1/20. Extraocular muscle cysticercosis presenting as Brown syndrome.PURPOSE: Report of a case of acquired Brown syndrome caused by infestation of the superior oblique muscle by cysticercus cellulosae. METHOD: Case seen in a referral practice. A 20-year-old man presented with recurrent attacks of conjunctivitis and diplopia in upgaze. Clinical examination of ocular motility established a diagnosis of acquired Brown syndrome of the right eye. Computed tomography of the right orbit unequivocally established the diagnosis of superior oblique muscle cysticercosis. The patient was started on systemic steroids and albendazole in the prescribed doses for a month. RESULT: Serial computed tomography scans of the orbit revealed resolution of the cystic lesion after a month. Clinically, although there was restoration of ocular motility in upgaze, mild restriction of movement of the right eye in levoelevation persisted. However, the patient was symptomatically better with amelioration of the recurrent conjunctivitis and diplopia in primary gaze. CONCLUSION: Extraocular muscle cysticercosis should be considered in the differential diagnosis of acquired motility disorder. The presentation of extraocular muscle cysticercosis as an acquired Brown syndrome is unusual. Response to medical therapy was satisfactory.- - - - - - - - - - ranking = 1keywords = infestation (Clic here for more details about this article) |
2/20. Subretinal cysticercosis.BACKGROUND: [corrected] cysticercosis is a parasitic infestation of different body organs by cysticercosis cellulosae, a larval form of the helminth, taenia solium, known commonly as pork tapeworm. Ocular involvement of cysticercosis is most common. Other sites of infestation include the central nervous system, subcutaneous tissue, skeletal muscles, and heart muscle. patients with ocular cysticercosis may be asymptomatic or suffer mild to severe vision loss. CASE REPORT: A patient presented with painless vision loss secondary to a parasitic infection by presumed subretinal cysticercosis. The clinical appearance, differential diagnosis, and management of subretinal cysticercosis are discussed. CONCLUSION: Prompt diagnosis and referral to a retinal surgeon are essential for the successful treatment of this condition.- - - - - - - - - - ranking = 2keywords = infestation (Clic here for more details about this article) |
3/20. CT in the diagnosis of isolated cysticercal infestation of extraocular muscle.AIM: To evaluate the use of computed tomography (CT) and ultrasound (US) to diagnose orbital cysticercosis, and present the diagnostic features. METHOD: US and CT were used to evaluate patients with proptosis. Four patients were diagnosed as having orbital myocysticercosis and treated with oral albendazole and corticosteroid. Follow-up was undertaken with US and CT. RESULT: US features were confirmatory of myocysticercosis in two eyes where as CT was effective in diagnosing the condition in all four eyes. In two patients the medial rectus was involved, in one the superior rectus and, in the other, the inferior rectus muscles. Serial US and CT revealed complete resolution of the lesions in 3 months. CONCLUSION: CT is useful method in diagnosing isolated orbital myocysticercosis. Our report demonstrated that ophthalmic signs and symptoms in the presence of proptosis, especially in an endemic region, should alert the clinician to the possibility of myocysticercosis. Though CT is superior, US can be used as a economical follow-up investigation.- - - - - - - - - - ranking = 4keywords = infestation (Clic here for more details about this article) |
4/20. There's a worm in my eye.OBJECTIVE: To report a case of an unusual worm infestation of the eye. CLINICAL FEATURES: A 28-year-old veterinary surgeon complained of the intermittent appearance of a worm in her eyes. Her previous camping travels in west and central africa suggested the diagnosis of loa loa, which was confirmed on surgical removal of the worm from beneath the conjunctiva. Laboratory investigations showed peripheral blood eosinophilia, negative thick blood film examinations for microfilariae and positive results of filarial serology. INTERVENTION AND OUTCOME: The worm was removed intact after incision of the overlying conjunctiva. diethylcarbamazine was prescribed and the patient remained asymptomatic in the subsequent 12 months. CONCLUSIONS: The sighting of a worm in the eye is rare in australia and usually occurs in immigrants or returned travellers. loa loa is the most common offending species and is identifiable and treatable.- - - - - - - - - - ranking = 1keywords = infestation (Clic here for more details about this article) |
