Retinitis pigmentosa
Nature
Retinitis pigmentosa (RP) is commonly diagnosed during childhood or young adulthood. Night blindness is the first symptom of RP, followed by increasing loss of peripheral vision. Children with Usher syndrome are born with varying degrees of deafness and later develop retinitis pigmentosa (RP). Although there is not yet a cure, researchers have identified vitamin A supplements as a treatment to slow the progression of retinitis pigmentosa.
