1/5. Subepithelial corneal amyloid deposits in a case of congenital glaucoma: a case report.PURPOSE: To report a rare association of subepithelial amyloid deposits in a long-standing case of congenital glaucoma. methods: A 5-year-old girl was brought to the emergency service with complaints of bleeding from the left eye after injury to the eye with the door handle. parents gave history of enlarged black portion of the eye since birth with increasing white opacity from the age of 6 months. On examination under general anesthesia, the left eye showed a limbal tear extending from 7 to 3.30 o'clock position and uveal prolapse. The right eye showed corneal edema, megalocornea, central white raised plaque, and high intraocular pressure. A diagnosis of bilateral congenital glaucoma with open globe injury, left eye, corneal scarring with degeneration, right eye was made and was advised enucleation. The enucleated eye was submitted for routine histologic examination. At a 3-year follow-up, there was an increase in the corneal scarring, with no significant improvement in vision. The child refused keratoplasty and was referred to low vision centre for visual rehabilitation. RESULTS: The enucleated eye was distorted and filled with blood. The cornea showed confluent pink homogenous wavy deposits in the subepithelial region. These deposits appeared brick red with congo red stain and showed apple green birefringence when viewed under polarized filters, confirming the amyloid nature of the deposits. There was loss of ganglion cell layer in the detached retina. CONCLUSION: The subepithelial amyloid deposits, presumably bilateral, in advanced case of congenital glaucoma were possibly secondary to the long-standing edema, scarring and vascularization. These secondary changes should be kept in mind as they could contribute to further deterioration in vision in advanced cases.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
2/5. Case of penetrating orbitocranial injury caused by wood.A case of retained intraorbital and intracerebral wooden foreign body following an orbitocranial penetrating injury through the lower lid of an adult is described. Initial failure to recognise the true nature of the injury led to intracerebral abscess formation and monocular blindness. diagnosis and management of such cases are discussed.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
3/5. Projectile metallic foreign bodies in the orbit: a retrospective study of epidemiologic factors, management, and outcomes.PURPOSE: Intraorbital projectile metallic foreign bodies are associated with significant ocular and orbital injuries. The authors sought to evaluate epidemiologic factors, the incidence of associated ocular and orbital injury, and the nature and necessity of surgical intervention in these cases. methods: charts of all patients with projectile intraorbital metallic foreign bodies seen at our institution (27) over the preceding 7 years were evaluated with respect to age, sex, type of injury, associated ocular and orbital injuries, location of the projectile (anterior, epibulbar, or posterior), postinjury visual acuity, and surgical intervention. RESULTS: The majority of patients were male, between the ages of 11 and 30, and had BB pellet injuries. Thirteen projectiles were lodged anteriorly, 4 were in an epibulbar position, and the remaining 10 were posterior to the equator. Twelve of 13 anterior, and 4 of 4 epibulbar foreign bodies were removed surgically, whereas only 2 of 10 posterior foreign bodies required surgery. No case of surgical intervention resulted in a decrease of visual acuity. Associated ocular injuries were both more common and severe in patients with posteriorly located foreign bodies. Final visual acuity was better at presentation and at discharge in patients with anteriorly located foreign bodies. CONCLUSION: Intraorbital projectile metallic foreign bodies can be a source of significant ocular morbidity. Management of these cases is dependent on the location of the projectile. Ancillary radiographic studies can be helpful. Surgery to remove the projectile should be considered in each case, but foreign bodies that are not readily accessible often may be left safely in place. Closer regulation of the pellet gun industry, with an emphasis on education and protective eyewear use, would be helpful in reducing these injuries.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
4/5. Air bag-related ocular injuries.This study reviewed the nature and severity of ocular and orbital air bag-related injuries at a large tertiary care referral center. The records of all patients treated by the ophthalmology trauma service for air bag-related ocular injuries between 1993 and 1995 were reviewed. Five patients were identified who had air bag-related ocular trauma. All of the patients who were referred to the ophthalmology trauma service for air bag-related ocular injuries had significant ocular or orbital injury. The extent and severity of the injuries were variable, ranging from orbital contusion to ruptured globe and retinal detachment. Although air bags substantially reduce the overall rates of mortality and morbidity associated with motor vehicle accidents, they also cause a variety of ocular injuries.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
5/5. Transorbital penetrating brain injury caused by a toy arrow: a case report.A case of a 9-year-old boy with a transorbital toy-arrow injury to the brain is presented. At admission he was in coma (glasgow coma scale of 6) with right hemiparesis and had a completely prolapsed left eye. Computerized tomography revealed intracranial haemorrhage and fracture of the orbital wall, which were treated conservatively. His left eye was enucleated due to massive injury. At the 6-month check-up the boy still show neurological signs of latent right hemiparesis. Disturbances, mostly cognitive, were noted on his psychological tests. A survey of the literature reveals no report of this nature in the paediatric age group. The necessity of continuous monitoring of new environmental risks as they occur, and the requirement for the prevention of recreational brain injuries in children, is stressed.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
