Retinitis pigmentosa has an earlier and more serious effect on rod cells or on cone cells?

Answer 1

Retinitis Pigmentosa or RP, is a general name given to several similar conditions that result in the slow, progressive loss of photoreceptors. There are many different forms of RP, but the most typical forms effect the rod cells - those used for night and peripheral vision - first and as the disease progresses the cones - centeral acuity - are also lost restultung eventually in near total or total vision loss. There are some forms of RP that will progress differently and the rate of vision loss varies dramatically.

Answer 2

Retinitis pigmentosa primarily affects rod cells, which are responsible for vision in low light conditions and peripheral vision. As the disease progresses, cone cells, which are responsible for color vision and high acuity, can also be affected, leading to further vision loss.
