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

Have 30 percent optic nerve damage due to open angle glaucoma. How many years would it take to incur this amount of damage?

Have 30 percent optic nerve damage due to open angle glaucoma. How many years would it take to incur this amount of damage?

Variable: Glaucoma tends to be a slowly progressing condition. Damage typically occurs over many months or years; however. It also depends on how high your eye pressures are. People with very high eye pressures may develop damage more quickly. It is very important to have regular follow up with you eye md to ensure your eye pressures are controlled adequately. ...Read more

Can coughing, sneezing or long-term constant sniffing due to sinus drainage and habit cause optic nerve damage in glaucoma?

Can coughing, sneezing or long-term constant sniffing due to sinus drainage and habit cause optic nerve damage in glaucoma?

Glaucoma causes: Usually, the activities of daily living like you describe are NOT factors in the cause of glaucoma or the progression,severity, or treatment decisions.... FYI Cosopt is a drug and often has side effects..Have you asked about having the SLT glaucoma laser to replace the drops. Keep us posted. Dr.Sibley ...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

Glaucoma. Approximately how many years would it take before 30 percent damage is done to an optic nerve?

Glaucoma. Approximately how many years would it take before 30 percent damage is done to an optic nerve?

Hopefully never: Glaucoma is a condition in which the internal eye pressure is higher than the resistance of the optic nerves to withstand the pressure. The time to lose 30 percent varies with these two relationships. Hopefully the condition will be recognized, and treatment instituted so that no vision or nerves will be lost. Do not assume that you have some time for no treatment in this condition. ...Read more

In glaucoma, please define what minimal damage to the optic nerve is. A certain percentage of damage?

Detectable: The best research indicates that the optic nerve (as studied by scanning of its structure and observation of it surface architecture) will have some change indicating damage well before there is any functional problem. In this context then, minimal damage is observable change, prior to the onset of visual or functional measured change. ...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

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

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)

The optic nerve receives input from the retina and transmits information to the optic chasm and ultimately the occipital lobe of brain so that images can be ...Read more
