Can optic neuritis cause lazy eye?

What is the medical term meaning inflammation of the optic nerve?

Inflammation of the optic nerve is called Optic neuritis. Optic neuritis can be caused by several factors such as hereditary disorders, toxic exposure, metabolic disorders such as diabetes or autoimmune disorders such as multiple sclerosis. There is usually no visual evidence of optic neuritis. Pain upon eye movement is a clinical sign of such. Inflammation of the optic nerve is called Optic neuritis.

Optic neuritis?

DefinitionOptic neuritis is inflammation of the optic nerve. It may cause sudden, reduced vision in the affected eye.Alternative NamesRetro-orbital neuritis Causes, incidence, and risk factorsThe cause of optic neuritis is unknown.Sudden inflammation of the nerve connecting the eye and the brain (optic nerve) can injure the insulation (myelin sheath) surrounding each nerve fiber, causing the nerve to swell.Causes of the inflammation can include:Autoimmune diseases (systemic lupus erythematosus, sarcoidosis, Behcet disease, autoimmune optic neuritis)Infections (tuberculosis, syphilis, Lyme disease, meningitis, viral encephalitis, and post-infectious measles, rubella, chickenpox, herpes zoster, mumps, and Mycoplasma pneumonia or other common upper respiratory tract infections)Multiple sclerosis (most often in adults, but also in children)Toxicity from drugs such as methanol or ethambutolVitamin B-12 deficiencyRisk factors are related to the particular cause.SymptomsLoss of visionin one eye, over the course of an hour or a few hoursChanges in the way the pupil reacts to bright lightLoss of color visionPain when you move the eyeSigns and testsA complete medical examination can help rule out related diseases. Tests may include the following:Color vision testingMRI of the brain including special images of the optic nerveVisual acuity testingVisualization of the optic disc by indirect ophthalmoscopyTreatmentVision often returns to normal within 2 - 3 weeks with no treatment.Corticosteroids given through a vein (IV) may speed up recovery. Higher doses should be used cautiously, as they can have serious side effects.Further tests may be needed to determine the cause of the neuritis. The condition causing the problem can then be treated.Expectations (prognosis)People who have optic neuritis without a disease such as multiple sclerosis have a good chance of recovery.Optic neuritis caused by multiple sclerosis or other autoimmune diseases such as systemic lupus erythematosus has a poorer outlook, although vision in the affected eye may still return to normal.ComplicationsBody-wide side effects from corticosteroidsVision lossAbout 20% of patients with a first episode of optic neuritis will develop myelin sheath inflammation at other sites or will develop multiple sclerosis.Calling your health care providerCall your health care provider immediately if you have a sudden loss of vision in one eye.If you have optic neuritis, call your health care provider if:Your vision decreasesYou develop pain in the eyeYour symptoms do not improve with treatmentReferencesGermann CA, Baumann MR, Hamzavi S.

What could cause Optic nerve enlargement in children under 5?

The optic nerve head is the only part visible through the front of the eye. This can falsely appear enlarged in shortsighted people. It may actually be swollen due to many possible reasons. Optic neuritis: inflammation of the nerve itself, often seen in multiple sclerosis. Ischaemia: starvation of blood to the nerve and/or retina (due to a blockage). Papilloedema: this is congestion of the nerve head, usually as a result of raised pressure inside the skull. This may be due to head injury, infection i.e. meningitis, chronic glaucoma, or a tumour, as well as a great many other rare causes.

Where does the optic nerve leave the eye?

The optic nerve exits the retina at the optic disc, otherwise known as the "blind spot".

Parasympathetic fibers of which nerve innervate smooth muscles of the lens of the eye - the eye muscles that cause the eye to bulge to accommodate close vision?

Optic

What does the myelin do in the eye?

Demyelination in the brain and its effects on the optic nerve can cause objects directly ahead to be blurred in one eye, and eventually lead to blindness in that eye.

Is there an optic nerve for each eye?

What does it mean when your eye sockets hurt?

It may be possible that you have Optical Neuritis which is the swelling of the optic nerve. Seeing your eye doctor is important to rule this out as Optical Neuritis can be linked to MS and other disease. If it is a one time event, don't spend much concern with it as it may be associated with a headache or eye strain.

What is the function of the optic disk in the eye?

Optic disc:The optic disc is also called the blind spot. There are no receptors in this part of the retina. This is where all of the axons of the ganglion cells(last neurons before optic nerve) exit the retina to form the optic nerve.
