Ophthalmic Complications of Locoregional Anesthesia in Dentistry

Local and locoregional anesthesia (LRA) are extensively used for performing painless intraoral procedures. In rare cases, ophthalmic complications such as diplopia, blepharoptosis, mydriasis, etc., may occur. In general, symptoms disappear hours after the injection and rarely persist for a prolonged duration. The aim of this paper is to emphasize the ophthalmic complications that may occur after intraoral anesthesia injection in dentistry.Symptoms, management and prevention of the most common ophthalmic complications related to intraoral local and/or LRA anesthesia are reviewed. Despite being uncommon, ophthalmic complications may happen and lead to stressful situations. Dentists should be aware of their causes in order to prevent them.
