1/182. 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 = ocular (Clic here for more details about this article) |
2/182. 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 = 3keywords = ocular (Clic here for more details about this article) |
3/182. A case of bacterial endophthalmitis following perforating injury caused by a cat claw.A case of bacterial endophthalmitis following a perforating ocular injury caused by a cat claw is reported. The scleral wound was sutured immediately following the injury and systemic antibiotics were administered. Despite this treatment, endophthalmitis occurred 3 days after the injury. The endophthalmitis was resolved by pars plana vitrectomy, however preretinal reproliferation and retinal detachment subsequently occurred. After reoperation the retina was reattached and the corrected visual acuity improved from 10 cm/HM to 20/200. pseudomonas aeruginosa was detected in cultured vitreous humor that was collected during surgery. This case illustrates the possibility of endophthalmitis being caused by gram negative bacillus in cases of perforating injuries caused by animal claws. Perforating ocular injuries caused by animal claws are relatively rare. Here we report a case of endophthalmitis due to pseudomonas aeruginosa that occurred after a perforating injury caused by a cat claw. The eye was treated by pars plana vitrectomy.- - - - - - - - - - ranking = 1keywords = ocular (Clic here for more details about this article) |
4/182. 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.- - - - - - - - - - ranking = 2keywords = ocular (Clic here for more details about this article) |
5/182. Ocular injury caused by an air bag for a driver wearing eyeglasses.BACKGROUND: Although air bags have been shown to reduce the number of fatalities and serious injuries caused by motor vehicle accidents, there have been many reports of air bag-related ocular injuries. We recently treated air bag-related corneal laceration in a patient wearing eyeglasses at the time of a motor accident. CASE: A 38-year-old Japanese man was driving a car at approximately 40 km per hour when he struck a stopped 2-ton truck. He was wearing a three-point lap-shoulder seat belt. At impact, the driver's-side air bag deployed and struck the man on the left side of his face. He was wearing eyeglasses with glass lenses, and the air bag broke the left lens of his eyeglasses, and glass fragments lacerated his cornea. OBSERVATIONS: External examination showed multiple superficial abrasions of the skin and ecchymosis of the left side of his face. Slit-lamp examination of his left eye showed corneal laceration and hyphema. The lens had opacities and was covered with fibrin membrane. Repair of the corneal laceration and phacoemulsification of the lens were performed. Six months later, his best corrected visual acuity was 20/20 in the left eye. CONCLUSIONS: As cars are increasingly equipped with air bags, reports of air bag-related eye injuries have increased. To our knowledge, this is the first reported case of corneal laceration caused by a shattered lens in an air bag-related injury. Ophthalmologists should caution patients about the danger of eye injuries in air bag-equipped cars, and thought should be given to improving the materials for eyeglasses.- - - - - - - - - - ranking = 0.5keywords = ocular (Clic here for more details about this article) |
6/182. clostridium beijerinckii endophthalmitis secondary to penetrating ocular injury.endophthalmitis occurs in five to 10% of injuries involving intraocular foreign bodies. A 52 year old abattoir worker sustained such penetrating ocular trauma and developed fulminant endophthalmitis. clostridium beijerinckii was isolated from the vitreous humor. Intravitreal vancomycin and amikacin and intravenous penicillin and clindamycin were given. Despite therapeutic vancomycin and amikacin levels in the vitreous, vision was lost and enucleation was ultimately required.- - - - - - - - - - ranking = 3keywords = ocular (Clic here for more details about this article) |
7/182. Lamellar corneal autograft for corneal perforation.BACKGROUND: corneal perforation secondary to exteriorization of the haptic foot of the anterior chamber intraocular lens (IOL) is a rare complication in IOL surgery. CASE REPORT: A superior penetrating corneal defect developed in the right eye of a 74-year-old woman associated with exteriorization of the superior haptic of an anterior chamber IOL. methods: We describe the technique of repositioning and successful patching of the defect using a lamellar cornea-sclera rotational autograft. CONCLUSIONS: This technique is useful for small perforations when cornea donor tissue is not available.- - - - - - - - - - ranking = 0.5keywords = ocular (Clic here for more details about this article) |
8/182. 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 = 1.5keywords = ocular (Clic here for more details about this article) |
9/182. 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 = 6.5keywords = ocular (Clic here for more details about this article) |
10/182. eye injuries in a terrorist bombing: Dhahran, saudi arabia, June 25, 1996.OBJECTIVE: We report the experience of our institution in the evaluation and care of multiple simultaneous ocular trauma patients after a terrorist bomb attack on a united states military base in saudi arabia. DESIGN: Retrospective, noncomparative small case series. PARTICIPANTS: Three patients who received severe ocular injuries after a terrorist bombing. INTERVENTION: All patients underwent surgical repair of the injuries that were inflicted as a result of the terrorist bombing. MAIN OUTCOME MEASURES: Baseline ocular characteristics, intraoperative findings, surgical procedures, and final (3 years after injury) anatomic and visual outcomes were noted. RESULTS: Glass fragments caused by the blast were the mechanism of all the ocular injuries in these patients. All patients had primary repair of the injuries done in saudi arabia and were sent to our institution for tertiary care. Three of the four eyes injured had stable or improved visual acuity and one eye was enucleated. Two patients had no serious injury other than the globe trauma. One patient had extensive eyelid trauma and required serial procedures to allow fitting of a prosthesis. CONCLUSIONS: Blast-injury patients are at risk for open globe injury as a result of glass fragments. The types of injury that can occur from terrorist blasts can be extensive and involve all the tissues of the eye, the ocular adnexa, and the orbit.- - - - - - - - - - ranking = 2.5keywords = ocular (Clic here for more details about this article) |
