He added that a 5% deficit in retinal nerve fibre
layer thickness was unlikely to affect the visual function of young adolescents.
There was also a strong negative correlation between axial length and peripapillary retinal nerve fibre
layer thickness (r= -0.
Relation between size of optic disc and thickness of retinal nerve fibre
layer in normal subject.
There can also sometimes be damage to the actual nerve fibres
Instead the study found that long nerve fibre
connections were just as vital as short ones.
Professor Geoffrey Raisman, who developed the technique, said: "When a blow to the shoulder pulls nerve fibres
out of the spinal cord, it's like pulling a plug out of a socket.
Fundus examination of right eye showed clear media, disc was obscured with blurred margins, vessels showed tortuosity in inferior fundus, myelinated nerve fibres
were seen around the disc and extending superiorly along the arcuate fibres and involving nasal fundus of about 3 disc diameter and whole of inferior fundus.
Unfortunately, as people with MS age, remyelination decreases significantly, resulting in more nerve fibres
being permanently lost.
He has now shown this is true using a corneal confocal microscope: on average, the corneas of diabetic people with nerve damage have a lower density of nerve fibres
, and nerves are shorter than in healthy controls.
The corticospinal tract (CST) is a band of nerve fibres
that travels from the brain, through the brain stem and into the spinal cord.
When the nerve fibres
that carry smell become damaged, they are replaced by new nerve fibres
which re-enter the olfactory bulbs, the researchers explained in their study.
INTRODUCTION: Myelinated nerve fibres
are more frequent in females than in males and occur more often at the superior sectors of the nerve head and in the inferotemporal retina than in other areas.
In particular, they investigated changes in the nerves and tissues around the arthritic joint, by using specific markers to label the different types of nerve fibres
and allow them to be visualized with a fluorescence microscope.
progress from the receptors through tiny holes in the roof of the nasal cavity and come together to form two structures called the olfactory bulbs.
The US team showed that regenerating nerve fibres
can reform connections after being guided to the right targets.
