1. Retinitis pigmentosa is a progressive disease
2. Speed of progression varies from person to person. I have seen patients going bling at young age of 30 years and I have seen patients having good vision even at age of 50 yrs. So, you can go for 6 months perimetry test and that will guide you the rate of progression.
