The same view with tunnel vision from retinitis pigmentosa.

Retinitis Pigmentosa, or RP, is a genetic eye condition. Generally, night blindness precedes tunnel vision by years or even decades. Many people with RP don't become legally blind until their 40's and 50's and retain some sight all their life. Other's go completely blind from RP, in some cases as early as childhood. Progression of RP is different in each case.

RP combined with progressive deafness is called Usher syndrome.

There is currently no medical treatment for Retinitis Pigmentosa.
