1/34. hyphema caused by a metallic intraocular foreign body during magnetic resonance imaging.PURPOSE: To report a 63-year-old man with a retained intraocular foreign body who developed a hyphema during magnetic resonance imaging (MRI) of the brain. methods: Case report and review of the current literature on ocular injury caused by intraocular foreign bodies when subjected to an electromagnetic field. RESULTS: Our patient underwent a brain MRI, and the intraocular foreign body caused a hyphema and increased intraocular pressure. The presence and location of the intraocular foreign body were determined by computed tomography (CT). CONCLUSION: magnetic resonance imaging can cause serious ocular injury in patients with ferromagnetic intraocular foreign bodies. This case demonstrates the importance of obtaining an occupational history, and, when indicated, a skull x-ray or CT to rule out intraocular foreign body before an MRI study.- - - - - - - - - - ranking = 1keywords = metal (Clic here for more details about this article) |
2/34. Exogenous candida endophthalmitis in a hop grower--a case report.A case is reported of exogenous candida endophthalmitis after ocular injury with a metal wire used for hop growing. A detailed description of treatment with vitrectomy and intravitreal amphotericin b injection is presented. On the basis of our experience, in such cases it is advisable to perform vitrectomy with amphotericin b intravitreal injection and silicone oil tamponade to prevent retinal detachment.- - - - - - - - - - ranking = 0.25keywords = metal (Clic here for more details about this article) |
3/34. Retinal fixation of traumatic retinal detachment with metallic tacks: a case report with 10 years' follow-up.BACKGROUND: Retinal rupture and detachment caused by traumatic ocular perforation has a poor prognosis without extensive repair procedures. The authors describe the phases of treatment of a complex injury in a 21-year-old man with a traumatic retinal rupture in whom metallic tacks were used for retinal fixation. The report does not include histopathology. methods: Observational case report and literature review. The outcome of a 10-year follow-up is evaluated at the latest visit by determining the visual acuity (VA) and by observing the state of retina and tacks. RESULTS: A traumatic retinal rupture with detachment was treated with titanium tacks for retinal fixation. By inserting a total of 13 metallic tacks for the repair of a temporal postequatorial retinal rupture and adjacent retinal detachment a successful outcome was achieved. Two additional operations were performed to reattach the retina of nasal hemisphere in the same eye. One dislodged tack was removed at the final operation. Ten years later, at the last intervention, VA was 12/20 in the injured eye. The retina was completely attached, and the remaining 12 tacks were in place, although six of them were partially pushed up by an encircling band. Proliferative vitreoretinopathy (PVR) was absent, and a relatively narrow circumferential zone of scar tissue adjacent to the row of tacks was visible. The patient occasionally experienced glare in the affected eye, but was otherwise symptom-free. CONCLUSION: Reports of long-term experiences with mechanical retinal refixation with metallic tacks are scarce. Especially in extended use, the tacks are claimed to cause several complications, including PVR. Although modern ophthalmic surgery offers a variety of methods for retinal reattachment, the complexity of the damage caused by trauma may lead to a dead end in refixation attempts. Nevertheless, retinal tacks may represent an adjunctive remedy in complex retinal detachment cases.- - - - - - - - - - ranking = 1.75keywords = metal (Clic here for more details about this article) |
4/34. X-ray turns a blind eye to ferrous metal.The case is reported of a 31-year-old man with a retained metallic intraocular foreign body (IOFB) in the left eye who underwent magnetic resonance imaging (MRI) for investigation of a subsequent unrelated brachial plexus injury Despite the patient providing good history of IOFB, the decision to proceed with MRI was based on screening orbit X-ray which was reported as normal. A review of published reports regarding screening recommendations for MRI for patients with IOFB is provided. A minimum recommendation is for prescreening questionnaire; belief of the patient history is critical. If there is any doubt after history and examination by an ophthalmologist, then computed tomography imaging of the orbits is recommended.Whether screening by plain X-ray imaging is worthwhile is debatable as the sensitivity and specificity of this modality is poor.- - - - - - - - - - ranking = 1.25keywords = metal (Clic here for more details about this article) |
