Retinitis Pigementosa (RP)
  • RP refers to a group of inherited disease causing retinal degeneration.
  • Retinal degeneration
symptoms
Symptoms
  • Decreased vision or in low light
  • Loss of side (peripheral) vision, causing “tunnel vision”
  • Loss of central vision (in advanced cases)
causes
Causes
  • RP can run in families
  • Disorder can be caused by genetic defects
  • Cells controlling night vision are called “rods”
  • Retinal cone cells are damaged the most
exams and test

  • Refraction test
  • Retinal Photography
  • Side vision test (visual field test)
