Hemianopsia - Definition


Hemianopsia is the impairement, or even loss of vision in one part of the field of vision. It can affect the outside or inside areas of the field. It can also sometimes affect only one eye, or both in cases of loss of the outside area of the field. It is primarily caused by a lesion on the optic pathways, which can be the result of a number of different causes, including cranial trauma, abnormality in the cerebral blood circulation, or compression due to a tumor. It is possible to regain the lost sight if the affected person is treated quickly.
