1/64. optic nerve avulsion secondary to a basketball injury.optic nerve avulsion secondary to a basketball injury is a rare complication. The patient underwent a vitrectomy for a non-clearing vitreous hemorrhage. The nerve was partially avulsed with multiple choroidal ruptures in the fovea. It was concluded that optic nerve disorders rarely occur after basketball injuries. patients with a dense vitreous hemorrhage may benefit from a vitrectomy although the vision will be limited by the optic nerve disorder.- - - - - - - - - - ranking = 1keywords = injury (Clic here for more details about this article) |
2/64. optic nerve avulsion from a golfing injury.PURPOSE: To describe a patient with optic nerve avulsion after being struck in the eye with a golf club. methods: A 10-year-old male was hit in the left eye by a golf club. The patient underwent full ophthalmoscopic evaluation and neuroimaging. RESULTS: The patient had no light perception in the left eye when first seen. Avulsion of the optic nerve with vitreous hemorrhage was apparent on examination. Computed tomographic imaging of the brain and orbits revealed no abnormalities. CONCLUSIONS: optic nerve avulsion from golf-related injury is more likely to occur when the impact site is between the globe and the orbital rim. rupture of the globe is more likely to occur with direct impact to it.- - - - - - - - - - ranking = 1keywords = injury (Clic here for more details about this article) |
3/64. Dilated pupil during endoscopic sinus surgery: what does it mean?Endoscopic sinus surgery has become the standard of care for the surgical management of chronic sinus disease. Sinus disease and its surgical treatment carry the risk of orbital complications, irrespective of the approach. Orbital complications associated with sinus surgery include nasolacrimal duct damage, extraocular muscle injury, intraorbital hemorrhage/emphysema, and direct optic nerve damage, resulting in blindness. The finding of an unequal pupil at the end of a procedure would be a cause of considerable concern, but it is most likely due to the topical contamination of the eye with a mydriatic pharmacological agent commonly used in endoscopic sinus surgery.- - - - - - - - - - ranking = 0.2keywords = injury (Clic here for more details about this article) |
4/64. Major orbital complications of endoscopic sinus surgery.BACKGROUND: The paranasal sinuses are intimately related to the orbit and consequently sinus disease or surgery may cause severe orbital complications. Complications are rare but can result in serious morbidity, the most devastating of which is severe visual loss. methods: A retrospective review was undertaken of four cases of severe orbital trauma during endoscopic sinus surgery. RESULTS: All the cases suffered medial rectus damage, one had additional injury to the inferior rectus and oblique, and two patients were blinded as a result of direct damage to the optic nerve or its blood supply. CONCLUSION: Some ophthalmic complications of endoscopic sinus surgery are highlighted, the mechanisms responsible are discussed, and recommendations for prevention, early recognition, and management are proposed.- - - - - - - - - - ranking = 0.2keywords = injury (Clic here for more details about this article) |
5/64. Indirect traumatic optic neuropathy--two case report.The aim of the study was to evaluate the treatment of indirect traumatic optic neuropathy (ITON). ITON is defined as traumatic loss of vision that occurs without external or initial ophthalmoscopic evidence of injury to the eye or its nerve. The optimal management of ITON remains controversial. history, clinical findings and treatment of two cases of ITON with high-dose corticosteroids are described. Improvement of visual acuity after treatment with high-dose corticosteroids was achieved in both cases. The treatment is evaluated in comparison to endorsed treatment modalities found in literature. We concluded that was clinically reasonable to decide to treat or not to treat the indirect optic neuropathy on an individual patient basis.- - - - - - - - - - ranking = 0.2keywords = injury (Clic here for more details about this article) |
