1/19. 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) |
2/19. Tarantula keratouveitis.PURPOSE: To report a case of chronic bilateral keratouveitis, which was initiated after contact with a pet tarantula. methods: A 16-year-old male presented with a photophobia and redness of his eyes two days after handling a tarantula. He was found to have a number of linear corneal foreign bodies with subepithelial infiltrates. The infiltrates were found at varying levels of the corneal stroma with deposits on the endothelium. The anterior chamber had a mild cellular reaction. RESULTS: He was treated with topical steroid drops, which made him asymptomatic. However, he continued to have a mild persistent keratitis and iritis four months after the onset. CONCLUSION: Tarantula hairs may be associated with a chronic keratouveitis, which is usually self-limiting and responds well to treatment with topical steroids. Tarantula pet owners should be forewarned of the ocular dangers associated with handling these spiders.- - - - - - - - - - ranking = 1keywords = near (Clic here for more details about this article) |
3/19. Two remarkable events in the field of intraocular foreign body: (1) The reversal of siderosis bulbi. (2) The spontaneous extrusion of an intraocular copper foreign body.Two unusual events concerning intraocular foreign bodies are presented. The first patient had an occult or unsuspected intraocular foreign body. He showed iridoplegia with mydriasis, siderosis iridis, and an intraocular piece of iron lying posteriorly near the retina. The foreign body was removed and the patient regained normal iris color and pupillary activity. His vision remains 20/15 six years postoperatively dispite ensuing retinal detachment one year after removal of the foreign body. The second patient was a young boy injured by a blasting cap explosion. He lost one eye from the injury and had a piece of intraocular brass in his left eye. In spite of the development of chalcosis and a mature cataract the lens gradually shrank in the pupillary space permitting a clear aphakic area and 20/25 vision. The brass fragment migrated forward and inferiorly and was finally extruded under the conjunctiva five years later, where it was removed and chemically analyzed by x-ray diffraction.- - - - - - - - - - ranking = 1keywords = near (Clic here for more details about this article) |
4/19. Red coral keratitis.PURPOSE: We describe a 39-year-old woman who was seen for pain and blurred vision in the right eye that presented immediately after scuba diving several inches from a red coral reef. methods: The patient was found to have multiple superficial corneal foreign bodies with adjacent infiltrates on slit-lamp examination. She was treated with long-term topical corticosteroids. RESULTS: The infiltrates and symptoms gradually resolved after nearly 3 months of treatment. CONCLUSION: This case represents a form of keratitis caused by exposure to red coral. Possible mechanisms for the keratitis include type I and 4 hypersensitivities, resulting from the release of vasoactive substances. This is triggered by the red coral's nematocysts, or toxin-releasing organelles. Long-term corticosteroid treatment was effective in resolving the lesions.- - - - - - - - - - ranking = 1keywords = near (Clic here for more details about this article) |
5/19. An eyelid mass caused by a migrated hard contact lens.PURPOSE: To describe a mass caused by a hard contact lens in the upper eyelid. methods: We present a case of a 77-year-old man who complained of a mass in his right upper eyelid. He had previously undergone cataract surgery in the right eye at age 60 and then became a hard contact lens wearer. He underwent horizontal wedge-shaped excision of the tarsus at age 73. RESULTS: The mass in the right upper eyelid was excised. During the surgery, a hard contact lens was found embedded in the mass near the excision site of the tarsus. CONCLUSIONS: Hard contact lens migration through the wedge-shaped excision site of the tarsus into the upper eyelid, as seen in our patient, may be rare.- - - - - - - - - - ranking = 1keywords = near (Clic here for more details about this article) |
6/19. Retained anterior chamber cilium causing endophthalmitis after phacoemulsification.An 81-year-old white man had uneventful cataract surgery by an experienced surgeon. Three days postoperatively, he presented with endophthalmitis and was treated in accordance with the standard departmental protocol. During the recovery, a curvilinear foreign body was identified and subsequently removed from the interior anterior chamber. Histological examination confirmed the foreign body as an eyelash. The patient improved to a final corrected visual acuity of 6/9. The relevant literature is reviewed, and ways to prevent this potentially blinding but avoidable complication of intraocular surgery are presented.- - - - - - - - - - ranking = 1keywords = near (Clic here for more details about this article) |
7/19. 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) |
8/19. 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) |
9/19. 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 = near (Clic here for more details about this article) |
10/19. Subretinal neovascularization following metallic intraocular foreign-body trauma.Two patients developed subretinal neovascularization after chorioretinal injury from a metallic intraocular foreign body. In the first patient, a metallic foreign body struck the retina temporal to the macula and settled inferiorly. Eight months later, subretinal neovascularization developed at the initial impact site. In the second patient, a piece of silver wire became embedded in the retina and choroid near the macula, and subretinal neovascularization occurred six months later at the nasal end of the wire. In both patients, the subretinal neovascularization was confirmed with fluorescein angiography and successfully obliterated with argon laser photocoagulation.- - - - - - - - - - ranking = 1keywords = near (Clic here for more details about this article) |
