1/6. Bone from an orbital floor fracture causing an intraocular foreign body.PURPOSE: To describe the ophthalmoscopic and radiologic findings of a patient who sustained blunt orbital trauma. A piece of bone from the fractured orbital wall caused an intraocular foreign body. DESIGN: Case report. methods: An 18-year-old man underwent full ophthalmoscopic examination 1 week after sustaining blunt ocular trauma to the right eye while playing basketball. B-scan ultrasonography and computed tomography of the orbits were also performed. RESULTS: visual acuity, intraocular pressure, and anterior segment examination were normal. Funduscopic examination revealed a fragment of bone that had penetrated the sclera, choroid, and retina. A hole in the sclera was visible. No treatment was performed. Three months later, the patient had no ocular complaints or complications as a result of this injury. CONCLUSION: Bone from a patient's orbit may cause an intraocular foreign body that may be followed conservatively in certain circumstances.- - - - - - - - - - ranking = 1keywords = floor (Clic here for more details about this article) |
2/6. Compressive optic neuropathy after use of oxidized regenerated cellulose in orbital surgery: review of complications, prophylaxis, and treatment.PURPOSE: We report 2 cases of compressive optic neuropathy after use of oxidized regenerated cellulose (ORC) in orbital surgery. To our knowledge, no complications have been reported previously after use of this material in orbital surgery. We also review the complications related to its retention at operative sites outside the orbit and recommend precautions to avoid them. DESIGN: Retrospective interventional case reports. PARTICIPANTS: Two patients with compressive optic neuropathy after use of ORC in orbital surgery. methods: case reports from 2 different clinics and review of the English scientific literature. MAIN OUTCOME MEASURES: Best-corrected visual acuity, extraocular motility, proptosis, and chemosis. RESULTS: One patient underwent orbital exploration and biopsy of an orbital tumor, and the second had repair of an orbital floor fracture. Postoperatively, both presented with chemosis, ophthalmoplegia, and progressive loss of vision. Orbital imaging revealed a retrobulbar soft-tissue density compatible with hematoma. Repeat orbital exploration revealed the soft-tissue mass to be swollen ORC. CONCLUSIONS: Retained intraorbital ORC may cause a compartment syndrome and should be suspected in postoperative patients with orbital symptoms. When ORC is used around the optic nerve, it should be removed after hemostasis is achieved.- - - - - - - - - - ranking = 0.25keywords = floor (Clic here for more details about this article) |
3/6. Oculocerebral perforating trauma by foreign objects: diagnosis and surgery.Two unusual cases of perforating oculocerebral trauma by foreign bodies treated surgically are reported. Both were caused by industrial accidents. In the first a nail shot from a nail gun ricocheted off the target and crossed the right eyeball and the posterior wall of the orbit, lodging in the homolateral temporal lobe. In the second case a metal fragment expelled by an agricultural machine penetrated the left maxillary sinus, crossed the floor of the orbit, the eyeball and the roof of the orbit and lodged in the homolateral frontal lobe. After accurate neuroradiological examination the patients were operated using simultaneous transcranial and transorbital access. In our opinion this is the only approach which can minimize the risk of infection which is so dangerous in this type of trauma. The functional and aesthetic results, which were very satisfactory in both cases, seem to confirm the correctness of this approach.- - - - - - - - - - ranking = 0.25keywords = floor (Clic here for more details about this article) |
4/6. An unusual case of bull gore injury.An unusual and hitherto unreported presentation of a bull gore injury sustained during harvest festival celebrations is described. The patient was seen with the metal horn cover complete with decorative ribbons impacted in his orbit. The injury had caused a blowout fracture of the orbital floor, and at surgery the globe was retrieved from the maxillary antrum. The development of optic atrophy precluded useful vision in the injured eye.- - - - - - - - - - ranking = 0.25keywords = floor (Clic here for more details about this article) |
5/6. Finger in his eye.A 21-year-old soldier sustained a schrapnel blast injury during an accident with a mortar fuse. Surgical repair included the use of one of his reconstructed metacarpal bones to repair the orbital floor. The remainder of the orbital floor was repaired using maxillary bone. It proved an excellent method of repairing this patient's orbital floor.- - - - - - - - - - ranking = 0.75keywords = floor (Clic here for more details about this article) |
6/6. A wooden orbital foreign body.A case is reported in which a patient presented, 18 months after initial injury, with a progressive proptosis of the left eye. x-rays did not reveal a foreign body but a fracture of the lateral orbital wall and an area of soft tissue density were seen on the CT scan. Exploration of the orbit revealed a 2 cm wooden fragment in the floor of the orbit.- - - - - - - - - - ranking = 0.25keywords = floor (Clic here for more details about this article) |
