Terson's syndrome is one of the cerebro-ocular syndrome which entails the findings due to intraocular hemorrhage in association with increased intracranial pressure following subarachnoid hemorrhage. We reported a patient suffering from total blindness after basal ganglia hemorrhage, who was diagnosed as Terson's syndrome and vitrectomy was done. Our patient recovered normal visual acuity after vitrectomy, which fascilitated rehabilitative process. We alsoperformed diffusion tensor tractography to investigate abnormalities of brain related to the visual dysfunction, which revealed decreased orientation and integrity of the right optic radiation. It is important to diagnose Terson's syndrome early because it is one of the cerebroocular syndrome which needs early intervention with consideration of the integrity of optic pathway.
