How do visual impairments affect the brain?

In brief: Boosts other senses
The brain pays more attention to hearing, smell, touch, etc.
When deprived of sight. These senses do not actually improve; when tested objectively blind people don't "hear better", but the brain can certainly pay much closer attention to the information. It would be very hard to read braille were this not the case.
