Complications of Periocular Dermal Fillers.

Dermal fillers, in particular hyaluronic acid gel (HAG) fillers, are used in the treatment of aging changes in the periocular area. Filler treatment requires in-depth knowledge of specific issues relating to product performance and administration, safety protocols, and recognition and treatment of complications. There are different approaches to treatment of the tear trough. Prior filler treatment must be suspected in patients presenting for aesthetic evaluation, and the possibility of migration with a dysmorphic appearance and/or Tyndall effect appearance always is kept in mind. Treatment with hyaluronidase injection generally is effective in reducing overcorrection or migration of HAG in this area.
