Table-I: Peripapillary retinal nerve fibre
layer thickness (n=300).
Savini G, Zanini M, Carelli V Sadun AA, Ross-Cisneros FN, Barboni P Correlation between retinal nerve fibre
layer thickness and optic nerve head size: an optical coherence tomography study.
Scientists carried out a computer analysis of databases containing detailed information of worldwide anatomical studies on primate and worm brains, and found that long nerve fibre
connections were just as vital to overall brain function as short ones.
Visual acuity is usually not affected in these cases; however Patient may have relative scotomas if sufficient number of myelinated nerve fibres
You are starving the nerve fibres
of nutritious oxygen," New Scientist quoted Efron as saying.
OECs help this process by re-opening the surface of the bulbs for the new nerve fibres
to enter — leading Raisman and his team to believe transplanting OECs into the damaged spinal cord could enable severed nerve fibres
On ophthalmologic examination, retinal medullated nerve fibres
were seen in the inferotemporal retina of left eye and in the superior as well as inferior sectors of the retina of right eye.
Normally, sympathetic nerve fibres
regulate blood flow in blood vessels.
From the bulbs, nerve fibres
travel to the olfactory centre in the brain.
But, like the wires in a wall plug, nerve fibres
have to be attached to the right places.
Professor James Fawcett's Cambridge-based team believes it is close to a clinical treatment that could allow nerve fibres
to regenerate within the spinal cord and encourage remaining nerve fibres
to work more effectively.
A substance called myelin protects the nerve fibres
of the central nervous system and helps the messages travel quickly and smoothly between the brain and the rest of the body.
