What is a primary concern when injecting local anesthetics near the eye?

Injecting local anesthetics near the eye presents a significant risk of intraocular injection, which can lead to severe complications. The proximity of the eye to the injection site means that there is a heightened chance of the anesthetic inadvertently entering the eye itself. This can cause serious issues, including damage to intraocular structures, subsequent vision problems, or even permanent loss of vision.

Considerations such as damage to retinal tissue or intraocular pressure increase highlight the critical nature of precision in this area. Given the sensitivity and vulnerability of ocular tissues, even a small misstep in administration can have dire consequences, making the understanding of this risk paramount for practitioners interacting with periocular regions.

While allergic reactions can occur with any drug, including local anesthetics, they are generally less frequent and can usually be managed effectively. Similarly, while some might assume that local anesthetics could trigger migraines, this is not a primary concern linked directly to the procedure of injecting near the eye. Prolonged anesthesia is also a potential side effect of local anesthetic use, but it does not represent an acute risk in the same way that an intraocular injection does. Thus, the potential for severe complications from an inadvertent intraocular injection stands out as a key concern in this scenario
