Abstract: The impairment of posterior visual pathway, caused by cerebrovascular disorder, brain tumor or injury, is frequently occured in clinic. The homonymous hemianopsia or quadrantanopsia presents in most of those patients, which are usually neglected by eye doctors for a long time. Recently, with the development of the diffusion tenser imaging （DTI） and functional magnetic resonance imaging （fMRI）, it can be diagnosised more easily. We suggest that it should be treated with proper medication to decrease primary and secondary impairments of visual pathway in acute stage combined with visual restoration training in late stage.

Key words: posterior visual pathway diseases/diagnosis, vision restoration training
