External ophthalmomyiasis by Oestrus ovis larvae: A Rare Case Report

Abstract

Myiasis is defined as the infestation of live vertebrates (humans and animals) with dipterous larvae. The Prevalence of Myiasis of different organs has been reported from various regions in the world. Ophthalmomyiasis, or oculomyiasis, is the infestation of any anatomic structure of the eye by the larvae. In the Indian population, reporting of ocular myiasis cases has been very few, and in this part of the country, it is infrequent. Hereby we present a human case of External Ophthalmomyiasis caused by the larvae of a sheep bot fly, Oestrus ovis, for the first time from Sarojini Devi Eye Hospital, a tertiary eye care hospital in Hyderabad city in the Telangana State of India. J Microbiol Infect Dis 2021; 11(3):159-161.
