0 the group of nerve fibres (= structures like threads) that pass signals from the retina at the back of each eye to the brain --
The conjunctiva was cut and the globe retracted with forceps to expose the optic nerve.
A quantitative study of reinnervation of the goldfish optic tectum following optic nerve crush.
The teleost optic nerve has been the focus of numerous studies investigating regeneration and synaptogenesis.
Therefore, this pedigree may be a model for a nonglaucomatous optic nerve disease or other anomaly.
The dashed line depicts the central limit of each hemiretina and the open circle represents the position of the optic nerve head.
The region indicated as central retina was located approximately 0.5 mm from the optic nerve head.
The density increases quite steeply from 4000 cells 0mm 2 to 12,000 cells 0mm 2 in a region just dorsal to the optic nerve head.
This suggests that the surgical preparation procedures produced some optic nerve damage.
