

Several specimens of the species, Fuxianhuia protensa (left), contain dark areas within their eye stalks (see fossil, above right; gray areas in sketch, bottom right) that represent preserved clusters of neural tissue, including clumps along the optic nerve (labeled 1 through 3 in the sketch) and the brain (lowermost mass).

They discovered that zinc is released from cells within an hour after the optic nerve is injured acutely — but they were surprised to find that it didn't come from retinal ganglion cells.

I have been working in the field of glaucoma research, on pathophysiology and diagnostics, for the past 18 years, and have become increasingly interested in the use of advanced imaging techniques for characterization of glaucomatous changes within the retina and optic nerve head.

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.

Glaucoma is defined as increased pressure within the eye that causes degenerative changes in the optic nerve and retina with subsequent blindness.

They include diseases of the cornea (keratitis), the lens (cataract), increased pressure within the eye (glaucoma), any disease which reduces retinal sensitivity to light impulses (retinal atrophy), or any disease which affects the optic nerves or the sight - center of the brain (tumours, trauma).

Collie Eye Anomaly (CEA)-- a complex of congenital defects including choroidal hypoplasia, also called chorioretinal dysplasia — a thinning of the vascular tissue within the eye), optic disc coloboma / staphloma — incomplete development of the optic nerve where it enters the eye, and retinal dysplasia or detachment — sections of retina, the vision reception tissue, that are not properly attached to the wall of the eye.
