Ivermectin treatment for massive orbital myiasis in an empty socket with concomitant scalp pediculosis

Abstract

We report a rare case of massive orbital myiasis following recent lid injury, occurring in the empty socket of an elderly lady, who had concurrent scalp pediculosis. The orbital myiasis was effectively treated with the broad-spectrum antiparasitic agent, ivermectin, thus precluding the need for an exploratory surgery. Ivermectin was also effective in managing the concurrent scalp pediculosis.

Ocular myiasis in a glioma: a case report

“…(Puthran et al, 2012;Ziemianski et al, 1980) It is caused by flies which lay eggs in dead or decaying tissue and open wounds, most commonly in animals. Man is considered an accidental host.…”

“…Man is considered an accidental host. (Puthran et al, 2012) Diptera flies are considered responsible for ophthalmomyiasis. The species of the larva in this case was not established but a good majority of ophthalmomyiasis cases are caused by Oestrus ovis (sheep nose botfly), Dermatobia hominis (human botfly), Cochliomyia hominivorax (screw worm), Hypoderma bovis (ox warble fly) and Lucilia sericata (greenbottle fly).…”

“…Trauma, as in this case, is thought to be an important risk factor leading to maggot infestation. (Puthran et al, 2012) Flies are attracted to the wounds to the foul smell of the focal necrosis secondary to the ulcer, which then lay eggs directly at the affected site. The eggs may also be transferred by the patient as a result of scratching.…”

Ophthalmomyiasis and Basal Cell Carcinoma: a Case Report

“…Ophthalmomyiasis is usually caused by Oestrus ovis, and less commonly by Dermatobiahominis, and very rarely by L. sericata (9). Generally, these flies do not parasitize the hosts, they just lay their eggs in necrotic tissues, corpses and open wounds especially in animals, therefore, humans are the accidental hosts and trauma is known as an important risk factor (13). L. sericata is found in the tropical regions and it prefers humid and warm weather, therefore, it can be found around coastland dry regions (14).…”

Orbital myiasis caused by green bottle fly

“…Man is thus an accidental host, and trauma is an important risk factor. 4 Although maggot infestations are common in the tropics, only between 5 and 14 per cent of all cases involve the ocular tissues, and most ophthalmologists have little experience with this condition. 5 Our patient presented with a recent lid injury and poor hygiene.…”
