Recovery from deep coma with roving eye movement: A case report and prognostic review

Roving eye movement (RoEM), commonly seen in unconscious patients with significant cortical dysfunction but without apparent brainstem damage, has unclear prognostic significance. We describe a case of presumed hypoglycemic encephalopathy with RoEM, where the patient emerged from a 4-day coma. While previous reports often associate RoEM cases with poor prognosis, cases with favorable outcomes exist, particularly among young patients or those with reversible conditions. Our findings highlight the variable neurological prognosis of RoEM, suggesting the possibility of improved consciousness and neurological recovery in certain pathologies, thus enhancing our understanding of RoEM's implications.
