1/426. 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.

2/426. 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.

3/426. Post-traumatic endophthalmitis: causative organisms and visual outcome.

    PURPOSE: Post-traumatic endophthalmitis makes up a distinct subset of intraocular infections. The purpose of the present study was to identify the causative organisms and record the visual outcome after infectious endophthalmitis in eyes with penetrating trauma. methods: We reviewed 18 consecutive cases of culture-positive endophthalmitis that developed after penetrating ocular trauma. All cases were treated with pars plana vitrectomy and intravenous and intraocular antibiotics. RESULTS: The 15 males and 3 females ranged in age from 4 to 43 years (mean 25.1 /- 11 years). Nine (50%) had intraocular foreign bodies. A single species was isolated in 16 cases, and multiple organisms in two. staphylococcus epidermidis and gram-negative organisms were the most frequent and were cultured either alone or in association with other organisms in respectively five (27.7%) and four cases (22.2%). clostridium perfringens was isolated in three cases (16.6%). bacillus was not found as a cause of endophthalmitis. Final visual acuity was better than 20/400 in eight cases (44%). In five cases (27.7%), the eye was saved but visual acuity was counting fingers. Two eyes (11%) had no light perception. The remaining three eyes (16.6%) were enucleated or eviscerated. clostridium perfringens was isolated from two eyes and aspergillus niger from one. Postoperative retinal detachment developed in four eyes, which were successfully operated. CONCLUSIONS: Organisms isolated in this series were similar to those in previous reports of post-traumatic endophthalmitis from other parts of the world, except that the frequency of clostridium perfringens isolation was high and no bacillus species were cultured. In view of its devastating outcome, post-traumatic endophthalmitis must be treated promptly with vitrectomy and intravitreal antibiotics. ( info)

4/426. 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. ( info)

5/426. 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. ( info)

6/426. 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. ( info)

7/426. 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. ( info)

8/426. Caterpillar setae in the deep cornea and anterior chamber.

    PURPOSE:To report a case of caterpillar setae embedded in the deep cornea and anterior chamber. methods: A 26-year-old man was struck in his right eye by a caterpillar (Dendrolimus punctatus walker). Severe conjunctival injection, chemosis, and erosion of the cornea developed immediately. Numerous setae fragments were found to be embedded into the palpebral conjunctiva and deep cornea, extending into the anterior chamber near the anterior iris surface. RESULTS: After partial removal of the setae under a microscope, the inflammation subsided and visual acuity improved to RE: 20/20. CONCLUSION: Caterpillar setae are sharp enough to penetrate the cornea and extend into the anterior chamber. ( info)

9/426. "A little reminder does no harm": case report.

    A case of falsified non-accidental ocular injury of a 29 year old male is presented. The importance of an accurate history and appropriate investigations in the management of ocular injuries is highlighted to promote a high standard of health care delivery in zimbabwe. ( info)

10/426. 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. ( info)
