Isolated optic nerve oedema as unusual presentation of electric injury.

A 45-year-old man with no significant medical history presented following an electric current injury (380 V). He developed multiple systemic injuries including third degree burns and after 1 week of hospitalisation he reported unilateral visual changes. Examination suggested the presence of optic nerve oedema without evidence of haemorrhage, exudate or vessel abnormality. This was considered to be related to the electric shock. A trial of corticosteroids was considered. He was followed up to 5 months in clinic and was noted to have developed unilateral optic atrophy and no other systemic manifestations. Initial and 5 months follow-up optic nerve colour photograph and optical coherence topography were documented. The present case highlights the fact that electric current injury can present with only a unilateral ischaemic optic neuropathy, the need for early diagnosis for timely treatment and the controversial role of corticosteroids. 2014 BMJ Publishing Group Ltd.
