Traumatic ischaemic optic neuropathy.
Persistent profound visual loss following contusion of the globe or ocular adnexae has been well documented, the visual loss being attributed to haemorrhage into, or contusion of, the optic nerve, or to interference with the blood supply of the eye. The patient described below presented after a contusion of the eye and orbit, with the clinical picture of ischaemic optic neuropathy presumably re...
متن کاملIndirect traumatic optic neuropathy
Indirect traumatic optic neuropathy (ITON) refers to optic nerve injury resulting from impact remote to the optic nerve. The mechanism of injury is not understood, and there are no confirmed protocols for prevention, mitigation or treatment. Most data concerning this condition comes from case series of civilian patients suffering blunt injury, such as from sports- or motor vehicle-related concu...
متن کاملTraumatic optic neuropathy.
Introduction: Traumatic optic nerve damage after craniofacial injury was first described by Hippocrates.1 Although the natural history of traumatic optic neuropathy is unknown, recent studies suggest that high dose steroids and, even surgical decompression of the optic canal or the nerve sheath (in cases of nerve sheath hematoma) may restore vision in selected patients.2-8 The commonest cause o...
متن کاملMorphological and functional changes of the optic nerve following traumatic optic nerve injuries in rabbits.
The aim of the present study was to investigate the morphological changes of the optic nerve following traumatic injuries and decompression at different times after injury, and to observe the changes of the visually evoked potentials, to identify the relevant associations between surgical opportunity and the clinical effect of traumatic optic nerve injuries. Rabbits were chosen as the animal mo...
متن کاملHyperintense Optic Nerve due to Diffusion Restriction: Diffusion-Weighted Imaging in Traumatic Optic Neuropathy.
BACKGROUND AND PURPOSE Abnormal signal intensity of the optic nerve due to diffusion restriction may be seen in traumatic optic neuropathy. In addition to evaluating optic nerve hyperintensity on diffusion-weighted imaging, we compared the group differences of ADC values between the injured and uninjured contralateral nerve and identified the relation between measured ADC values and admission v...
