Local anesthesia is a common technique used to provide anesthesia for ocular surgical procedures. Despite improvements in operative conditions, there is still the potential for complications, both local and systemic, during routine procedures. This article discusses the physiology of neuronal function, the chemistry of various local anesthetic agents, and the pathogenesis of toxicity. It is vital for the practitioner to have thorough knowledge of these subjects in order to reduce risks when performing ophthalmic procedures.

D000772	Anesthesia, Local	A blocking of nerve conduction to a specific area by an injection of an anesthetic agent.	Anesthesia, Infiltration,Local Anesthesia,Neural Therapy of Huneke,Huneke Neural Therapy,Infiltration Anesthesia
D000779	Anesthetics, Local	Drugs that block nerve conduction when applied locally to nerve tissue in appropriate concentrations. They act on any part of the nervous system and on every type of nerve fiber. In contact with a nerve trunk, these anesthetics can cause both sensory and motor paralysis in the innervated area. Their action is completely reversible. (From Gilman AG, et. al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed) Nearly all local anesthetics act by reducing the tendency of voltage-dependent sodium channels to activate.
