Causes of optic nerve thinning Answers from Doctors

Optic nerve thinning, also termed cupping, can be due to elevated pressur.. Optic neuritis, an inflammation (swelling) of the optic nerve caused by multiple sclerosis. A hereditary condition in which the person experiences loss of vision first in one eye, and then in the other (known as Leber's hereditary optic neuropathy). Improper formation of the optic nerve, which is a congenital problem (the person is born with it)

The doctor says my optic nerve is thin. What can cause this? How worried should I be? View answer. Answered by : Dr. Dadapeer K ( Ophthalmologist) what causes a congested optic nerve - in one eye, and a congested optic nerve that bulges in the other eye and what are the potential problems that can be caused by.. This is called ischemic optic neuropathy. The problem most often affects older adults. The optic nerve can also be damaged by shock, toxins, radiation, and trauma. Eye diseases, such as glaucoma, can also cause a form of optic nerve atrophy

Optic Atrophy: Causes, Symptoms, Diagnosis & Outcom

Photo showing how degeneration of the optic nerve narrows the field of vision, starting with loss of vision in the periphery, which then ultimately also causes loss of central vision. Glaucoma is actually a group of diseases, but the common feature among all types of glaucoma is optic nerve degeneration The exact cause of optic neuritis is unknown. It's believed to develop when the immune system mistakenly targets the substance covering your optic nerve, resulting in inflammation and damage to the myelin. Normally, the myelin helps electrical impulses travel quickly from the eye to the brain, where they're converted into visual information

That's hard to say because there are some conditions that cause atrophy in the brain or optic nerve that are caused by general degeneration and not inflammation or lesions. So I think that's why your ophthalmologist wants to wait until you see the neuro to try to figure out what's going on Optic nerve disorders may be caused by developmental factors, such as genetic or abnormal development, or by acquired factors, such as trauma or disease. How are optic nerve disorders diagnosed? Tests for optic nerve disorders may include

What causes a thin optic nerve - Doctor answers on

Other rare causes of pseudoglaucomatous optic nerve changes include late changes after methanol-toxicity and late changes in tertiary syphilis. The history is usually helpful in toxic optic neuropathy, but identification of syphilis may require laboratory testing If the temporal rim of the optic nerve is very thin or is sloped, then glaucoma is more likely. The doctor also pays close attention to the color of the optic nerve because some other diseases of the optic nerve can cause enlarged cups but also cause the nerve to look pale (multiple sclerosis, brain tumors, strokes to the nerve or brain, etc.) The optic nerve atrophy was correlated with the RNFL thinning, macular volume loss, visual acuity, visual field mean deviation, and whole field VEP amplitude but not latency. These findings suggest that axonal loss contributes to optic nerve atrophy following a single attack of optic neuritis

Optic nerve thinning does not cause headaches. It only causes vision problems like blurred vision and reduced peripheral vision. Optic nerve thinning occurs when the nerves which carry visual.. The Glaucoma Research Foundation says glaucoma is a common cause of optic cupping. When you have glaucoma, your eye is filled with an unusual amount of fluid, and it puts immense pressure on all the tissues in your eye. Nerves are delicate, and they can't stand the pressure. They will die, and that leaves your optic nerve exposed

Suggest treatment for thinning of optic nerve causing loss of vision. One of my daughter s friend has lost 9/10 view on an eye and his starting to lose something on the other one because of a thinning of the optical nerve, the loss has occurred suddenly and in a week View answer. Glaucoma suspect There are numerous causes of optic atrophy, including direct compression of the nerve or chiasm by a mass lesion, infarction, trauma, toxicity inflammation, infiltration, and metabolic dysfunction, to name a few. Compressive Lesions That Cause Disc Pallor. Compressive neuropathy by a mass lesion often can result in disc pallor and optic atrophy

Optic atrophy (optic neuropathy) is a term used to refer to the end stage of a number of conditions that can cause optic nerve damage. The optic nerve is composed of a bundle of nerve fibers, each. Restore Vision Clinic in Germany treats vision loss caused optic nerve damag Optic nerve thinning, also termed cupping, can be due to elevated pressure inside the eye which is termed glaucoma. I assume the doctor who discovered this was an ophthalmologist (I hope) who would initiate a work up to see if this is the cause. You should be seeing, for this, an ophthalmologist. 331 views Reviewed >2 years ago

Glaucoma is a group of eye conditions that damage the optic nerve, the health of which is vital for good vision. This damage is often caused by an abnormally high pressure in your eye. Glaucoma is one of the leading causes of blindness for people over the age of 60. It can occur at any age but is more common in older adults Optic Nerve Damage Causes/Symptoms. Kelly has optic nerve damage, or optic nerve atrophy, that can be caused by trauma or diseases such as glaucoma and multiple sclerosis (MS). Let's take a closer. I have optic nerve thinning (same as cuppling) to the optic nerve. I asked my eye doc is this related to MS... he says its part of glaucoma disease.. I do not have high pressure.. my eye pressure is 12 and normal is anything under 20 ( ithink) anyway, I have a call out to my eye doctor for him to explain this more to me. I do have MS. Thinning has been minimal. Last OCT exam should a little more thinning in one eye. My pressures are normal and no change. So I've looked up some information about this online, and I don't understand the reason for continuing these tests if there is no obvious changes and if the underlying cause is basically untreatable

