Retinitis Pigmentosa
Retinitis Pigmentosa may be a genetic retinal disorder. during this condition the photoreceptors; Rods and Cones present within the Retina progressively breakdown over a period of your time , leading to loss of vision.
In most cases it often begins with decreased night-sight and loss of peripheral (side) vision.
If the cones, especially within the Macula (centre most a part of the retina) breakdown, chromatic vision also can get affected in some cases as cones help in detecting color.
Although the moderation of RP may differ from person to person. RP also can eventually cause blindness.
Symptoms of Retinitis Pigmentosa
Symptoms of RP usually start becoming noticeable during the primary or second decade. Few symptoms that are often seen are:
* Difficulty in driving, reading, recognizing faces or objects
* Peripheral (side) vision loss
* Central vision loss (Focusing on objects becomes difficult)
* Difficulty in seeing in the dark (night vision loss or night blindness)
* Sensitivity to sudden flash of sunshine (light-sensitivity also referred to as ‘photophobia’)
* Problem in Color Identification
As the disease is genetic i.e. it's passed on to the youngsters from their parents, it also can develop during childhood or teenage. However, it's going to vary counting on the genetic factor.
Causes of Retinitis Pigmentosa
Retinitis Pigmentosa is genetically caused (runs in families). it's not an acquired eye disorder i.e. it's not caused by any external damage to the attention .
As per recent research, there are 3 ways on how the mutation within the genes can damage the retinal cells and cause RP:
Autosomal Recessive Retinitis Pigmentosa
Autosomal Dominant Retinitis Pigmentosa
X-Linked Retinitis Pigmentosa
Autosomal Recessive RP:
Autosomal Recessive RP means the faulty (the gene isn't producing enough protein for the retinal cells to function normally) gene can cause this disorder to the kid , if it's transmitted by both parents. there's usually a 50% chance that it'll be passed on to the kid .
Autosomal Dominant RP:
Autosomal Dominant RP means the gene that carries this disease is usually passed on to the kid by just one parent.
sometimes thanks to mutation (changes within the genes), RP can arise albeit the person doesn't belong to an equivalent family.
X-Linked RP:
X-Linked RP means the gene on top of things of RP is found on the X chromosome .
Men contain one X chromosome while women contain two X chromosomes. Hence, RP affects men and ladies during a different manner.
In most cases, faulty genes on the X chromosomes are often directly associated with RP.
