Orbital haemorrhage and prolonged blindness: a treatable posterior optic neuropathy.

Lateral Canthotomy and Cantholysis: Emergency Management of Orbital Compartment Syndrome

“…Lateral canthotomy and cantholysis (LCC) is a simple procedure, which, when performed expeditiously, can be vision saving (1)(2)(3)(4)(5). A case report is presented, followed by a review of the relevant anatomy, pathophysiology, technique, and potential complications of the procedure.…”

Optic Nerve Trauma with Prolonged Blindness Followed by Visual-Evoked Potential

“…The mechanism responsible for amaurosis and persistent VEP is also speculative, deserving more investigation [8], However. 3 days of lasting blindness in this patient seems to be the longest documented interval of reversible optic nerve visual loss following orbital trau ma [9][10][11][12][13]15], The case illustrated the remarkable optic nerve tolerance after trau matic damage, and the valuable contribution of the VEP examination for clinical assess ment and prognosis after orbital trauma with severe visual loss.…”

“…as well as after various surgical procedures including blepharoplasy [11,12], orbital fracture repair [13][14][15], and molar fracture repair [16,17], Despite the accumulation of much clinical information, and the suggestion that pressure and compromised nutrient vessels may cause temporary or permanent blindness in a radiologically intact optic nerve, the pathogenesis is still speculative, prediction of visual recov ery uncertain, and criteria for surgical decom pression poorly defined. Such orbital optic nerve decompression produced dramatic re sults in some monocular blindness [10,11,13,15]. However, a prospective and objective assessment of the visual function by visualevoked potential (VEP) recordings prior to therapeutic decision, while justified [9.…”

“…It has been appreciated by clinicians in the field of ophthalmology and neurology after orbital and cranial trauma [1][2][3][4][5][6][7][8][9][10]. as well as after various surgical procedures including blepharoplasy [11,12], orbital fracture repair [13][14][15], and molar fracture repair [16,17], Despite the accumulation of much clinical information, and the suggestion that pressure and compromised nutrient vessels may cause temporary or permanent blindness in a radiologically intact optic nerve, the pathogenesis is still speculative, prediction of visual recov ery uncertain, and criteria for surgical decom pression poorly defined.…”

Psychological And Psychosocial Implications Of Head And Neck Cancer

“…The globe and septa are displaced forward (proptosis). Only limited by the eyelids and the length of the optic nerve 4,5 .…”