The anatomy of the optic nerve makes it a sensitive marker for problems inside the brain. This nerve connects the back of each eyeball and its retina to the brain. In its short span between the brain and the eye, the optic nerve's whole surface is bathed in cerebral spinal fluid. This fluid protects the nerve from sudden movement Thinning of the optic nerve indicates that it is being damaged by elevated intraocular pressure. When OCT test results show that the optic nerve is thinning, this is a symptom of glaucoma. In addition to glaucoma, OCT is useful in diagnosing other eye conditions such as diabetic retinopathy and age-related macular degeneration

  1. Drusen are small yellow deposits of fatty proteins (lipids) that accumulate under the retina.. The retina is a thin layer of tissue that lines the back of the inside of the eye, near the optic nerve
  2. The buildup of fluid in the eye causes increased pressure within the eye (intraocular pressure, IOP) which pushes on the optic nerve, and consequently, with time, causes damage to the nerve. Any damage to the optic nerve will result in partial or complete, permanent, vision loss. Normal tension glaucoma (NTG) is a form of open angle glaucoma.
  3. Optic neuritis is an inflammation of the optic nerve. Causes include infections and immune-related illnesses such as multiple sclerosis. Sometimes the cause is unknown. Optic nerve atrophy is damage to the optic nerve. Causes include poor blood flow to the eye, disease, trauma, or exposure to toxic substances. Optic nerve head drusen are.
  4. Optic neuropathy is damage to the optic nerve, involving changes to blood flow, harm to structures in the eye, and other underlying causes. ( Learn More) Symptoms are mostly vision loss, which can be total and sudden. It may involve clouding or blurriness, loss of color vision, loss of peripheral vision, and vision fading in and out

Symptoms of optic nerve compression. When you have optic nerve compression, the most common symptom is gradual worsening or loss of your vision. Other symptoms may include: Dark, dimmed, or blurred vision. Problems with sharpness and color perception. It is rare to have sudden vision loss with optic nerve compression, although it can occur when. Optic atrophy, pallor of the optic nerve head, is a sign found in patients with visual loss due to pathology of the optic nerve or retinal ganglion cells. There are many causes. This article discusses the differential diagnosis of optic atrophy The optic nerve is more pale than cupped. Visual field loss is progressing more rapidly than expected for glaucoma. Visual field loss is progressing despite normal IOP or IOP that's under control. Severity of cupping doesn't match the visual field defect. The OCT of the optic nerve and macula does not correlate with the visual fields The underlying cause isn't completely understood, but experts believe that a viral infection may trigger the immune system to attack the optic nerve as if it were a foreign invader. Loss of vision in optic neuritis commonly reaches its maximum effect within a few days and starts improving within 4 to 12 weeks Optic atrophy refers to the death of the retinal ganglion cell axons that comprise the optic nerve with the resulting picture of a pale optic nerve on fundoscopy. Optic atrophy is an end stage that arises from myriad causes of optic nerve damage anywhere along the path from the retina to the lateral geniculate. Since the optic nerve transmits retinal information to the brain, optic atrophy is.

Improper segmentation causes a false reading of a thin nerve fiber layer, and it shows up on the report as red. • The visual field learning effect. This can have a big impact, notes Christopher A. Girkin, MD, chairman of the Department of Ophthalmology and Vision Sciences at Callahan Eye Hospital, University of Alabama Thinning of optic disc neuroretinal rim so that optic disc appears pathologically cupped (excavated) Usual cause is glaucoma. Glaucoma causes slow death of optic nerve axons and their supporting glia partly because of chronically high intraocular pressure. Visual fields eventually become constricted, but only when neuroretinal rim is very thinned

Optic neuritis refers to inflammation in the optic nerve, and it is a common symptom in people with MS. MS is not the only cause of optic neuritis, however, and a thorough diagnosis is important. The optic nerve connects the eye to the brain. Our sight relies on the optic nerve transmitting information on shape, colour and pattern from the back of the eye (retina) to the brain's visual centres. Optic neuritis is inflammation of the optic nerve that causes blurred, grey and dim vision Retinal Nerve Fiber Layer. Retinal nerve fiber layer (RNFL) thinning - reflecting loss of ganglion cell axons that leave the retina as the optic nerve and synapse onto the lateral geniculate nucleus - as revealed by OCT, is thought to be a good model of brain neurodegeneration, since retinal cells are unmyelinated, and so any thinning directly reflects cell loss (Lee et al., 2013)

