When the eyeball is removed is the optic nerve also removed?

Nerve (Definition)

The brain and spinal cord communicates with what is occurring in the internal organs and limbs by nerve fibers where are like electrical wires with insulation (myelin) and the "copper" (axon). Within brain and spinal cord these nerves connect to other nerves via synapses on both axons and dendrites. A nerve can carry information regarding sensations, and ...Read more

If an optic nerve was damaged, what doctor should I seek for eye doctor or a nerve doctor?

If an optic nerve was damaged, what doctor should I seek for eye doctor or a nerve doctor?

Actually- maybe both: Depends on what you mean when you say "optic nerve damaged" & as importantly what is the resulting disturbance in vision consequent to this damage. In other words, if the nerve is physically damaged such as by trauma then, an ophthalmologist is needed but if a clot causes a stroke in the eye & that's the cause of the damage then, a neurologist is likely better. Or both might be of value depending ...Read more

Is it possible to save an eye from trauma if the optic nerve is intact?

Is it possible to save an eye from trauma if the optic nerve is intact?

Yes: It all depends on the extent of the injury. If the nerve is intact and you have vision in the eye it can be saved, but there may be injury to the globe, muscles, cornea, lens, or retina. Any significant trauma to eye that would cause such symptoms should be evaluated by an ophthalmologist. ...Read more

Opthamlgist saw thinning optic nerve in l eye. Didn't know what q's to ask at the time. Progressive? What can I do to avoid glaucoma? Please educate me

Careful monitoring: Cause of thinning is important to know. There are several specific tests for glaucoma, but it is not always obvious in early stages. Eye pressure is the most simple to test but incomplete. To avoid or reduce progressive damage from glaucoma, careful monitoring by an ophthalmologist and treatment if necessary by eyedrops and/or surgery can be effective for controlling eye pressure. ...Read more

How does an eye doctor check the optic nerve?

How does an eye doctor check the optic nerve?

Observation: The optic nerve is the cable connecting the retina to the brain, carrying the visual information for sight. Ophthalmologists look at its entry structure at the back of the eye, check the pupils for proper reaction, and measure visual function including the field of vision to test whether the nerve is normal. A few imaging machines can help with this (termed otc). ...Read more

Everytime I bend over I get a pain behind my left eye as soon as I stand up it goes away. I also have a swollen optic nerve in the eye. What is wrong?

Intracranial HTN: Seems like you may have high intracranial pressure. Lying down, bending down raises the pressure, standing lowers it. Papilledema is classic for high icp. You need to be seen by an ophthalmologist to determine cause... Oral contraceptives, hormones, obesity, vitamins, steroids, tumors can all lead to high icp. ...Read more

Optic neuritis is inflammation of the optic nerve, the nerve that controls your vision. If you continue the medication you could develop permanent vision loss. Your dermatologist can offer other options instead of accutane. ...Read more

Possible causes of enlarged optic nerve. Eye dr days no glaucoma, referred me to a neurologist?

Several causes: The most common cause of an enlarged optic nerve is familial - runs in families. Your eye doctor may have identified nerve swelling termed papilledema, which is due to increased pressure of the cerebrospinal fluid. Causes for this include, obstruction, tumors, vascular problems and trauma. The neurologist will know which tests to run to discover the cause. ...Read more

Sounds right: Your eye doctor wants to follow up to see if any changes occur in the next month. Sounds like you are lucky that MRI doesn't show changes but OCT imaging may show more. So each step leads to the next step in your management. Not sure what you meant by 'buy empty space? ' Please clarify. Thanks! ...Read more

This: This could have just been congenital pigment deposition laid down prior to birth that has degenerated over time and has left what we call optic nerve drusen. Should not have any effect on your vision, but if you are concerned, please see a glaucoma or retina specialist who should be able to give you a better idea. ...Read more

Visual field testing and optical coherence tomography can determine the extent of any problem, and then can be monitored over time. These tests can be performed by an ophthalmologist. Sometimes disc drusen are associated with retinal problems, but not macular degeneration. ...Read more
