Orbital and Ocular Myiasis

Abstract

Abstract: Myiasis is the body’s infestation with maggots or eggs/larvae of certain flies. The infection is ether specific or non-specific. Although human Myiasis is rare, members of cyclorhabid, specifically the genus of Sarcophaga and Oestridae (Diptera), mainly produce myiasis [1]. Ocular and periocular myiasis are very rare and only few case reports have been published so far. Ophthalmomyiasis generally occurs in humans’ eyes, residing or working in close contact of livestock [2]. Older people, children, immunodeficient (people with orbital carcinomas, those with diabetes mellitus and with immunosuppressive drugs treatments) are affected usually [3]. However, there are few reports in which the infestation occurs in immuno-competent hosts. Compromised environmental sanitation and poor personal hygiene are often held as responsible factors. Infestation happens after fingers’ contamination after dealing with the infested livestock or by the fly itself. Under the skin, the larvae start the tissue penetrating and later they transform into large maggots. In the recent past ivermectin has largely been used with great success as non-invasive method of treating orbital myiasis [4]. The objective is to present a very rare case of ocular myiasis in a patient with infradiagnosed and careless squamous cell carcinoma of the upper eyelid.
