The researchers also measured the eye socket of the skull and the opening to the optic canal, where the optic nerve would have been located.
The human orbit is related to the middle cranial fossa through various canals and openings, such as optic canal and superior orbital fissure.
Orbital periosteum was kept intact, when all the bone was cleared off the optic canal and underlying optic nerve sheath was clearly visible, the sheath was incised.
In the parasellar region, Anterior Clinoid Process (ACP) with its supporting structures like Optic Strut (OS), medial part of lesser wing of the sphenoid and roof of the optic canal are certain bony landmarks related to important elements like the cavernous sinus, Internal Carotid Artery (ICA), Optic Nerve (ON) and the pituitary gland.
The most common site of indirect TON is the part of the optic nerve situated in the optic canal, followed by the intracranial part of the optic nerve and chiasm (2).
We performed detailed eye examination before and after HSCT, including orbital three-dimensional computer tomography (CT) scan to measure the optic canal diameters, RetCam III fundus examination, flash visual evoked potential (FVEP), and flash electroretinogram (FERG) using the standard FVEP protocols recommended by the International Standard EEG 10-20 System (ISCEV) (Roland Inc., German).
Conventionally, indirect TON is managed by oral and/or intravenous high or megadose methyl prednisolone, surgical decompression of optic canal, combined therapy, or just observation.
Some of these injuries can extend as far as the cerebellum and brain stem [11, 12] depending on the route of access, such as the orbital walls, optic canal, or superior orbital fissure and foreign body trajectory [13, 14].
The multidetector computed tomography (MDCT) of the paranasal sinuses illustrated a nonenhanced soft tissue density lesion in the right sphenoid sinus and no visualization of the superior wall of the right sphenoid sinus, adjacent to the right optic canal, as well as a wall that became thinner by either pressure effect of right sphenoid lesion or bony destruction (Figure 2).
[2] The orbital apex is defined as the region between the posterior ethmoidal foramen and the openings of the optic canal and the superior orbital fissure.
Since brimonidine exerts neuroprotective effects against glutamate excitotoxicity-induced oxidative stress [72] and oligodendrocytes in the optic nerve are vulnerable to glutamate neurotoxicity [82], it would be interesting to investigate if brimonidine can indeed prevent demyelination if administered via a different route, such as systemically or directly into the optic canal.
For these 20 patients 9 with obvious facture in the optic canal or sharp decline of vision received surgical decompression of the optic canal.
