1/21. 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) |
2/21. Loss of iridolenticular contact in eyes with exfoliation syndrome may protect against glaucoma.PURPOSE: To provide evidence for the hypothesis that dynamic iridolenticular contact predisposes to the development of glaucoma in exfoliation syndrome (XFS). methods: We present four patients with bilateral XFS and unilateral exfoliation glaucoma (XFG) whose normotensive eyes had suffered traumatic loss of dynamic iridolenticular contact. RESULTS: All 4 patients had bilateral XFS and developed XFG only in the untraumatized eyes. One patient had loss of iridolenticular contact in the traumatized eye, two had a nonreactive pupil, and one had had intracapsular cataract extraction at age 28. CONCLUSIONS: Loss of dynamic iridolenticular contact may help to protect against development of glaucoma in eyes with XFS.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
3/21. Combined cataract extraction and submacular blood clot evacuation for globe perforation caused by retrobulbar injection.A 45-year-old woman, originally scheduled for cataract surgery in the left eye, was referred for management of a globe perforation noticed after the retrobulbar injection of an anesthetic solution. There was a moderate degree of vitreous hemorrhage, and initial visual acuity was hand movement. A submacular blood clot of about 4-disc diameter was detected when the vitreous hemorrhage gradually cleared. One week after the incident, combined phacoemulsification, intraocular lens implantation, pars plana vitrectomy, and submacular clot removal using tissue plasminogen activator (tPA) as an adjunct were performed. Recovery was uneventful. At the last follow-up 6 months after surgery, best corrected visual acuity was 20/30.- - - - - - - - - - ranking = 4keywords = extraction (Clic here for more details about this article) |
4/21. indocyanine green staining in traumatic cataract.We report the first case of indocyanine green (ICG) being used in an eye with an anterior capsule that was not completely intact. We found that ICG seems to have a selective affinity for the anterior capsule over cortical lens material. The patient had a corneal perforation with a wire and developed endophthalmitis requiring pars plana vitrectomy with intravitreal antibiotics. He subsequently developed a white traumatic cataract with an anterior capsule tear. Five months after the injury, he had cataract extraction. indocyanine green was used to better visualize the anterior capsule before capsulotomy. The anterior capsule stained green, but the cortical material exposed to ICG did not stain.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
5/21. 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) |
6/21. pseudallescheria boydii keratitis.We treated a case of post-traumatic keratitis caused by the soil saprophyte, pseudallescheria boydii. The injury was caused by a wood splinter which produced a perforating corneal laceration that was primarily repaired. Signs of corneal infection were not evident until the fourth postoperative week. The organism was eradicated by topical miconazole and natamycin. Subsequent penetrating keratoplasty combined with cataract extraction and intraocular lens implantation has achieved a good visual outcome.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
7/21. 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) |
8/21. 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) |
9/21. 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) |
10/21. 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) |
