Objective To identify the clinical significance of epileptic eye movement for localization of posterior epileptic seizures. Method sThere were 12 posterior epileptic patients, who were undertaken the detailed presurgical evaluation and ictal SEEG recording, and the epileptogenic zone of whom was confirmed restricted within posterior cortex through the boarder of epileptic cortical resection and the result of epileptic surgery, included in the research. Result sThe cluster analysis of posterior cortical area of interest showed that parieto-occipital sulcus (POS) with the adjacent cortical areas belonged to the Medial Group; intraparietal sulcus (IPS) with the adjacent areas belonged to the Intermediate Group; and the Lateral Group included anterior occipital sulcus (AOS) and posterior temporal cortex. Eyes forced stare had the significant correlation with IPS, POS and related cortical group. Contraversive eye deviation had no significant correlation with cortical eye field with the related cortical areas. Conclusion sForced eye stare was significant eye movement in posterior epilepsy, and had significant correlation with IPS and POS. Ipsiversive eye deviation and convergence binocular movement were rare semiology in posterior epilepsy, and AOS had significant correlation with the two type of epileptic eyes movement.