The hyaloid membrane, surrounding the vitreous, is attached only at the optic disc, where nerves pass from the photoreceptor system to the optic nerve, at the ora serrata, and on the top side of the lens, which is the junction of photo-sensitive and non-photosensitive areas of the retina Hypotony may be defined both statistically and clinically. The statistical definition of hypotony is intraocular pressure (IOP) less than 6.5mmHg, which is more than 3 standard deviations below the mean IOP. The clinical definition of hypotony is IOP low enough to result in vision loss. The vision loss from low IOP may be caused by corneal edema, astigmatism, cystoid macular edema, or maculopathy

Normal color of optic nerve on left. Abnormal optic nerve with inferior pallor on right (Image from Clinical Decisions in Glaucoma BPEI 12) Peripapillary atrophy. Peripapillary atrophy (PPA) is a wasting or thinning of the retinal pigment epithelium (RPE) cells around the optic nerve The optic nerve supplies visual information to your brain from your eyes. Glaucoma is usually, but not always, the result of abnormally high pressure inside your eye Disorders of the optic nerve and retina are common causes of afferent visual loss in clinical neurology. The diagnosis of optic neuropathy should be considered when visual loss (affecting visual acuity, color vision, or visual field) is accompanied by abnormal optic disc appearance or a relative afferent pupillary defect (RAPD; see Chapter 17).The specific cause for an optic neuropathy often. Glaucoma is a group of diseases characterized by damage to the optic nerve that often occurs when the eye pressure is too high. This optic nerve damage can eventually result in severe vision loss. Most often the pressure is too high because the eye is able to make the fluid it needs but is unable to sufficiently drain the fluid out Specimens from the optic nerve were processed for light and electron microscopy. In ENU treated group, the optic nerve revealed reduction in the diameter of the optic nerve fibers and thinning of myelin sheath with morphological changes in the glia (astrocytes, oligodendrocytes, and microglia)

  1. Q. What are the causes of optic neuritis? The underlying cause isn't completely understood. Most experts believe that a viral infection may trigger the immune system to attack the optic nerve as if it were a foreign invader. This is the most common reason in the majority of cases I see - an autoimmune reaction
  2. A posterior vitreous detachment (PVD) is defined as the separation of the posterior hyaloid face from the neurosensory retina. At birth, the vitreous gel fills the back of the eye and normally has Jello-like consistency. As one ages, the vitreous undergoes syneresis, in which it becomes more fluid or liquid-like
  3. Glaucoma is a chronic, progressive eye disease caused by damage to the optic nerve, which leads to visual field loss. One of the major risk factors is eye pressure. An abnormality in the eye's drainage system can cause fluid to build up, leading to excessive pressure that causes damage to the optic nerve. The optic nerve is a bundle of nerve.
  4. The cause of ONH is not understood. Introduction. Optic nerve hypoplasia is the unifying feature of a spectrum condition, commonly known as septo-optic dysplasia (SOD) or DeMorsier syndrome, which includes hypopituitarism and absence of the septum pellucidum on MRI scan.

Causes . The symptoms of demyelination occur due to loss of myelin. Myelin sheaths insulate peripheral nerves as well as nerves in the brain, spinal cord, and eyes. Each eye has an optic nerve that controls vision. The myelin sheaths allow nerves to send signals efficiently Though the exact cause of normal-tension glaucoma is unknown, many researchers believe decreased blood flow to the optic nerve may be a factor. This could be caused by narrowing of blood vessels that nourish the optic nerve or constrictions of these vessels (vasospasms). Some studies also indicate that poor blood flow within the eye is. Schwartz-Matsuo syndrome is a rare cause of elevated IOP and results from an obstruction of trabecular outflow by the liberated outer segments of photoreceptors. In order to evaluate the optic nerve carefully, a clear stereoscopic view with a 78.00 or 60.00 D lens is necessary. We compare our findings to those for the fellow, normal nerve

Inflammation of the optic nerve due to ON can cause thinning. If there is no inflammation present when the doctor looks at your eye, then all he can see is thinning, the end result. An MRI will be able to show if there are lesions present and if the MRI is done with contrasting solution, active lesions will light up though their location. Excessive drinking of alcohol in both short term and long term, can have disastrous effects on the eyes. The answer to the question, can drinking alcohol cause blindness, may be tricky, but it simply says yes. Alcohol can particularly damage the optic nerve which can go to the extent of causing blindness The disc of the optic nerve is pale, the arteries are sharply narrowed, peripheral vision is characterized by concentric constriction and loss of the lower half of the field of vision. The causes are lowering of arterial pressure, anemia, disc alteration. Atrophy of the optic nerve with intoxication (poisoning with quinine) During the study, the multiple sclerosis patients demonstrated an average of 46 percent faster thinning of the ganglion cell nerve layers in their retinas compared to the healthy patients. 99% of patients with MS were found to have optic nerve lesions. Doctors were already aware that the eyes are extremely involved in multiple sclerosis
