And because their retina doesn’t need a hole to accommodate the optic nerve, they have no blind spot. In our own retinas, nerves and vessels are random in their spacing and irregular in their shape.

Eyes with large optic discs have larger neuroretinal rim areas, larger CDRs, less nerve fiber crowding, more optic nerve fibers, and higher retinal photoreceptor counts than those with smaller ...

Soft, implantable optical fibres that move and stretch with the body have been developed by researchers from the US for use in optogenetics studies. The tool will help scientists identify the ...

In one study, sensitivity increased from 85% to 95%. Under the revised criteria, optic nerve lesions may be documented using MRI, optical coherence tomography (OCT), or visual evoked potentials (VEP).

Axons -- nerve fibres -- in the adult central nervous system (CNS) do not normally regenerate after injury and disease, meaning that damage is often irreversible.

In addition, optical coherence tomography imaging of the optic nerve head (ONH) and retinal nerve fiber layer (RNFL) as well as the macular ganglion cell complex (GCC) were obtained. Finally ...

The researchers crushed the optic nerves shortly after birth, and found that in young mice – less than 14 days old – between 40% and 70% of the injured optic nerve fibres regrew to reach their ...

For OCT, an optic nerve lesion was defined as an intereye thickness asymmetry (IEA) of at least 5 μm for peripapillary retinal nerve fiber layer (pRNFL) and at least 4 μm for ganglion cell and ...

Optical Coherence Tomography (OCT) This diagnostic test measures the thickness of the retinal nerve fiber layer, which is thinned by optic neuritis.
