  • Title: Nitrous oxide inhalation anaesthesia in the presence of intraocular gas can cause irreversible blindness.
    Author: Lockwood AJ, Yang YF.
    Journal: Br Dent J; 2008 Mar 08; 204(5):247-8. PubMed ID: 18327188.
    Abstract:
    Nitrous oxide inhalation sedation is frequently used in dental and other surgical procedures. We report the case of a patient with intraocular gas who developed sudden elevation in intraocular pressure and blindness as a result of nitrous oxide anaesthesia. All medical and dental personnel administering nitrous oxide inhalation should be aware that this is contraindicated in patients with intraocular gas.
