How quickly does RP progress?
“Every year I lose a little bit of vision, and every year I do some adjusting,” notes Tom Tarrant, who describes himself as “still having a lot of useable vision,” although he is legally blind. While gradual vision loss is the common feature of almost all forms of RP, there is no predictable rate of loss, even for people in the same family. Usually the progression is quite slow. Vision sometimes appears to remain stable between annual eye examinations.
