1/227. siderosis bulbi resulting from an intralenticular foreign body.PURPOSE: To report a case of siderosis bulbi that resulted from a small intralenticular foreign body. METHOD: Case report. RESULTS: A 36-year-old man with normal visual acuity and a peripheral intralenticular iron foreign body in the left eye was treated conservatively. Nine weeks after the injury, he had ocular signs of siderosis bulbi, with changes in the electroretinogram. A clear lens aspiration with removal of the foreign body was performed. After removal of the iron foreign body, no progression or regression of the ocular signs of siderosis bulbi has occurred, and the electroretinogram has not changed over a 2-year period. CONCLUSIONS: Even in the presence of good vision, a patient with an intralenticular ferrous foreign body should be followed closely, and the foreign body should be removed before irreversible siderosis bulbi occurs.- - - - - - - - - - ranking = 1keywords = body (Clic here for more details about this article) |
2/227. A case of an intraocular foreign body due to graphite pencil lead complicated by endophthalmitis.We report a case of an 8-year-old boy who presented with an intraocular foreign body composed of graphite pencil lead. The patient had been accidentally poked in the right eye with a graphite pencil. Primary care consisted of corneal suturing and lens extraction. Two pieces of the pencil lead remained in the vitreous cavity following surgery, and 2 days later the patient developed endophthalmitis. Pars plana vitrectomy was performed immediately and the intraocular foreign bodies were removed through the scleral wound. Cultures of the vitreous fluid revealed no bacterial organisms. X-ray fluoroscopic analysis of the vitreous detected 1 ppm of aluminum (a constituent of the pencil lead). Although the clinical presentation indicated probable bacterial endophthalmitis, the detection of elemental aluminum within the vitreous cavity also suggested the possibility of further retinal toxicity due to some dissolving of the pencil lead.- - - - - - - - - - ranking = 0.5keywords = body (Clic here for more details about this article) |
3/227. Eyelid foreign body mimics an intraocular foreign body on plain orbital radiography.Localization of a foreign body detected on plain orbital radiography may be achieved by comparing radiographs taken with the eyes in upgaze and downgaze. Movement of the foreign body with ocular rotation is considered to indicate localization either within the globe itself or within the soft tissues of the orbit closely related to the globe. A case is reported that demonstrates that this radiologic feature may also occur when a foreign body is located within an eyelid because the position of the eyelids also changes on vertical eye movements. An eyelid foreign body may therefore mimic an intraocular foreign body on plain orbital radiography.- - - - - - - - - - ranking = 1.3keywords = body (Clic here for more details about this article) |
4/227. The role of ultrasound biomicroscopy in ocular trauma.PURPOSE: To demonstrate the usefulness of ultrasound biomicroscopy (UBM) in detecting and localizing small ocular foreign bodies. methods: This is a retrospective study of the records of 555 consecutive patients evaluated by UBM by the Visual physiology Unit of the wills Eye Hospital from August 1994 to November 1997. RESULTS: In 9 patients, a foreign body was identified. In 6 patients, the history suggested the presence of a foreign body, but one could not be detected by clinical examination. In 2 patients, the referring physicians requested UBM to determine whether or how deep a known foreign body had penetrated the globe. In 1 patient, the foreign body was not suspected clinically. In regard to other diagnostic techniques, CT failed to identify the foreign body in 1 patient. In another, contact B-scan ultrasonography failed. In a third, both CT and contact B-scan ultrasonography failed. The foreign body was intracorneal in 2 eyes, subconjunctival in 2, intrascleral in 3, and intraocular in 2. Six were nonmetallic. Two were metallic. In one case, the foreign body was lost and its composition is unknown. In 5 cases, the UBM findings altered the patient's management. CONCLUSIONS: UBM is a valuable adjunct in the evaluation of small, anteriorly located foreign body that may not be detectable by other methods. UBM may be especially useful for finding nonmetallic foreign bodies.- - - - - - - - - - ranking = 0.8keywords = body (Clic here for more details about this article) |
5/227. The importance of CT scans in planning the removal of orbital-frontal lobe foreign bodies.PURPOSE: To describe the management of foreign bodies in the orbit and frontal lobe. methods: Reports of two cases. RESULTS: Both patients underwent successful removal of an orbital-cerebral foreign body by anterior orbitotomy. CONCLUSION: Computed tomography was useful to confirm preoperatively that the foreign body was not adjacent to cerebral blood vessels and to monitor postoperatively for cerebral hemorrhage. A team approach is necessary in the management of orbital-frontal lobe foreign bodies.- - - - - - - - - - ranking = 0.2keywords = body (Clic here for more details about this article) |
