20. Signs of RP usually appear during childhood or adolescence. The
first sign is often night blindness followed by a gradual loss of
peripheral vision. As the disease develops, people with RP may
often bump into chairs and other objects as peripheral vision
worsens and only central vision persist. They see as if they are in a
tunnel (thus the term tunnel vision).
