Boosts other senses: The brain pays more attention to hearing, smell, touch, etc. When deprived of sight.

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. ...Read more

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

If the visual nerves in the brain are disturbed by stroke, or vascular changes, tumors or some congenital anomalies, there can be field defects. But the defect depends upon the size of the optic nerves impacted. So a large lesion might have minimal visual disturbance in some cases. ...Read more
