Nasolacrimal Duct Obstruction Following Hyaluronic Acid Rejuvenation of the Tear Trough.

Although generally safe, hyaluronic acid rejuvenation of periorbital tissue has been reported to cause minor and major adverse events. The authors document a case of nasolacrimal duct obstruction due to hyaluronic acid rejuvenation of the tear trough. Nasolacrimal duct obstruction immediately resolved following irrigation of hyaluronidase into the affected lacrimal system. To the authors' knowledge, this is the first reported case of nasolacrimal duct obstruction due to filler injection.
