1/9. 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.- - - - - - - - - - ranking = 1keywords = near (Clic here for more details about this article) |
2/9. Surgical management of strabismus after rupture of the inferior rectus muscle.BACKGROUND: rupture of an inferior rectus muscle is an uncommon problem. The resulting absence of infraduction and large hypertropia that result when the muscle cannot be repaired are challenging to manage surgically. methods: We treated 2 patients who had traumatic rupture of the inferior rectus muscle. Both patients underwent an inferior transposition of the inferior halves of the medial and lateral rectus muscles without disinsertion (modified Jensen transposition procedure). RESULTS: Both patients had a persistent small overcorrection in the primary gaze position. One patient was treated with a second strabismus surgery consisting of a recession of the contralateral superior rectus muscle; the other was treated with prism glasses. Both achieved restoration of depression to approximately 40 degrees and single binocular vision in the primary position at distance, near, and in the reading position. CONCLUSION: This modified Jensen transposition procedure of the horizontal rectus muscles appears to be highly effective in the treatment of the hypertropia and infraduction deficit produced by rupture of the inferior rectus muscle. It also appears to be suitable for use in situations when other rectus muscles are absent or unavailable for surgical manipulation.- - - - - - - - - - ranking = 1keywords = near (Clic here for more details about this article) |
3/9. Favorable outcome using a black diaphragm intraocular lens for traumatic aniridia with total iridectomy.A 25-year-old man had a penetrating injury to the left eye. Ocular examination revealed a full-thickness corneal laceration, total aniridia, anterior capsule rupture, and microscopic hyphema. Ten days after the immediate primary-repair surgery, aspiration of the lens secondary to traumatic cataract was performed. Four months later, a black diaphragm intraocular lens was implanted. Postoperatively, the best corrected visual acuity was 20/20 in both eyes. Multifocal spectacles were prescribed to provide the near and far vision required for the patient's job. Normal intraocular pressure and acceptable photophobia were noted during the 18-month follow-up.- - - - - - - - - - ranking = 1keywords = near (Clic here for more details about this article) |
4/9. Orbitocranial wooden foreign body diagnosed by magnetic resonance imaging. Dry wood can be isodense with air and orbital fat by computed tomography.In computed tomographic (CT) scans, a wooden foreign body can appear as a lucency with nearly the same density as air or fat, and it can be indistinguishable from orbital adipose tissue. magnetic resonance imaging (MRI) can localize these wooden foreign bodies in the orbit. We studied a case in which a wooden golf tee lodged in the right optic canal of a nine-year-old boy. The head portion lodged in the orbital apex and the tip entered the interpeduncular fossa. Clinical examination revealed a right paranasal laceration; the right eye had no light perception and a peripapillary hemorrhage, but was otherwise normal. Surgical exploration and evaluation by CT failed to locate the foreign body. However, the golf tee was demonstrated by MRI as a low intensity image. Although it was removed by craniotomy with good neurological results, bacterial panophthalmitis led to enucleation of the eye. This case emphasizes the diagnostic value of MRI and the hazards of retained wooden foreign bodies.- - - - - - - - - - ranking = 1keywords = near (Clic here for more details about this article) |
5/9. suicide-related perforating injury of globe with nail gun.A case is reported of nail gun injury due to suicide attempt involving both orbits, frontal lobe and abdomen, which resulted in an unusual posterior perforation of the left globe. Injury was inflicted with a total of eight nails. Three nails entered the left orbit, one of which perforated the posterior aspect of the left globe. One nail entered the right orbit involving the optic nerve and crossed the midline to finish in the left sphenoid sinus. Three nails entered the frontal lobe near the midline and the final nail pierced the left lobe of the liver. The left eye underwent primary repair, lensectomy and vitrectomy with silicone oil and achieved a visual acuity of 6/60, 3 months post removal of oil with sutured posterior chamber intraocular lens. The right eye suffered traumatic optic neuropathy and currently has a visual acuity of 6/36 due to senile cataract formation. No other serious sequelae resulted from the other injuries and the patient has recovered from his episode of depression.- - - - - - - - - - ranking = 1keywords = near (Clic here for more details about this article) |
6/9. Penetrating craniofacial injuries in children with wooden and metal chopsticks.Penetrating craniofacial injuries with chopsticks in children are peculiar accidents in the Oriental culture. All 10 cases previously reported were caused by wooden chopsticks that required surgical operations. However, there are no reported injuries with metal chopsticks in the past literature which should have been as common as that of wooden chopstick injuries in asia. We evaluated the difference of injury patterns and clinical observations between wooden and metal chopstick injuries. We reviewed 6 treated children with penetrating craniofacial injuries from chopsticks: one wooden and five metal chopsticks. One child who had penetration through the nasal cavity presented with temporary rhinorrhea, another with mild hemiparesis, and one child with temporary upward gaze limitation of the left eye. Radiological examination revealed 1 patient with epidural hemorrhage, 1 patient with minimal subdural hemorrhage, and 4 with intracerebral hemorrhage that were fortunately too small to receive surgery. We performed surgical procedure only for a child who had a wooden chopstick that had impacted into the temporal cortex. We followed up all 6 children for more than 1 year, and found that all had fully recovered to near-normal neurological status. We observed that penetrating craniofacial injuries with metal chopsticks rarely require surgical intervention and usually results in good outcome because the resultant wound is usually small without broken fragments compared to injuries with wooden chopsticks.- - - - - - - - - - ranking = 1keywords = near (Clic here for more details about this article) |
7/9. Penetrating corneal fish-hook injury.A healthy 13-year-old female was struck in the left eye by a fish-hook while fishing. The fish-hook penetrated the cornea, passed the anterior chamber and exited from a second corneal site near the limbus. The fish-hook was removed by cutting its shank and pushing it out of the wounds. visual acuity was 20/20 OS after surgery. Mild corneal scarring was present at the penetration sites. We would like to report this case because there is a limited number of patients with penetrating corneal fish-hook injuries and this case presents the only female patient in the ophthalmological literature who suffered corneal fish-hook injury.- - - - - - - - - - ranking = 1keywords = near (Clic here for more details about this article) |
8/9. Removal of a corneal foreign body through a lamellar corneal pocket.A piece of glass was found in the posterior central cornea of a 43-year-old victim of a motor vehicle accident. The original entry of the foreign body had healed and epithelialized. This foreign body was removed through a peripheral corneal incision and corneal stromal pocket extended to the glass particle. This technique avoids creation of a corneal incision near the optical axis and prevents unwanted distortion of the corneal topography. The authors report this case to emphasize the importance of preserving corneal topography in corneal surgery.- - - - - - - - - - ranking = 1keywords = near (Clic here for more details about this article) |
9/9. Intracranial penetrating injuries via the optic canal.Two cases of intracranial penetration of a plastic or wooden chopstick via the optic canal are described. CT scans showed the chopsticks as linear hypodense structures in the suprasellar cistern contiguous with the optic canal. In one case, MR imaging was performed, which clearly depicted the foreign body and adjacent brain structures. Although they are extremely rare, transorbital intracranial penetrating injuries via the optic canal require physicians' awareness.- - - - - - - - - - ranking = 1keywords = near (Clic here for more details about this article) |
