  • Title: Orbital regional anesthesia.
    Author: Fanning GL.
    Journal: Ophthalmol Clin North Am; 2006 Jun; 19(2):221-32. PubMed ID: 16701159.
    Abstract:
    Orbital regional anesthesia is a useful and safe modality for providing excellent operating conditions for the surgeon and painless, pleasant circumstances for the patient. It is especially suited for patients who are extremely sensitive and who could not tolerate topical anesthesia or a sub-Tenon's block without deep sedation. Both intraconal and extraconal techniques can be used safely and effectively if proper precautions are taken to enter the safest areas of the orbit and to avoid the vascular areas and the deep orbit where structures are tightly packed and thus more easily harmed. Thorough knowledge of orbital anatomy and understanding of the globe-orbit relationship of every patient are necessary to perform this form of regional anesthesia. In addition, knowledge of the effects and side effects of the anesthetics and adjuvants is also required.
