1/20. Ophthalmomyiasis in oman: a case report and comments.A case of external ophthalmomyiasis caused by the first instar larvae of the sheep nasal botfly (Oestrus ovis) has been reported for the first time from the Sultanate of oman, Southern arabia. Sixty larvae were removed from the left eye of a 21-year-old male student, who acquired the infection during a field trip. The manual removal of larvae using a swab stick was the only effective treatment. The larval characteristics are described with illustrations, and the status of O ovis ophthalmomyiasis in the middle east is discussed. The folk treatment administered for fly-mediated ophthalmomyiasis in oman is also reported. Ophthalmomyiasis may not be a serious public health problem in oman, but a nationwide survey of all myiases may be worthwhile.- - - - - - - - - - ranking = 1keywords = sheep (Clic here for more details about this article) |
2/20. Case report: ophthalmomyiasis externa in Dallas County, texas.Ophthalmomyiasis externa is an uncommon condition in north america. If not recognized and managed accordingly, it can be complicated by the potentially fatal condition ophthalmomyiasis interna. Ophthalmomyiasis externa is mainly caused by the sheep bot fly Oestrus ovis; thus, it is more common in farming communities. We report a case of ophthalmomyiasis externa in a young woman from Dallas County, texas, who had no known history of contact with farm animals.- - - - - - - - - - ranking = 1keywords = sheep (Clic here for more details about this article) |
3/20. 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 = sheep (Clic here for more details about this article) |
4/20. 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 = 6keywords = sheep (Clic here for more details about this article) |
5/20. Human external ophthalmomyiasis occurring in barbados.Human infection with the sheep nasal botfly Oestrus ovis occurs sporadically. In most cases, there is a history of a strike in the eye by the adult fly. Human O. ovis has been reported rarely from the americas. We report the first case of O. ovis infection in the caribbean region, which occurred in an urban area of barbados. The patient responded to removal of the larvae from the conjunctiva and symptomatic treatment.- - - - - - - - - - ranking = 1keywords = sheep (Clic here for more details about this article) |
6/20. 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 = 5keywords = sheep (Clic here for more details about this article) |
7/20. Conjunctival ophthalmomyiasis caused by the sheep nasal botfly (Oestrus ovis)Three patients had conjunctival ophthalmomyiasis caused by the ovine nasal botfly. All patients had a sudden onset of redness, tearing, and foreign-body sensation of the affected eye. One to nine Oestrus ovis first-instar larvae were removed from the bulbar or palpebral conjunctiva of each patient. Symptoms and clinical signs resolved after mechanical removal of the larvae. Specific taxonomic diagnosis of O. ovis larvae was determined on the basis of characteristic conformation of the terminal end of the larval caudal segment as seen by use of light microscopy.- - - - - - - - - - ranking = 4keywords = sheep (Clic here for more details about this article) |
8/20. Ophthalmooestriasis conjunctivae.A case of ophthalmooestriasis externa in a young woman is presented. The natural hosts of Oestrus ovis are sheep and goat. Occasionally man serves as intermediate host but then the larvae cannot mature. These larvae can give rise to a varying degree of inflammatory reactions of the conjunctiva. As the O. ovis larvae have no burrowing habits, infestation is limited to the outer membranes of the eye.- - - - - - - - - - ranking = 1keywords = sheep (Clic here for more details about this article) |
9/20. External ophthalmomyiasis caused by estrus ovis.External ophthalmomyiasis occurred in a 16-year-old white girl who was infected on Catalina Island, an endemic area for the sheep bot fly. With the patient under topical anesthesia, we isolated the larva, estrus ovis, removed it with jewelers' forceps, and examined it with light and scanning electron microscopy. The patient responded well to a treatment regimen of corticosteroids and antibiotics.- - - - - - - - - - ranking = 1keywords = sheep (Clic here for more details about this article) |
10/20. A case of ophthalmomyiasis in man by Oestrus ovis Linneaeus in Tehran (Insecta: diptera, Oestridae).Five first-stage-larvae were removed by soft and pointed blotting-paper from the left eye of a woman and they were identified as oestrus ovis. She was infected in Tehran and this is the first true case of ophthalmomyiasis due to sheep nasal bot fly in iran. Reports indicate that case of ophthalmomyiasis are more frequent in Iranian villages with different degree of severity. methods for prevention and treatments are also discussed.- - - - - - - - - - ranking = 1keywords = sheep (Clic here for more details about this article) |
