Globe Luxation and Optic Nerve Avulsion by Dog Bite
A 9-year-old female presented to the emergency department after being attacked by her family dog. The patient was alone in the passenger seat of a parked car when the dog saw another dog, jumped into the child’s seat, and bit her left eye. The child immediately lost all vision. The left globe was luxed onto the cheek [Figure 1a] and a long segment of the optic nerve avulsed [Figure 1b]. Compute...
متن کاملAnterior chiasmal optic nerve avulsion.
In a case of traumatic avulsion of the optic nerve at the anterior chiasm, MR imaging provided highly specific images of the injury site, including the absence of the optic nerve within the optic canal and the point of transection at the anterior portion of the chiasm. This was confirmed clinically and histopathologically. MR imaging should be considered in cases of suspected chiasmal injury.
متن کاملTraumatic avulsion of the optic nerve.
Avulsion of the optic nerve is an infrequent traumatic event which results in a permanent and usually devastating loss of vision. We present two cases which highlight the salient features of partial and complete optic nerve avulsion. The clinical findings, including the results of B-scan ultrasonography, fluorescein angiography, and computed tomography (CT) are discussed. In addition, the past ...
متن کاملComplete evulsion of the globe and optic nerve.
A 17-year-old boy had an evulsion of globe and optic nerve from an automobile accident. Computed tomography showed a severed optic nerve on the injured side. A visual field defect was demonstrated in the other eye.
متن کاملPeripapillary Suprachoroidal Cavitation, Parapapillary Gamma Zone and Optic Disc Rotation Due to the Biomechanics of the Optic Nerve Dura Mater.
We thank Jonas and colleagues1 for their interest in our recent paper.2 We agree with the assertion from Jonas and colleagues1 that the biomechanics of the optic nerve dura mater, especially during eye movements, may have strong implications for various structural changes observed in highly myopic eyes. For instance, our models may be able to provide explanations about the optic disc rotation a...