5/20. Internal ophthalmomyiasis presenting as endophthalmitis associated with an intraocular foreign body.Ophthalmomyiasis interna infestation by fly larva can present in various forms. A 3-year-old girl with a 15-day history of pain, redness, and tearing of the right eye was referred to our clinic with the diagnosis of endophthalmitis associated with an intraocular foreign body, based on clinical and ultrasonographic findings. The patient underwent pars plana vitrectomy, during which an 8-mm long larva was encountered within the vitreous cavity. It was removed and identified as a cattle botfly. The patient developed a retinal detachment 1 month postoperatively, but the family refused further treatment and the patient was lost to follow-up. Ophthalmomyiasis should be included in the differential diagnosis of endophthalmitis and intraocular foreign bodies in patients from rural areas.- - - - - - - - - - ranking = 1keywords = infestation (Clic here for more details about this article) |
6/20. Ophthalmomyiasis in hawaii.Ophthalmomyiasis is the infestation of the eye by fly larvae. Commonly caused by Oestrus ovis, a female sheep botfly will accidentally deposit her larvae into a human eye, resulting in disease. Prompt recognition and treatment of this condition will improve patient care and reduce potential complications. We report a case of ophthalmomyiasis in a young man from Molokai who was infested while unloading a Christmas tree.- - - - - - - - - - ranking = 1keywords = infestation (Clic here for more details about this article) |
7/20. Intravitreal live gnathostoma spinigerum.Intraocular infestation by live gnathostoma spinigerum is a rare occurrence in humans. Most of the published reports are from South-East asia. We report a case of intravitreal gnathostomiasis, where the worm was removed live and intact by pars plana vitrectomy.- - - - - - - - - - ranking = 1keywords = infestation (Clic here for more details about this article) |
8/20. Ophthalmomyiasis caused by the sheep bot fly Oestrus ovis in northern iraq.myiasis is the feeding of fly larvae on vertebrates. The sheep bot fly larva of Oestrus ovis is a mammalian parasite of the skin, nose, ears, and eyes. When the larvae infest and feed on the structures of the eye, the condition is termed ophthalmomyiasis. Most often this infestation is limited to the external structures of the eye and is referred to as ophthalmomyiasis externa. The features of this condition are severe local inflammation, positive foreign body sensation, erythema, and lacrimation. Vision may or may not be reduced, depending on involvement of the cornea. A 20-year-old white male soldier sought treatment for an inflamed eye and an irritated cornea OS. His eyelids were swollen with marked periorbital edema and conjunctival erythema OS. On slitlamp examination, small whitish organisms were viewed on the conjunctiva OS. The organisms were removed, preserved, and sent to Nova Southeastern University where they were identified as O. ovis first-stage larvae. The patient was treated with antibiotic ointment, and the inflammation resolved within 1 week. O. ovis has a worldwide distribution, and although sheep are the preferred host, humans may also serve as an intermediate host in the organism's life cycle. This case represents one of several reports of ophthalmomyiasis in the middle east caused by O. ovis. U.S. troops stationed in iraq and surrounding areas are vulnerable to eye infestation by fly larvae, and health care providers need to include this condition in their differential diagnosis of anterior segment inflammatory disorders.- - - - - - - - - - ranking = 2keywords = infestation (Clic here for more details about this article) |
9/20. Orbital myiasis in a patient with a chronically exposed hydroxyapatite implant.We describe the clinical presentation of the first case, to our knowledge, of myiasis in an orbit with an exposed hydroxyapatite implant. We examined a 10-year-old boy with an 8-year exposure of an orbital implant. He had an infestation with maggots. The implant and the worms were surgically removed, allowing the socket to heal by secondary intention. The patient was able to wear a prosthesis 2 weeks later. The parasites were identified as belonging to Cochliomyia hominivorax, a fly responsible for the majority of cases of myiasis in the Western hemisphere.- - - - - - - - - - ranking = 1keywords = infestation (Clic here for more details about this article) |
10/20. Three cases of ophthalmomyiasis externa by sheep botfly Oestrus ovis in italy.Human infection with the sheep nasal botfly Oestrus ovis is sporadic and is often the consequence of an accidental deposit of the larvae by an adult botfly in the eye. This infestation results in external ophthalmomyiasis that, although a very rare condition, is more common among people living close to farming communities. We report three cases of O. ovis infestation which occurred in italy in a limited area of La Spezia province (Le Cinque Terre), italy during summer 2004. None of the patients had contact with wild or farm animals.- - - - - - - - - - ranking = 2keywords = infestation (Clic here for more details about this article) |
