There's no tint of pain, real pain, in the sensations of the optic nerve
In the Articulata we can commence a series with an optic nerve
merely coated with pigment, and without any other mechanism; and from this low stage, numerous gradations of structure, branching off in two fundamentally different lines, can be shown to exist, until we reach a moderately high stage of perfection.
Just as a photographic plate receives a different impression of a cluster of stars when a telescope is part of the intervening medium, so a brain receives a different impression when an eye and an optic nerve
are part of the intervening medium.
The light from it had beat upon his sealed lids, and the eyes and the optic nerves
had pulsated to little, sparklike flashes, warm-coloured and strangely pleasing.
And it seemed to me that his eyes were strange, not only the expression, but the physical seeming, as though the optic nerves
and supporting muscles had suffered strain and slightly twisted the eyeballs.
Glaucoma is an eye disease that causes progressive irreversible damage of the optic nerve
and loss of vision field, leading to blindness.
If the eye pressure is not maintained, damage to the optic nerve
occurs which can then result in blindness, she said, adding that glaucoma is the world's second reason for blindness after cataract, while in Qatar it is considered the first cause of blindness in people over the age of 50 years.

We are the only actively recruiting stem cell study in retina or optic nerve
that has publications about actual study results listed on the clinicaltrials.
Several high-risk factors documented to be associated with extraocular recurrence have been identified upon Histopathological (HP) examination of enucleated eyes, which include invasion of post-laminar optic nerve
, trans-scleral migration, choroidal invasion and anterior chamber seeding.

The trigeminal nerve, the main one to the face and nose, lies alongside the optic nerve
which sends visual information from the eye to the brain.
