Doctor insights on: What Are The Treatments For Completely Damaged Optic Nerve Due To Glaucoma

Share

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

How does open-angle glaucoma damage the optic nerve?

How does open-angle glaucoma damage the optic nerve?

Slowly over time: Typically open angle glaucoma causes loss of ganglion cells with progressive thinning of the retinal nerve fiber layer faster than age-related loss slowly over time (thus generally asymptomatic), eventually leading to an enlarged optic nerve cup seen on eye exam. The optic nerve appears pale with loss of tissue and remodeled laminar changes. ...Read more

There is a procedure for opening the duct to relieve pressure to the optic nerve. Is it for glaucoma?

There is a procedure for opening the duct to relieve pressure to the optic nerve. Is it for glaucoma?

Glaucoma surgery: There are many types of surgery to treat glaucoma refractory to many drops available. They include laser treatment to surgery actually placing tubes into the eye. The treatment indicated would need to be determined by your ophthalmologist and/or glaucoma specialist. ...Read more

In early glaucoma what would be considered minimal damage to the optic nerve?

Glaucoma: Early glaucoma often has no visual symptoms and may only show up on a visual field or oct test. This stage is the most treatable, usually with eyedrop medication. ...Read more

Is glaucoma a disease related to optic nerve or aqueous humor?

Is glaucoma a disease related to optic nerve or aqueous humor?

Yes: If the aqueous humor flow is disturbed, usually by some degree of obstruction of the drains inside the eye. then the pressure elevates. This can cause compromise to the nerves and blood vessels at the optic nerve, with loss of vision if not treated. So glaucoma is a disease of the aqueous flow which affects the vision through the optic nerve. ...Read more

What can be used to heal a damaged optic nerve in glaucoma after surgery?

What can be used to heal a damaged optic nerve in glaucoma after surgery?

No repair: Unfortunately, vision loss due to damage to the optic nerve from glaucoma is not considered reversible. This is part of the reason that screening for glaucoma is an important public health issue -- treatment to prevent or decrease progression is well established, but there is not treatment to reverse vision loss from glaucoma. ...Read more

What should I know about glaucoma and optic nerve damage?

Glaucoma: Glaucoma is a condition where the optic nerve can not withstand the pressure within the eye. If it is determined that you have optic nerve damage and it is due to pressure, then you have glaucoma. You need to treat (or lower the pressure) to a point where no more damage occurs to prevent further damage and vision loss. ...Read more

In early glaucoma what would be considered minimal optic nerve damage?

In early glaucoma what would be considered minimal optic nerve damage?

No loss of function : Minimal optic nerve damage seen in early glaucoma is a structural change with or without visual field loss, depending on how the nerve is structurally changed. A visual field defect therefore isn't necessary to have in early glaucoma. Minimal nerve damage may show up as asymmetry, cup elongation, nerve fiber layer thinning, focal notching or excavation, vessel deformation, and other. ...Read more

For glaucoma to be caught early does that mean there must be no optic nerve damage?

For  glaucoma to be caught early does that mean there must be no optic nerve damage?

Not necessarily...: Glaucoma is the 'sneak thief of sight' and usually causes damage that occurs gradually but permanently. It's important that people at risk come in for regular exams so it can be diagnosed, and the damage 'nipped in the bud'. There can be some nerve damage incurred by the time glaucoma is caught relatively early, but the good news is the patient won't likely notice that their vision is affected. ...Read more

Glaucoma (Definition)

Glaucoma refers to a group of eye conditions that lead to damage to the optic nerve, the nerve that carries visual information from the eye to the brain. In many cases, damage to the optic nerve is due to increased pressure in the eye, also known ...Read more


Optic Nerve (Definition)
