The neuronal basis for diplopia following local anesthetic injections.
The case report presented here describes a situation in which diplopia resulted as an effect secondary to maxillary infiltration anesthesia. Prior cases and theories regarding the mechanisms involved are reviewed, and a new theory explaining this phenomenon is proposed. The autonomic nervous system is presented as the logical basis for the untoward systems, rather than simple circulation of anesthetic solution in the vascular tree.
