Identification of Optic Nerve Swelling
Using Point-of-Care Ocular Ultrasound in Children.
Follow-up orbital MRI after four months showed decreased right optic nerve swelling with disappeared contrast-enhancement, suggesting chronic stage of optic neuritis (Figure 3c, d).
(c, d) Follow-up orbital magnetic resonance imaging after four months showed decreased right optic nerve swelling with disappeared contrast-enhancement, suggesting chronic stage of optic neuritis.
It is widely acknowledged that hemorrhage inside the meningeal sheath, optic nerve swelling
, and necrosis secondary to decreased blood flow could be the main pathology of TON.
(1) Optic nerve swelling
from etiology other than IICP is known as optic disc edema.
MS is the major cause of acute optic neuritis in adults, (23) in two-thirds of cases retrobulbar and in one third papillitis, possibly with mild optic nerve swelling
. Using the life-table method, the probability of developing MS may rise to 78% 15 years after an episode of optic neuritis.
Dilated fundus exam revealed marked bilateral optic nerve swelling
. A thin peripapillary submacular hemorrhage of less than 300 micrometer in diameter was present in OS.
Optic nerve swelling
or papilloedema can occur if intracranial pressure is raised following a brain injury (Figure 2).
The posterior segment of both eyes was normal and the fundus showed no signs of optic nerve swelling
or retinal hemorrhages.
