Ocular angiostrongyliasis in a child--first case report from India.

A rare case report of Angiostrongylus cantonensis (rat lung worm) from the eye is presented here. This worm generally causes eosinophilic meningo-encephalitis and accidentally infects humans by ingestion of uncooked snails, slugs, frogs etc. The child was presented to us with diminished vision in left eye. Slit lamp examination showed an actively motile worm in the anterior chamber. Surgical extraction of the worm was performed and it was identified as A. cantonensis. This is the first case of ocular A. cantonensis infection from India with no signs or symptoms of meningitis. After surgery, the visual acuity of the patient returned to normal.
