Concretions due to actinomyces may occur in the superior or in the inferior canaliculus.

If the inferior canaliculus is involved, the first symptom is epiphora. There may be a slight swelling in the region of the canaliculus and dilatation of the punctum lacrimale (fig. 1). In early stages, however, these signs may be absent or so slight that they may be easily overlooked and a diagnosis of stenosis of the lacrimal passages made. On syringing the tear sac, there is no interference with the passage of fluid to the nose. On pressure in the region of the canaliculus, a droplet of pus appears at the punctum. In later stages the swelling of the canaliculus is noted at first sight, the ectasia of the canaliculus being considerable (fig. 2).
