It's something to do with the fact that having sickle cell anaemia reduces the chances of contracting malaria, obviously a very common disease in Africa. I'm not quite sure what the link is but hopefully this helps a little bit?
Progressive degeneration of the retina that affects night and peripheral vision is known as retinitis pigmentosa.
<h3>
What is retinitis pigmentosa?</h3>
- A collection of uncommon eye conditions known as retinitis pigmentosa affect the retina.
- 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.
