“…Also, STIR has a lower sensitivity since only 77 (Dunker and Wiegand, 1996) 4 to 81 10 to 89% (Kapoor et al,1998) 5 of optic nerves affected within 30 days have demonstrable lesions. The MRI method used in our study will be beneficial in separating patients with optic neuritis and disc swelling from non-arteritic AION with some pain in the affected eye (Swartz et al, 1995). 11 The mean length of the optic nerve that enhanced was 13.5 mm, which is nearby the 10mm reported by 10 and 17.5mm reported by Dunker Weigand (1996) 4 using STIR.…”

STIR signal more or equal to 17mm usually occurred in patients with a longer duration between the onset of visual loss and performing the MRI (Kapoor et al, 1998).…”

“…5 NAION typically presents without pain, although some form of periocular discomfort is reported in 8-12% of affected individuals. 5,8 In contrast to patients with optic neuritis, those with NAION usually do not report pain with eye movement. The initial course may be static, with little or no fluctuation of visual level after initial loss, or progressive, with episodic, stepwise decrements, or a steady decline of vision over days to weeks before eventual stabilization.…”

Nonarteritic anterior ischaemic optic neuropathy (NAION) is the most common acute optic neuropathy in patients over the age of 50 and is the second most common cause of permanent optic nerve-related visual loss in adults after glaucoma. Patients typically present with acute, painless, unilateral loss of vision associated with a variable visual field defect, a relative afferent pupillary defect, a swollen, hyperaemic optic disc, and one or more flame-shaped peripapillary retinal haemorrhages. The pathogenesis of this condition is unknown, but it occurs primarily in patients with structurally small optic discs that have little or no cup and a variety of underlying vascular disorders that may or may not be known at the time of visual loss. There is no consistently beneficial medical or surgical treatment for the condition, but there are now animal models that allow testing of various potential therapies. About 40% of patients experience spontaneous improvement in visual acuity. Patients in whom NAION occurs in one eye have a 15-19% risk of developing a similar event in the opposite eye over the subsequent 5 years.

“…The use of steroids is controversial, with some studies showing a positive outcome. 3,22,23 The use of combined levodopa and carbidopa has been found to improve visual acuity in patients with AION. 24 In addition, significant improvement in vision has been reported with steroids and levodopa.…”
