Can you see optic neuritis on Fundoscopy?
Can you see optic neuritis on Fundoscopy?
Optic neuritis — papillitis is seen on fundoscopy. The history and MRI findings are suggestive of an underlying diagnosis of new onset multiple sclerosis.
What causes Aaion?
Arteritic AION (A-AION) is a dangerous condition caused by inflammation of arteries supplying blood to the optic nerve. The inflammation is due to a condition known as giant cell arteritis (GCA) or temporal arteritis, which causes inflammation of medium- and large-sized arteries.
How is optic neuritis different from Aion?
“Optic neuritis is an inflammatory form of optic nerve disease and can be associated with several systemic diseases, such as multiple sclerosis, whereas ischemic optic neuropathy is a vascular form of optic nerve disease and is associated with risk factors such as hypertension, diabetes, thrombotic disorders, and …
What is the difference between papilledema and optic neuritis?
In contrast to true papilledema, with AION or optic neuritis, there is a startling loss of visual acuity, but clear-cut field defects. The presence of exudates, cotton wool spots, or hemorrhages is rare in most conditions associated with optic disc swelling other than papilledema and the non-arteritic form of AION.
What is Uhthoff phenomenon?
Uhthoff’s phenomenon (also known as Uhthoff sign or Uhthoff syndrome) is described a transient worsening of neurological symptoms related to a demyelinating disorder such as multiple sclerosis when the body becomes overheated in hot weather, exercise, fever, saunas, or hot tubs.
How common is Aion?
The vast majority of cases of AION are non-arteritic. NAION affects between 2.3 and 10.3 people per 100,000 individuals per year making it the most common cause of acute optic neuropathy in patients over the age of 50. There are approximately 6000 new cases per year and Caucasians account for nearly 95% of cases.
Is Aaion bilateral?
1 Arteritic AION (AAION) is caused by giant cell arteritis, and nonarteritic AION (NAION) is the commonly occurring type and not due to giant cell arteritis. 2 Bilateral AION occurs more often in arteritic patients and bilateral simultaneous NAION is extremely rare.
Is Aion bilateral?
Is Aaion unilateral?
Manifestations include rapid onset of unilateral visual loss accompanied by decreased visual acuity (typically severe: <20/200 in over 60% of the patients), visual field (altitudinal field defect is most common) or both.
What are the stages of papilledema?
Papilledema can be graded using the Frisén scale but remains subjective, as follows: Stage 0 is a normal optic disc. Stage 1 papilledema is a C-shaped halo of disc edema with preservation of the temporal disc. Stage 2 papilledema is a circumferential halo of edema on the optic disc.
