“…Reports on use of ivermectin in the treatment of orbital myiasis caused by C. hominivorax had been reported (De et al 2004;Osorio et al 2006). A rare case of orbital myiasis due to invasion of larvae of W. magnifica in a child was reported from India by Maurya et al (2012). Severe cases of external ophthalmomyiasis due to larvae of Wohlfahrtia sp.…”

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.

“…The one retrospective review found 6.15% of external ophthalmomyiasis cases occurred in individuals younger than 5 years. 37 The clinical manifestations of external ophthalmomyiasis fell into 3 groups: lid myiasis (48.6%), 24,27,39,46,62,79,101,114,116,120,122,129,139,158 ocular surface myiasis (45.9%), 5,15,22,39,44,65,66,84,104,115,130,138,145,150,166 and orbital infestation (25.4%). 41,129 The mean age for the overall cohort was 9.1 years (range, 12 days to 17 years).…”

Animal-inflicted ocular and adnexal injuries in children: A systematic review

Eye injury remains the leading cause of monocular blindness in children despite 90% of injuries being potentially preventable. Children interact with animals in a variety of situations, and the associated dangers may be underestimated. Animals are capable of causing ocular and adnexal injuries that are cosmetically and visually devastating. We examine the current literature regarding the nature and severity of animal-inflicted ocular and adnexal injuries in children.

“…The eggs may also be transferred by the patient as a result of scratching. (Maurya et al, 2012) Though our patient did not have any predisposing debilitating systemic disease, he had a long standing tumour, the focal necrosis of which could have acted as an attractant for flies. The trauma he sustained could have been an additional insult leading to further tissue necrosis.…”

Background: Ocular myiasis though rare, is usually found in association with basal cell carcinoma. It is rarer still in tumors other than basal cell carcinoma. We report a case of ocular myiasis in a glioma which is hitherto unreported to the best of our knowledge. Case: A 50 year old male presented with bleeding and maggots emanating from a tumourous outgrowth which had replaced his right eye. He complained of swelling and pain in his right eye for the last 2 years. Manual removal of maggots was carried out following which he underwent total excision of the mass and local debridement. Biopsy of the mass was consistent with astrocytoma. Conclusion: Myiasis though rare should be suspected in long standing neglected lesions with suggestive history. Infection, ischemic necrosis and malignancy coupled with overcrowding, poor living conditions, presence of excessive arthropods in the locality and low levels of hygiene drastically increase the risk of myiasis.
