Definition:

Diagnosis:
Hemianopia can be diagnosed by vision tests and optometric examinations.
Treatment:
There is no exact treatment for the hemianopia. Magnifiers and optical devices can thus be used to improve vision.
Symptoms and Signs:
The signs and symptoms of hemianopia are loss of half of one's vision, reduced night vision, and the need for more light in order to see properly.
Causes:
Hemianopia is a result of damages done to the optic nerves. This can be acquired through brain injuries, tumors or stroke. Blood clots and capillary damage can also contribute to this condition.
