Using ImageJ to Evaluate Optic Disc Pallor in Traumatic Optic Neuropathy
PURPOSE To evaluate optic disc pallor using ImageJ in traumatic optic neuropathy (TON). METHODS This study examined unilateral TON patients. The optic disc was divided into 4 quadrants (temporal, superior, nasal, and inferior), consistent with the quadrants on optical coherence tomography (OCT) retinal nerve fiber layer (RNFL) thickness maps. Optic disc photography was performed and disc pall...

Ten patients (14 eyes) with chronic simple glaucoma are described, each with features atypical for this disease and more suggestive that each had suffered an acute ischaemic optic neuropathy. Diagnosis of an acute ischaemic optic neuropathy in these cases is important, as treatment of ocular hypertension in the contralateral 'normal' eye may prevent a similar attack. Optic nerve disease and vis...

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...
