1/31. 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 = 1keywords = extraction (Clic here for more details about this article) |
2/31. 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 = 2keywords = extraction (Clic here for more details about this article) |
3/31. Fluorescein angiographic findings in ocular siderosis.PURPOSE: To report a case of siderosis from a retained intraocular iron foreign body manifesting localized retinal capillary nonperfusion documented by fluorescein angiography. methods: Case Report. In a 35-year-old man with decreased vision in the left eye, studies included fundus photography, fluorescein angiography, visual field testing, and electrophysiology. Surgical foreign body extraction and histopathologic examination were performed. RESULTS: Preoperatively, in the left eye, humphrey visual fields and electrophysiology testing revealed marked depression. fluorescein angiography demonstrated nasal capillary nonperfusion with occlusion of the second- and third-order arterioles extending along a gradient from the foreign body. Microscopic examination of the lens capsule confirmed the diagnosis of siderosis secondary to a retained iron foreign body. CONCLUSION: Extensive capillary nonperfusion may be associated with a retained iron intraocular foreign body, as documented by fluorescein angiography.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
4/31. Pars plana vitrectomy foreign body extraction assisted with a 24-gauge needle tunnel.A 54-year-old man presented with corneal laceration, traumatized iris, small vitreous hemorrhage, lens opacity, and a 13-mm intraocular foreign body embedded in the retina. Pars plana vitrectomy and argon laser photocoagulation were performed. Using intraocular forceps, the object was forced into a 24-gauge needle that was inserted through the sclerotomy. The foreign body and the needle were removed from the eye. phacoemulsification with foldable intraocular lens implantation in the ciliary sulcus was performed. Seven days after the surgery, the patient's visual acuity was 20/20 with spectacle correction of -3.5 diopters. The use of a needle tunnel during pars plana vitrectomy should be considered in similar cases of large, irregular intraocular foreign bodies to avoid severe and irreversible damage to the adjoining tissues.- - - - - - - - - - ranking = 4keywords = extraction (Clic here for more details about this article) |
5/31. Periocular migration of an intraocular lens.A woman presented with a painful eye 6 weeks after cataract extraction and intraocular lens implantation. In the past she had had a sector iridectomy for iris bombe caused by chronic anterior uveitis. On examination the three central corneal sutures were absent, whilst the medial and lateral sutures had broken and were protruding from the section. The eye was quiet and the section intact. Combined clinical and ultrasound examination failed to locate the intraocular lens. Four months postoperatively, while being fitted for contact lenses for the correction of aphakia, the intraocular lens appeared from the superior fornix.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
6/31. Novel approach in the treatment of intravitreal foreign body and traumatic cataract: three case reports.We present a novel surgical technique of simultaneous traumatic cataract extraction, internal magnet removal of the intraocular foreign body, and implantation of a posterior chamber intraocular lens in the eyes of three patients with traumatic cataract and ferrous intraocular foreign body retained in the anterior part of the vitreous body. Primary corneal wound repair, cataract extraction, anterior vitrectomy, removal of the intraocular foreign body through the corneoscleral limbal incision by using intraocular magnet, and intraocular lens implantation were performed. All intraocular foreign bodies and corneal entry sites were not larger than 3 mm. After a median follow-up of 13.6 months (range, 9-21 months), visual acuity ranged from 0.6 to 1.0. There were no early or late postoperative complications. According to our experience, an anterior approach in the surgical technique of simultaneous cataract extraction, intraocular foreign body extraction and implantation of a intraocular lens in the capsular bag is possible in selected patients with intraocular foreign bodies positioned in the anterior vitreous, behind the lens, with no associated retinal pathology.- - - - - - - - - - ranking = 4keywords = extraction (Clic here for more details about this article) |
7/31. Bilateral intraocular foreign bodies simulating crystalline lens.PURPOSE: To report a case of large bilateral intraocular foreign bodies mistaken for crystalline lens on computed tomography (CT). DESIGN: Case report. methods: A 24-year-old man was referred after bilateral open globe repair following a motor vehicle accident. Preoperatively, the CT scan had been read as "Right eye posteriorly dislocated lens. No evidence of foreign bodies." RESULTS: The patient underwent left eye cataract extraction with removal of a 7 x 5 x 5 mm piece of glass buried in the crystalline lens. The patient subsequently underwent right eye pars plana vitrectomy, removal of another piece of glass measuring 6 x 5 x 5 mm, retinal detachment surgery, and corneal grafting. CONCLUSIONS: Current safety standards require auto glass to fracture into pieces of a specific size to minimize laceration and missile injury. These pieces of glass may have a shape and size similar to the crystalline lens but have higher radiodensity on CT scan.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
8/31. Lenticular chalcosis--electron microscopic and microprobe analysis. A case report.A patient with a retained intra-ocular foreign body had a lens extraction for lenticular chalcosis. The lens capsule, examined under an electron microscope, showed copper particles deposited in the basement membrane. The lens capsule and foreign body were examined with an electron microprobe beam. This method proved to be an efficient method of qualitative and quantitative analysis of the contents of the foreign body.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
9/31. Persistence of intralenticular squamous epithelium after trauma.An intralenticular foreign body with associated squamous epithelium was found incidentally at cataract extraction in a 61-year-old man 23 years after a penetrating injury. The squamous epithelium produced no adverse effects. To our knowledge this is the first report of persistence of surface squamous epithelium within the lens.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
10/31. Spontaneous fracture of an implanted posterior chamber intraocular lens.PURPOSE: Spontaneous fracture of an intraocular lens (IOL) haptic is a rare complication of cataract surgery. The authors report a case of spontaneous fracture of an implanted posterior chamber IOL. CASE: Five years ago, a 12-year-old patient underwent linear lens extraction, posterior capsulotomy, and anterior vitrectomy due to traumatic cataract and received a polymethyl methacrylate (PMMA) biconvex posterior chamber IOL implanted in ciliary sulcus. Five years later, IOL optic was found in anterior chamber with its haptics broken from the optic-haptic junction. DISCUSSION: The broken haptic was examined with scanning electron microscopy. The fracture site of the haptic was on the optic-haptic junction. The fractured surface had a regular appearance. CONCLUSIONS: To our knowledge, this is the fourth report of spontaneous fracture of an implanted posterior chamber IOL.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