6/227. Reversible retinal toxicity associated with retained intravitreal copper foreign body in the absence of intraocular inflammation.PURPOSE: To report on a patient who developed retinal toxicity from an intraocular copper foreign body in the absence of any signs of chalcosis or inflammation. METHOD: Case report. RESULT: Removal of the copper foreign body resulted in electroretinographic improvement and the patient has retained good vision. CONCLUSION: Retinal toxicity from intraocular copper can be subclinical and such foreign bodies should be removed. Removal of the foreign body can be associated with at least partial reversal of retinal toxicity.- - - - - - - - - - ranking = 0.7keywords = body (Clic here for more details about this article) |
7/227. Orbitocranial injury caused by wood.A rare case of a patient with orbitocranial injury by a wooden foreign body is reported. Penetrating periorbital wound by a wooden stick with entry site at the right upper eyelid was related to the invasion into the temporal lobe. Fortunately, the anterior and posterior segments of eye were unharmed, but right ocular motility was markedly restricted mechanically in all directions. Forced duction test was strong positive, especially the dextroversion of the right eye. Computed tomography scan showed a well-delineated low density from the orbital wall into the temporal lobe. The wooden foreign body was subsequently removed from the orbit and the temporal lobe, through the neurosurgical frontotemporal approach. After the wooden foreign body was removed, the ocular movement of the right eye fully recovered without any intracranial or ocular complications.- - - - - - - - - - ranking = 0.3keywords = body (Clic here for more details about this article) |
8/227. 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 = 0.8keywords = body (Clic here for more details about this article) |
9/227. Surgical treatment of penetrating orbito-cranial injuries. Case report.Penetrating orbital injuries are not frequent but neither are they rare. The various diagnostic and therapeutic problems are related to the nature of the penetrating object, its velocity, shape and size as well as the possibility that it may be partially or wholly retained within the orbit. The authors present another case with unusual characteristics and discuss the strategies available for the best possible treatment of this traumatic pathology in the light of the published data. The patient in this case was a young man involved in a road accident who presented orbito-cerebral penetration caused by a metal rod with a protective plastic cap. Following the accident, the plastic cap (2.5x2 cm) was partially retained in the orbit. At initial clinical examination, damage appeared to be exclusively ophthalmological. Subsequent CT scan demonstrated the degree of intracerebral involvement. The damaged cerebral tissue was removed together with bone fragments via a bifrontal craniotomy, the foreign body was extracted and the dura repaired. Postoperative recovery was normal and there were no neuro-ophthalmological deficits at long-term clinical assessment. Orbito-cranial penetration, which is generally associated with violent injuries caused by high-velocity missiles, may not be suspected in traumas produced by low-velocity objects. Diagnostic orientation largely depends on precise knowledge of the traumatic event and the object responsible. When penetration is suspected and/or the object responsible is inadequately identified, a CT scan is indicated. The type of procedure to adopt for extraction, depends on the size and nature of the retained object. Although the possibility of non-surgical extraction has been described, surgical removal is the safest form of treatment in cases with extensive laceration and brain contusion.- - - - - - - - - - ranking = 0.1keywords = body (Clic here for more details about this article) |
10/227. Recurrent fungal keratitis and endophthalmitis.PURPOSE: To report a case of recurrent fungal sclerokeratitis and endophthalmitis with a very successful outcome due to aggressive combined surgical and medical therapy. To discuss the management of this potentially devastating infection. methods: A 65-year-old man presented with 6 months of left eye redness and irritation after injury from organic matter propelled from an airboat. Initially, he had been treated with foreign body removal, antibiotics, and steroids. He was diagnosed with reactive sclerokeratitis at presentation and was treated with steroids. However, when he did not improve, cultures were obtained and acremonium species filamentous fungi was identified. Despite treatment with appropriate topical and systemic antifungals, his fungal sclerokeratitis progressed to endophthalmitis. Two therapeutic penetrating keratoplasties (PKs) with iridectomy and intraocular amphotericin b were necessary to eradicate the fungal infection. RESULTS: visual acuity was restored to 20/25-3 with correction 9 months after initial presentation. There was no recurrence of fungal infection after the second therapeutic PK. CONCLUSION: The possible reasons for recurrence of fungal infection are discussed. The role of timely and aggressive medical and surgical intervention for fungal sclerokeratitis and endophthalmitis in restoring excellent vision is emphasized.- - - - - - - - - - ranking = 0.1keywords = body (Clic here for more details about this article) |
