AbstractNitrous 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.
