How does retinitis pigmentosa allow someone to lose their peripheral vision?

ANSWER

Retinitis Pigmentosa (RP) is a genetic disorder that damages the retina, the part of the eye that senses light. Night blindness is one of the first symptoms. You might also have a hard time telling different colors apart. Over time, you’ll notice changes in your peripheral vision. You can get this condition at any age, but it usually strikes teens and young adults. Most people who have it are legally blind by age 40.
