1/9. Ocular filariasis: not strictly tropical.A 65-year-old man consulted for a discomfort in the right eye that had suddenly appeared the evening before. The examination revealed a white worm localized under the temporal bulbar conjunctiva. After extraction, the parasitological characteristics identified the worm as dirofilaria repens (Nochtiella subgenus). This is a parasite of canids and felids, usually nonpathogenic to humans, but which can be transmitted through mosquito bites, especially around the Mediterranean basin. The simple extraction of the worm, encysted under the skin or under the conjunctiva, cures the patient.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/9. Disseminated hydatid disease involving orbit, spleen, lung and liver.Orbital hydatid disease is rare, even in endemic areas. We present a case of disseminated hydatid disease involving the orbit, spleen, lung and liver in a lady aged 35 years. Based on a typical clinical presentation, presence of eosinophilia, a positive indirect haemagglutination test for hydatid disease and presence of similar disseminated, anechoic cystic masses in the liver, lung, spleen and orbit on imaging studies, the diagnosis of hydatid cyst was seriously considered before surgery. Aspiration of the cyst, followed by cryo-extraction of the cyst wall through transconjunctival route was safely performed. Histopathological examination confirmed the diagnosis. In conclusion, multisystemic involvement of liver, lung and spleen in a case of orbital hydatid cyst has never been reported before. The surgical technique adopted in this case is safe and effective.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
3/9. Case report: intraocular gnathostomiasis in vietnam.This is the report of the first case of intraocular gnathostomiasis diagnosed in vietnam. The disease progressed in two months in two distinct phases: in the first phase, the patient had swellings, which appeared at different times and in different locations, on his face--this phase lasted around one month; the second phase was the embedding of the parasite in the vitreous cavity of the right eye and uveitis. Surgical extraction of a living gnathostoma larva was carried out. Based on morphological, histological criteria, the larva may have been an atypical third-stage of gnathostoma spinigerum.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
4/9. Case report: intraocular cysticercosis.A case of intravitreal cysticercosis causing left uniocular cataract and eventual left visual loss in a healthy female Nigerian is presented. The diagnosis of cysticercus celulosae was not made until the patient had left cataract extraction done. The cysticercus larva found its way into the anterior chamber and this stimulated severe ocular inflammation. The use of antihelminthic and systemic steroid caused amelioration of the patient's ocular inflammation and symptoms. The review of literature on ocular involvement and the management of cysticercosis are discussed.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
5/9. External ophthalmomyiasis caused by Dermatobia hominis. A retrospective study of nine cases and a review of the literature.PURPOSE: To report nine cases of external ophthalmomyiasis caused by Dermatobia hominis. methods: Retrospective, non-comparative, interventional case series. Participants consisted of patients (n = 9) presenting at Cayenne Hospital between 1968 and 2003. The location and number of larvae, the larval stage, and the medical and surgical procedures applied were studied in each case. RESULTS: Seven patients had palpebral myiasis (including one with three larvae) and two had conjunctival myiasis. Every patient had palpebral oedema. The larval respiratory pore was located on the palpebral skin or free margin or on the conjunctiva. Movements were present within the lesion in at least three patients. petroleum ointment or ivermectine solution was used in at least four patients to smother or kill the larvae. Extraction under local anaesthesia was possible in six patients, while three required general anaesthesia. CONCLUSION: Several larvae may be present in a patient. Topical ivermectine may help to kill the larvae before extraction is attempted.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
6/9. Ocular angiostrongyliasis in a child--first case report from india.A rare case report of angiostrongylus cantonensis (rat lung worm) from the eye is presented here. This worm generally causes eosinophilic meningo-encephalitis and accidentally infects humans by ingestion of uncooked snails, slugs, frogs etc. The child was presented to us with diminished vision in left eye. Slit lamp examination showed an actively motile worm in the anterior chamber. Surgical extraction of the worm was performed and it was identified as A. cantonensis. This is the first case of ocular A. cantonensis infection from india with no signs or symptoms of meningitis. After surgery, the visual acuity of the patient returned to normal.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
7/9. Periorbital dirofilariasis.A differential diagnosis of inflammatory periocular soft tissue masses includes sarcoidosis, ruptured dermoid cyst, infectious abscess, metastatic neoplastic disease, and idiopathic pseudotumor. The authors present the case of a 42-year-old woman with a periocular inflammatory mass caused by dirofilaria of a nematode classification as Dirofilaria tenuis. The extraction of the worm was curative and the patient has been symptom-free for the ensuing 12 months. This zoonotic infection, spread by mosquito vectors from animal hosts to humans, is rarely encountered in the United States as a cause of periorbital inflammation. A history of migratory swelling and residence in, or travel to, endemic areas (the southeastern united states) should suggest the possibility of Dirofilaria infection.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
8/9. Pars plana vitrectomy for retinal detachment due to internal posterior ophthalmomyiasis after cataract extraction.BACKGROUND: The authors report a case of posterior internal ophthalmomyiasis causing vitreous haemorrhage and retinal detachment after uncomplicated cataract extraction. CASE REPORT: The patient suffered an abrupt vitreous haemorrhage 9 days after ECCE and posterior chamber IOL implantation. After 2 months the haemorrhage did not clear up and a retinal detachment arose. The patient underwent encircling scleral buckle, pars plana vitrectomy and fluid-gas exchange. In course of intervention the surgeon removed from the vitreous chamber a 14-mm-long round worm subsequently identified as a dipterous larva of the sarcophagidae family. DISCUSSION: The patient showed no sign of subretinal tracking or retinal breaks or holes. The sclerocorneal surgical wound seems the most likely site of entrance of the parasite, and this would then be the first reported case of myiasis with no RPE tracking.- - - - - - - - - - ranking = 2.5keywords = extraction (Clic here for more details about this article) |
9/9. Ocular leech infestation in a child.PURPOSE: To describe a patient with manifestations of ocular leech infestation. METHOD: Case report. RESULTS: The ocular foreign body was identified as a leech, Limnatis nilotica, by parasitologic examination. The leech was extracted, and the patient began using topical antibiotic and cycloplegic agents. By the third day after extraction, the patient had no obvious symptoms or signs, except for a limited subconjunctival hemorrhage, and no epithelial defect on the cornea was observed. CONCLUSIONS: Ocular leech infestation should be considered in patients with a history of swimming in streams and lakes. attention should also be given to ocular leech infestation in the differential diagnosis of ocular trauma with iris prolapse.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
