Retinitis Pigmentosa
More than 100,000 Americans are affected with one of a group of progressive night-blinding disorders collectively known as retinitis pigmentosa (RP). Night blindness refers to difficulty seeing in the dark; it is the initial symptom of RP and usually occurs within the first two decades of life. Within the third decade most patients will also experience some impairment of peripheral, or side vision, which in the majority of instances progresses to a profound loss. In addition, about half of all patients with RP will have variable degrees of cataracts.
