We describe a case of subconjunctival dirofilariasis from South India. The worm was identified by detailed morphologic study.
Subconjunctival dirofilariasisDirofilaria tenuis
A 75-year-old male presented with redness and irritation of the left eye. Ophthalmic examination revealed a thin white live worm wriggling around superior conjunctiva. The worm removal was done under local anesthesia and identified as an adult female Dirofilaria tenuis. D. tenuis rarely causes subconjunctival dirofilariasis in Asia. The parasite was identified by detailed morphologic study in wet preparation. Dirofilaria is identified by filariform; body cuticle is finely striated. Mouth without lips and encircled by six to ten papillae and head papillae are insignificant. Esophagus is relatively short and very distinctly divided into two portions—muscular and ventricular (Figs. 1, 2, and 3). The identification of the parasite can also be done using polymerase chain reaction technique.
