“…For diagnosis, computed tomography (CT) is the best imaging tool for delineating optic canal fractures, and magnetic resonance imaging (MRI) can be useful for evaluating the optic nerve, especially when assessing optic nerve avulsion, recent haemorrhage resulting in an optic nerve sheath haematoma, axonal injury, or ischaemia. 4,5 Optical coherence tomography (OCT) and scanning laser polarimetry (GDx) have been shown to facilitate the diagnosis and management of glaucoma by detecting the slow decrease in retinal nerve fibre layer (RNFL) thickness that occurs during the course of glaucomatous optic neuropathy. [6][7][8] Previous studies have also shown that changes in the optic disc and RNFL can be measured with OCT and GDx after acute injury to the optic nerve.…”
