natka813 [3]

Progressive degeneration of the retina that affects night and peripheral vision is known as retinitis pigmentosa.

<h3>What is retinitis pigmentosa?</h3>

  • Retinitis pigmentosa causes the retinal cells to gradually deteriorate over time, resulting in visual loss.
  • RP is a hereditary condition that affects people at birth.
  • The term "retinitis pigmentosa" (RP) refers to a group of illnesses that affect the retina's light-sensitive cells and impair vision.
  • There is currently no medication to stop the course of the disease, nor is there a cure.
  • Night blindness and tunnel vision are symptoms.
  • Retinitis pigmentosa has no specific treatment.
  • However, using UV sunglasses to protect the retina in your eyes may help postpone the onset of symptoms.
  • For people with very advanced disease and severe visual loss, a retinal prosthesis (artificial retina) has been developed.
