[Complications following temporary occlusion of the nasolacrimal duct with tissue adhesive (Histoacryl)].

This paper presents 4 cases in which the punctum had been temporarily occluded with tissue adhesive, still showing toxic tissue reaction years later. Abscess, dacryocystitis, dacryocystitis with dacryolithiasis, dacryocellulitis and polyposis were found. In the light of these findings and the relevant literature-especially with regard to late injuries-it is not advisable to use tissue adhesive, at least not for the purpose of punctal occlusion.
