Nocardia asteroides canaliculitis: a case report of uncommon aetiology.

Ocular nocardiosis is an opportunistic infection and is believed to be a rare entity. We describe a rare case report of a patient with culture-positive Nocardia asteroides canaliculitis who presented with complaints of watering, purulent discharge and painful swelling of left lower eye lid. A purulent tenacious material was expressed from the punctum of lower eye lid and subjected to microbiological investigations such as smears and cultures. Smears and culture proved the presence of Nocardia asteroides in the sample collected from punctum.
