John Wenberg's Retinitis Pigmentosa Page Retinitis Pigmentosa is an eye disease that affects a person's night vision and peripheral vision. It is a genetic disorder that is usually hereditary.
Symptoms start with decreased night vision and later progress to a diminishing of peripheral vision.
The rate of decline varies depending on the genetic makeup of the disorder and also varies somewhat in individuals. Usher Syndrome affects the eyesight in a manner similar to Retinitis Pigmentosa but also affects the hearing. Macular Degeneration affects the center of the Retina and is a leading cause of blindness among people over 55, though young people can be affected by the disease as well. All of these diseases affect the Retina and are usually lumped under the general category of Retinal Degeneration. Please enter your email address in the form below.