6/64. skull-base trauma: neurosurgical perspective.Trauma to the cranial base can complicate craniofacial injuries and lead to significant neurological morbidity, related to brain and/or cranial nerve injury. The optimal management involves a multidisciplinary effort. This article provides the neurosurgeon's perspective in management of such trauma using a 5-year retrospective analysis of patients sustaining skull-base trauma. The salient features of anterior and middle skull-base (temporal bone) trauma are summarized, and the importance of frontal basilar trauma as well as brain injury is evident. With these injuries, all cranial nerves (except 9 to 12) are at risk; the olfactory nerve and the facial nerve are the first and second, respectively, to sustain injuries. This retrospective analysis provides a better understanding of cranial base trauma and its management. It emphasizes the multifaceted nature of such trauma and the need to recognize anterior skull-base complications, including cerebrospinal fluid leak and brain injury.- - - - - - - - - - ranking = 0.6keywords = injury (Clic here for more details about this article) |
7/64. Self-inflicted repetitive optic nerve injury: a case report.PURPOSE: To describe an obsessive-compulsive patient who developed blindness after self-inflicted repetitive optic nerve injury. methods: Case report. RESULTS: A myopic 46-year-old male became blind as a result of intermittent rubbing of his eyes, causing stretching of the optic nerves. Extensive ocular, neurologic and systemic work-ups were negative. Cerebral and orbital MR studies showed severe bilateral optic nerve atrophy. Psychiatric evaluation confirmed obsessive-compulsive personality. CONCLUSIONS: Self-inflicted optic nerve injury should be included in the differential diagnosis of progressive optic neuropathy in a young adult.- - - - - - - - - - ranking = 1.2keywords = injury (Clic here for more details about this article) |
8/64. Optic neuropathy resulting from indirect trauma.Minor blunt injury to the head and face may result in optic nerve contusion with secondary optic atrophy. The resulting visual loss is devastating for the individual. We report an uncommon but important complication that may result from an apparently trivial injury. Early identification and initiation of appropriate management may restore the individual's vision. Emergency physicians are often the first to see patients at risk of this complication yet there is little discussion of this injury in the emergency medicine literature.- - - - - - - - - - ranking = 0.6keywords = injury (Clic here for more details about this article) |
9/64. Axonal loss after traumatic optic neuropathy documented by optical coherence tomography.PURPOSE: To report longitudinal retinal nerve fiber layer (RNFL) thickness measurements using optical coherence tomography (OCT) in a patient with traumatic optic neuropathy. DESIGN: Observational case report. methods: A 14-year-old boy with severe optic nerve trauma had repeated OCT scans of the peripapillary retinal nerve fiber layer at 3 days, 20 days, 40 days, and 70 days after injury. RESULTS: There was gradual loss of nerve fibers as shown by the OCT color-coded map, RNFL thickness profile, and RNFL thickness measurements around the optic disk. At 70 days of follow-up, severe thinning of the RNFL was observable. CONCLUSIONS: These findings suggest that OCT is able to assess and monitor axonal loss after traumatic optic neuropathy.- - - - - - - - - - ranking = 0.2keywords = injury (Clic here for more details about this article) |
10/64. optic nerve injury in children. A prospective study of 35 patients.Thirty-five children under 15 years of age with optic nerve injury are prospectively studies for their clinical presentation, radiological findings, visual evoked potentials and outcome. Over 50% were under 10 years of age. In half of the children, injury was due to fall from a height. Fracture of the skull was recorded in a third of the patients, and optic canal fracture was seen only in three children. Visual evoked potentials (VEP) were record in 30 children and were repeated several times in first three weeks. All the patients received corticosteroids and optic canal decompression was not carried out routinely. overall spontaneous visual recovery was observed in 12 patients. Among the 30 children in whom Veps were recorded, 17 children had repeatedly absent VEP, and none of the children showed wave formation, 10 (77%) had visual recovery. Only in 5 patients an optic canal decompression was carried out several weeks after injury. This study brings out the role of VEP in children with optic nerve injury.- - - - - - - - - - ranking = 1.6keywords = injury (Clic here for more details about this article) |
