Abstract: Objective: To analyze clinical features and surgical outcome of intractable occipital epilepsy and introduce surgical experience. Methods: 20 surgical treated occipital lobe epilepsy cases were studied retrospectivelyt, the patients general clinical data, seizure features and surgical outcomes, and conclude surgical experiences of those patients. Results: There were 18 cases （90%） under general tonic-clonic seizures, 13 patients （65%） with lateralizing value or semiology of ictal limb posturing, 17 patients（85%） with abnormal CT/MRI images, 8 cases with vision auras; Epileptogenics were located unilateral occipital lobe in 14 cases（70%）, unilateral temporo-occipital lobe in 5 cases（25%） and bilateral in 1 cases.13 cases were treated by lesionectomy and focal resection, 4 cases by amygdalohippocampotomy, 1 by corpus callosotomy.All patients were treated by multiple subpial transection （MST）.Surgical result included 16（80%） satisfactory cases, 3 （15%） notable improvements, 1 （5%） good case. Conclusion: Intractable occipital epileptic patients always had abnormal MRI image, general tonic clonic seizure with unilateral severity sign, more vision auras and good surgical outcome.
