“…If active signs of inflammation are absent, no treatment is indicated; otherwise, systemic corticosteroids may be beneficial 3 . Surgical intervention for parasite extraction 23 or laser coagulation may be attempted. Use of organophosphate larvicidal therapy is controversial when the parasite is within the eye because of the potential for increased inflammatory response to the dead parasite 3…”

Symblepharon secondary to ophthalmomyiasis externa in a dog

A 4-month-old crossbred female dog presented with complaints of poor vision and odd appearance of the eyes. At the age of a month, the animal was found lying in a railway road in a very bad condition and was rescued from death. At that time, the patient was presented with severe bilateral ocular discharge, and from both eyes, dipterous fly larvae were extracted. The dog was given symptomatic treatment (deworming, topical and systemic antibiotics, nutritional support) but never regained a normal eye appearance. At the time of the initial presentation, it had severe vision impairment because of bilateral cicatricial symblepharon, total in the left eye and occupying 3/4 of the cornea in the right eye. Surgery was proposed to attempt a resolution. Superficial keratectomy was performed in both eyes. After a midline incision in the cornea, the conjunctiva was dissected away. The conjunctiva was apposed to and sutured to the limbus and secured in the upper and lower conjunctival fornix. Additionally, in the left eye, a lateral canthotomy and canthoplasty were performed to enlarge the size of the eyelid opening. The corneal epithelium healed without complications, the patient regained vision, and after 36 months of follow-up, no recurrences were observed. To the authors' knowledge, this is the first report of symblepharon secondary to ophthalmomyiasis externa in a dog.

“…Ophthalmomyiasis is a frequent phenomenon among animals including sheep, horse, cattle, cat and dogs. Various researchers have reported the prevalence of ophthalmomyiasis in dogs (Ollivier et al 2006;Crumley et al 2011;Delgado 2012;Edelmann et al 2014) and cats (Harris et al 2000;Stiles and Rankin 2006). Although rare, it does occur in humans also.…”

Incidence of myiasis among humans—a review

Myiasis, the infestation of tissues of live humans and other vertebrate animals with dipteran larvae (maggots), is a phenomenon of widespread occurrence throughout the tropical regions of the world. It is commonly seen in domestic and wild animals but occurs rarely in man also. The tissue invasion in man by maggots is generally a well-recognized complication of neglected wounds. The condition may be asymptomatic but occasionally results in more or less severe problems and even death when larvae invade body cavities or areas that forbid their direct visual examination. Many cases of myiasis, however, usually do not reach the attention of medical practitioners because of the tendency of the mature larvae to migrate out of the lesion for pupation. In the present study, the authors reviewed the past literature describing the cases of human myiasis, causative fly species and predisposing factors for the onset of the same. The aim of the present manuscript is to provide a database for the future reference of medical entomologists, medical practitioners and veterinarians. Review of literature revealed that 37 fly species belonging to ten families were responsible worldwide for the onset of human myiasis. The incidence of myiasis among humans can be correlated to increasing fly populations, poor hygienic conditions and presence of domestic animals in the close vicinity. Other factors responsible for myiasis include neglected open wounds and foul-smelling discharge from natural body openings. Moreover, ignorance plays a key role in its occurrence since people are generally unaware about the actual cause and often correlate the condition to their superstitious beliefs. It is emphasized that the patients should not neglect their wounds and should take proper medical care; otherwise, myiasis may supervene.

“…obs.). More serious manifestations, especially in cats, involve the eyes (ophthalmomyiasis; Johnson et al, 1988;Harris et al, 2000;Wyman et al, 2005;Stiles and Rankin, 2006), respiratory system (nasal/pharyngeal/tracheal myiasis; Thirloway, 1982;Fitzgerald et al, 1996;Dvorak et al, 2000), or central nervous system (cerebrospinal myiasis; Cook et al, 1985;Hendrix et al, 1989;Glass et al, 1998;King, 2000). In these cases, clinical signs and symptoms can include anorexia, lethargy, inflammation, retinal damage, impaired vision, dyspnea, seizures, paralysis, or a combination, and definitive diagnoses can be difficult (many of the above references; also see Greenberg et al, 2004).…”

Five free-ranging mink, Neovison vison mink, from in or near the Fakahatchee Strand Preserve State Park, Collier County, Florida (26 degrees 00'N, 81 degrees 25'W), were examined for parasitic helminths. Nine species of helminths were identified (2 trematodes, 5 nematodes, and 2 acanthocephalans). The most prevalent parasites were Molineus patens (4 of 5 mink), mean intensity 173 (range, 12-342); Strongyloides sp. (4 of 5), mean intensity 48 (range, 1-170); Macracanthorhynchus ingens (immature) (4 of 5), mean intensity 2.5 (range, 1-4); and Alaria mustelae (3 of 5), mean intensity 59.3 (range, 11-127). Polymorphus brevis and Dirofilaria lutrae are reported from the mink for the first time.
