Is it true that the bigger the visual field defect, the worser the brain has been damaged?

Depends: If the area of the brain damaged is the occipital lobe or the optic radiations, then visual field defects can occur. Generally damage at its maximum occurs immediately and over time there can be a lessening if the areas recover. Of course, the larger the initial damage, the more changes will be detected. Your neurologist can help sort this out.

Is it true that the bigger the visual field defect, the worse the brain is actually damaged?

Yes and no: A visual field defect doesn't have to occur from brain damage. For instance a detachment of the back of the eye(retina) can cause a visual field defect. However, if the cortex of the back part of the brain is damager(occipital lobe of brain) thden the more damage, the worse the eye symptoms.
