The 4 Categories of Blindness

Contrary to popular perception, there is a spectrum of different types of blindness.  Some people are completely blind, while others may be able to see some lights, shapes, or nearby objects.  The cause of blindness could stem from the eye or the brain.

Here are the 4 key types of blindness:

1. CVI, or cortical/cerebral visual impairment, is the leading cause of modern day blindness in children.
2. Retinitis pigmentosa is a genetic disorder, which affects up to one in 4,000 people in the U.S.
3. Macular degeneration is another one of the leading causes of vision loss, affecting an estimated 10 million people in the U.S.
4. Retinopathy of prematurity is an eye disease which occurring in babies born prematurely.