5/34. A metallic foreign body presenting in the anterior chamber angle.PURPOSE: This article describes a case in which a patient presented with a previously undetected metallic foreign body in the anterior chamber angle. methods AND RESULTS: A 42-year-old Hispanic man presented with a 5-day history of foreign-body sensation and redness in his left eye. He had been using a hand saw without safety glasses 2 days before the onset of his initial symptoms. Physical examination revealed a metallic foreign body embedded in the inferior angle of his left eye. Surgical removal of the foreign body was performed, and the patient remains well 1 year after surgery. CONCLUSIONS: All physicians should maintain a high degree of clinical suspicion for intraocular foreign bodies when presented with a patient who may have sustained ocular trauma. All eye-care providers need to emphasize the need for proper eye protection to patients who engage in high risk activities that may lead to penetrating ocular trauma.- - - - - - - - - - ranking = 1.5keywords = metal (Clic here for more details about this article) |
6/34. Corneal laceration and intraocular foreign body in a post-LASIK eye.PURPOSE: To describe a case of full-thickness corneal laceration and intraocular foreign body in an eye that underwent laser-assisted in situ keratomileusis (LASIK). methods: A 43-year-old man underwent uneventful bilateral LASIK. Seventeen months after LASIK, the patient suffered penetrating trauma to the right eye while hammering metal without safety glasses. Examination on the night of the injury showed an uncorrected visual acuity of 20/30 in the right eye. Slit-lamp biomicroscopy showed a 2.4-mm full-thickness peripheral corneal laceration at the 11-o'clock position extending over the edge of the previous LASIK flap and a foreign body partially embedded in the superior iris. He was started on prophylactic topical and intravenous antibiotics. Under general anesthesia, the corneal laceration was repaired, and the intraocular foreign body was removed without any complications. RESULTS: At the follow-up visit 9 months after the surgery, the uncorrected visual acuity was 20/25 in the right eye. On slit-lamp examination, the corneal sutures and the well-positioned LASIK flap were in place. CONCLUSION: Penetrating trauma of the cornea did not lead to flap-related complications in this post-LASIK eye. Repair of the corneal laceration and removal of the intraocular foreign body after LASIK were managed without complications. Care must be taken to try not to manipulate or lift the LASIK flap during corneal laceration repair.- - - - - - - - - - ranking = 0.25keywords = metal (Clic here for more details about this article) |

9/34. Posterior capsule tear caused by misalignment within a silicone irrigation/aspiration tip.We describe a surgical complication with the Alcon silicone irrigation/aspiration (I/A) tip. In 2 consecutive cases, the posterior capsule was torn because of a misalignment between the inner metallic shaft and the hole in the silicone I/A tip. To achieve the protective benefits of this device, the surgeon must visually confirm proper alignment of the outer silicone and inner metallic portion of the tip.- - - - - - - - - - ranking = 0.5keywords = metal (Clic here for more details about this article) |
10/34. Intravitreal triamcinolone in cystoid macular edema due to uveitis and repeated surgery after a penetrating trauma.PURPOSE: To test the effectiveness of intravitreal triamcinolone acetonide in treating macular edema due to multiple vitreoretinal surgical procedures and uveitis after a penetrating trauma with metallic foreign body retention in a 37-year-old man. methods: The patient received two intravitreal injections of triamcinolone acetonide-2 mg/0.05 mL and 4 mg/0.1 ml(-1) month apart. The 6-month follow-up included best-corrected visual acuity (BCVA) measurement and optical coherence tomography evaluation. RESULTS: After the first injection (2 mg) the foveal thickness (685 microm, as compared to a normal value of <165 microm) and the BCVA (20/200) remained unchanged with respect to the preinjection values; 1 week after the second injection (4 mg), the foveal thickness went down to 130 microm and the BCVA improved (20/80). Such results were unchanged at the 6-month control. No complications occurred. CONCLUSIONS: A 2 mg dose of triamcinolone acetonide did not improve the anatomic and functional status of the macula. A 4 mg dose markedly improved BCVA and reduced the macular thickness in this case of macular edema.- - - - - - - - - - ranking = 0.25keywords = metal (Clic here for more details about this article) |
