—We wish to thank Mori et al for their observations and comments concerning the association of transient eye opening with EEG suppression-burst pattern in severe anoxic encephalopathy. There are ten cases of this phenomenon with which we are personally familiar—all with rapidly fatal outcomes. The presence of a survivor with this phenomenon is most interesting, especially in view of the EEG transition to another pattern of poor prognosis, ie, a generalized periodic pattern reminiscent of Creutzfeldt-Jakob disease (although this pattern is often associated with myoclonus in the postanoxic patient). The prognosis in these patients is most likely related to the severity of the anoxia, and the suppression-burst pattern is merely a reflection of this severe metabolic insult. Prior1 predicted approximately a 92% mortality with the suppression-burst pattern after cardiopulmonary arrest. Other authors, including Kuroiwa et al,2 also suggest a very high mortality (approaching 96%) in patients with suppression-burst
