Anesthesia for Ophthalmic Procedures in the Standing Horse

Summary

# Editorial Summary: Anesthesia for Ophthalmic Procedures in the Standing Horse Maintaining horses in a standing, sedated state for ophthalmic work offers significant advantages over general anaesthesia—reducing recovery risks, minimising cost, and preserving the animal's airway reflexes—yet requires practitioners to master precise local and regional anaesthetic techniques specific to equine orbital anatomy. Labelle and Clark-Price examined the anatomical basis and clinical application of local anaesthetic delivery methods for standing eye procedures, emphasising how accurate knowledge of neurovascular landmarks and fascial planes underpins both diagnostic and surgical interventions. Their analysis demonstrates that properly executed regional blocks (including auriculopalpebral, infratrochlear, and retrobulbar techniques) can provide complete desensitisation sufficient for everything from routine ophthalmic examination through to therapeutic corneal procedures and surgical repair. For farriers and equine healthcare teams, understanding these techniques—particularly the anatomical considerations that vary between individual horses—translates to improved safety margins during standing procedures and reduced reliance on general anaesthesia in patients where systemic risk is a concern. This work underscores that competence in equine ophthalmic local anaesthesia should be considered foundational knowledge for any practitioner involved in standing surgical or diagnostic eye work.
