1/9. Bilateral orbital emphysema from compressed air injury.PURPOSE: To describe a patient who developed bilateral subconjunctival and orbital emphysema after an automobile tire explosion. METHOD: Case report. RESULTS: A 60-year-old man sustained bilateral ocular injury after a tire explosion. Ophthalmic examination disclosed bilateral subconjunctival air, with no visible conjunctival laceration. Computed tomography showed orbital emphysema, with no evidence of orbital fracture. Follow-up examination 2 weeks after the injury disclosed resolution of the subconjunctival air. Best-corrected visual acuity in the right eye was decreased after the explosion but improved to the baseline level of 20/40 2 weeks after the injury. CONCLUSION: Subconjunctival and orbital emphysema can occur from high-pressure air injury in the absence of an obvious entry site.- - - - - - - - - - ranking = 1keywords = emphysema (Clic here for more details about this article) |
2/9. Large subconjunctival emphysema causing diplopia and lagophthalmos.PURPOSE: To describe a patient who developed diplopia, lagophthalmos and exposure keratopathy due to a large subconjunctival emphysema. methods: A 24-year-old man sustained an injury in his left eye from a compressed air hose. The patient complained of pain and diplopia. He underwent slit-lamp examination, funduscopy and computed tomography. RESULTS: Ophthalmic examination revealed a decrease in vision in the left eye to 0.5, a conjunctival laceration adjacent to the medial limbus, subconjunctival hemorrhage, a large subconjunctival emphysema, lagophthalmos, hypertropia and superficial punctate keratopathy. The posterior pole was intact as were the orbital bones. Two weeks after the injury the conjunctival emphysema, diplopia, lagophthalmos and superficial keratopathy resolved, and visual acuity improved to 1. CONCLUSIONS: Large subconjunctival emphysema can result in diplopia, lagophthalmos and exposure keratopathy.- - - - - - - - - - ranking = 1.1428571428571keywords = emphysema (Clic here for more details about this article) |
3/9. Tension pneumoorbitus.Posttraumatic tension orbitus developed in a young man causing subconjunctival emphysema and proptosis. Intraocular pressures were monitored as a means of indirectly measuring intraorbital pressure. The patient was serially examined for evidence of compressive optic neuropathy. Because of the possibility of orbital pressure increasing several hours from the time of injury, we recommend monitoring of these patients through intraocular pressure measurement and evaluation of the optic nerve for evidence of compression. Our findings, however, do support previous documentation that the intraocular pressure rise following orbital trauma with orbital emphysema is usually not of sufficient severity or duration to result in visual compromise.- - - - - - - - - - ranking = 0.28571428571429keywords = emphysema (Clic here for more details about this article) |
4/9. A rare mechanism of orbital emphysema.Orbital emphysema is usually described in association with fractures of the paranasal sinuses involving the orbit. We describe a rare form of orbital emphysema caused by high-pressure subconjunctival air injection from an air tube used in a garage, without apparent damage to the orbital walls.- - - - - - - - - - ranking = 0.85714285714286keywords = emphysema (Clic here for more details about this article) |
5/9. Oedipism reviewed: a case of bilateral ocular self-mutilation.A 26-year-old Negro male schizophrenic is described with severe bilateral orbital injuries following attempted self-enucleation. Owing to his psychosis there was difficulty in obtaining a visual acuity and in establishing the cause of his fixed, dilated pupils. ACT scan showed bilateral orbital oedema, with surgical emphysema and haemorrhage. The visual evoked potential (VEP) was present in the right eye but absent in the left. High doses of systemic steroids effected rapid resolution of the orbital swelling and recovery of the vision in the right eye. The effects of self-inflicted injury to the orbital content and the value of sophisticated investigation in this unusual case are discussed.- - - - - - - - - - ranking = 0.14285714285714keywords = emphysema (Clic here for more details about this article) |
6/9. Downward displacement of the eye resulting from orbital emphysema (case report).A case is reported of unusual downward displacement of the eye, occurring in a patient with fractures of the orbital floor and rim. On the basis of the clinical, roentgenological and computerized tomographic scan findings this is interpreted as resulting from a subperiosteal pneumatocoele above the eye ball.- - - - - - - - - - ranking = 0.57142857142857keywords = emphysema (Clic here for more details about this article) |
7/9. Orbital emphysema complicated by acute central retinal artery occlusion: case report and treatment.Orbital emphysema is a well-known clinical entity that has been considered benign and requiring no treatment. A case of marked orbital emphysema with simultaneous central retinal artery occlusion is described. The prompt relief of this occlusion following aspiration of air from the orbit suggests that orbital emphysema is an unreported cause of central retinal artery occlusion.- - - - - - - - - - ranking = 1keywords = emphysema (Clic here for more details about this article) |
8/9. A case of orbital emphysema as an ocular emergency.Orbital emphysema is radiologically apparent in 50% of cases of orbital fractures, but it is generally a benign, self-limited condition. However, visual loss may occur if a fracture produces orbital compression via a ball-valve effect, allowing air to enter but not leave the orbit. A case of compressive orbital emphysema complicated by ischemic optic neuropathy is reported. Intraorbital needle aspiration relieved the compression with improvement of visual acuity and normalization of intraocular pressure.- - - - - - - - - - ranking = 0.85714285714286keywords = emphysema (Clic here for more details about this article) |
9/9. Isolated medial orbital blow-out fracture with medial rectus entrapment.PURPOSE: The authors report on three cases of isolated medial orbital blow-out fracture with medial rectus entrapment which occurred in black males. Only a few similar cases have been reported in the literature. methods: The diagnosis was established with the help of tomography and CT scan of the orbit. RESULTS: The diagnosis could be expected from the clinical signs occurring after blow-out trauma mechanisms: eyelid emphysema, nasal subconjunctival haemorrhage, motility disturbance, enophthalmos. CONCLUSION: An ethnic anatomic hypothesis could explain the predominance of this fracture in blacks. This fracture often remains undiagnosed. The diagnosis was based on axial and especially coronal CT scan of the orbit. The physician should be alerted by some clinical signs that justify these radiographic techniques.- - - - - - - - - - ranking = 0.14285714285714keywords = emphysema (Clic here for more details about this article) |
