  1. The term ophthalmomyiasis refers to the infestation of the eye by the larval forms of flies (maggots) of the order Diptera

Ophthalmomyiasis is the deposition of larvae of flies in the human eyes Internal ophthalmomyiasis refers to invasion of the globe. The vector in acquiring external ophthalmomyiasis can be a finger after contact with an infested definitive host. A shepherd or rancher can transmit eggs and larvae to the eyelid of Oestris ovis, a fly whose definitive host is sheep or goat Most common symptoms of ophthalmomyiasis are irritation and redness, and in more than half of cases infestation is multiple. Ophthalmomyiasis interna is eye-compromising condition. Since there is reduced awareness among patients and medical professionals, the real number of ophthalmomyiasis cases is probably significantly higher than published External ophthalmomyiasis is a limited infestation of superficial periocular tissues, including conjunctival myiasis. Internal ophthalmomyiasis is characterized by the presence of the larva within the eye, which occurs when dipterous larvae penetrate the conjunctiva and sclera, and migrate into the subretinal space Ophthalmomyiasis is a relatively rare condition characterized by infestation of ocular and orbital tissues with fly larvae. It manifests as Ophthalmomyiasis externa and Ophthalmomyiasis interna. We describe a case of Ophthalmomyiasis externa in a 40 years old female who presented with ocular foreign body sensation, redness and lacrimation

Ophthalmomyiasis can occur in three forms: External, internal, and orbital.5 External ophthalmomyiasis is when the larvae deposit on the ocular surface. When the larvae penetrate it can be seen in the vitreous cavity or subretinal space it is known as internal ophthalomyiasis The organism was tentatively identified as the larval form (maggot) of a fly belonging to the species Cuterebra (C. Lamar Meek, PhD, oral communication, May 3, 2000). After several hours the larva had moved, seemingly by reversing its direction, inferior to the optic disc, where it was destroyed by laser photocoagulation ( Figure 4 ) Reference Gregory, Schatz and Laubach2Involvement of the eye and nose is termed ophthalmomyiasis and nasal myiasis, respectively. Ophthalmomyiasis is further subdivided into internal and external types, dependent on the presence of intra-ocular penetration.

ABSTRACT Ophthalmomyiasis, fly larvae infestation of the eye, is a rare condition that can have variable presentation depending on the type of fly, the ocular structures involved, and the level of penetration. A case of Ophthalmomyiasis extern Ophthalmomyiasis externa in humans is often caused by the larvae of the sheep nasal botfly, Oestrus ovis, and the Russian botfly, Rhinoestrus purpureus, which are found in sheep farming communities. Often the victims have the sensation of being struck by a foreign body or insect. Soon thereafter a painful inflammation develops, causing an acute. Ophthalmomyiasis is an ocular myasis du to man's parasitism by fly larvae, most frequently by Oestrus ovis which generally parasitizes sheep and goats nasal cavities. The infestation usually occurs by direct contact The ocular involvement occurs in less than 5% of all human myasis cases [2]. Ophthalmomyiasis is classified as externa Myiasis is an infection of the tissue spread by bot flies carrying Hypoderma tarandi, a parasite that lays eggs on reindeer and caribou and which sometimes infects humans. Myiasis is one of the oldest recorded diseases affecting man — as early as 520 B.C., Herodotus described a case of facultative myiasis in a woman.. Larvae that penetrate the eye cause a condition called ophthalmomyiasis Internal ophthalmomyiasis involves the burrowing of larvae into inner structures of the eyeball, while external ophthalmomyiasis refers to larvae on the conjunctiva, the mucous membrane covering the outer surface of the eye (Sucilathangam et al. 2013). In these cases, larvae do not pass to the L2 stage (Capelle 1966)

Six cases of external ophthalmomyiasis (i.e. myiasis of the coverings and adjuncts of the eyeball), have been observed by the author in ten years; in all, the patient's account was that something had struck the eye and caused pain, the result generally was conjunctivitis and swelling of the eyelids, and the diagnosis was made by observation of the living maggots Ophthalmomyiasis externa refers to the superficial infestation of ocular tissue. Conjunctival myiasis is the most common form of ophthalmomyiasis, and it is a relatively mild, self-limited, and benign disease. Patients commonly complain of acute foreign-body sensation with lacrimation, characteristically with an abrupt onset 38). Upon.

Ophthalmomyiasis refers to infestations of the eye and/or ocular annexa by larvae of the order Diptera and represents less than 5% of the cases of human myiasis Infestation of humans or other vertebrates by dipterous fly larvae is called myiasis. Larvae can infest several parts of the body, most commonly cutaneous tissue. Occasionally, infestation of ocular tissue could occur resulting in internal ocular or external (conjunctival or eyelid) ophthalmomyiasis.1-5 The most common species causing external ophthalmomyiasis in the US is the sheep botfly.

Deformutilation: Myiasis

Ophthalmomyiasis externa. Ophthalmomyiasis externa, caused by Oestrus ovis, is characterized by conjunctivitis, lid edema, and superficial punctate keratopathy in response to movement of larvae across the external surface of the globe. Larvae may appear within the cornea, lens, anterior chamber, or vitreous body but rarely undergo development. Ophthalmomyiasis is an uncommon condition but becomes significant in debilitated and compromised patients. Measures such as general cleanliness of surroundings, maintaining good personal hygiene, provision of basic sanitation, and health education have to be stressed, for preventing myiasis Ophthalmomyiasis is usually diagnosed by clinical examination. In ophthalmomyiasis externa larvae are found in the conjunctival sac, or rarely, in a warble on the eyelid.

Myiasis is defined as the infestation of live vertebrates (humans and/or animals) with dipterous larvae. In mammals (including humans), dipterous larvae can feed on the host's living or dead tissue, liquid body substance, or ingested food and cause a broad range of infestations depending on the body location and the relationship of the larvae with the host Ophthalmomyiasis involves the eye, orbit, and periorbital tissues . Human ophthalmomyiasis was first reported by Keyt in 1900 and later on by Elliot from India in 1910 .

We present here a case of ophthalmomyiasis caused by Phormia sp. fly larva in an enucleated eye of a patient. In June 2010, a 50-year-old man was admitted to Dankook University Hospital for surgical excision of a malignant melanoma. There was a mildly elevated but inactive chorioretinal scar superior to macula. The left eye was normal. We concluded that these findings were most likely the result of ophthalmomyiasis—an infection of the eye with fly larvae—in the distant past. No treatment is warranted, given the absence of inflammation or visual complaints External ophthalmomyiasis is caused by the infestation of ocular tissues by larvae belonging to the family of oestrids. 1 Although known in all regions, its frequency is higher in the Mediterranean basin.2 In our work, we report a case of external ophthalmomyiasis admitted to Guelmim Military Hospital (southern Morocco).
