Myiasis is infection of tissues or organs of animals or man by larvae of a fly. The common sites are skin wounds. Eyes, nose, nasal sinuses, throat, and urogenital tract are less common sites [1-3]. Ocular involvement occurs in about < 5% of all cases of human myiasis [4]. Ophthalmomyiasis is classified as ophthalmomyiasis externa if the larvae are present on the conjunctiva, and ophthalmomyiasis interna when there is intraocular penetration of larvae [5]. Cases of ophthalmomyiasis externa have been reported from various parts of the world [6-8]. However, this condition is rare in India and there are only a few reported cases [5,9-12]. To the best of our knowledge, no case of ophthalmomyiasis externa caused by Oestrus ovis(the sheep nasal botfly) has been reported from this part of India. The present case therefore highlights the awareness among the ophthalmologists regarding larval conjunctivitis in spring and summer season, with timely diagnosis and treatment of this rather rare infestation.
