Local anesthesia for ophthalmologic procedure

Local anesthesia for ophthalmologic procedures refers to the targeted, reversible loss of sensation within the ocular and periocular tissues to prevent pain during diagnostic, surgical, or trauma-related eye interventions Rather than representing a disease, it denotes a clinical state of intraoperative analgesia that affects pediatric and adult patient populations undergoing procedures on structures such as the cornea, anterior chamber, or posterior segment Depending on the specific procedure an...

Local anesthesia for ophthalmologic procedures refers to the targeted, reversible loss of sensation within the ocular and periocular tissues to prevent pain during diagnostic, surgical, or trauma-related eye interventions

Rather than representing a disease, it denotes a clinical state of intraoperative analgesia that affects pediatric and adult patient populations undergoing procedures on structures such as the cornea, anterior chamber, or posterior segment

Mechanistically, local anesthetic agents interrupt neural impulse generation and conduction by blocking voltage-gated sodium channels along sensory branches of the ophthalmic and maxillary divisions of the trigeminal nerve

Depending on the specific procedure and clinical requirements, administration approaches range from non-invasive topical application to infiltrative or regional nerve blocks—such as intracameral, sub-Tenon, retrobulbar, or peribulbar techniques—that can also provide regional akinesia by inhibiting ocular motor nerve transmission
