Characterizing post-anoxic tonic eyelid-opening in individuals


  • Post anoxic tonic eyelid-opening (PATEO) are repetitive, but non-periodic and non-myoclonic movements which are generally presented after 24 hours of cardiopulmonary arrest (CPA).

Why this matters

    Repetitive eyelid opening (EO) after CPA is a rarely reported post-anoxic presentation. Case reports have defined repetitive EO as ‘periodic’ or ‘transient’ with associated post-anoxic electroencephalogram (EEG) burst suppression patterns. However, despite these reports, very little is known about the pathophysiology of these EOs. The results of this study help provide a clearer description and an updated terminology of the under-recognized phenomenon and to further understand its prognostic value.
