Question

 

 

 

Hello,

I have some problem in both my eyes.I think it is from birth.but I am not sure.

My symptoms are:

I can not see in dim light.I mean if there is less light around me then I am not able to see any object properly but if the same object is placed at same distance in proper light then I can see it very very clearly.

I went to many doctors.They checked my eyes and came to a conclusion that there is some problem with my retina.The cones or rods(i don't know which one or both) are less from birth.

They checked for my eye glasses but all in vain.They all said that the natural lens is perfectly fine.


One of the doctors also showed me Ishihara chart.I identified some of the numbers but couldn't identify others.

Please help me and tell me what is wrong with my eyes.Is the disease permanent ??? And is it going to get worse in the future???

 

Please help me...

Thanks in advance....:)

Thanks for your Question
 
What you have is called Night Blindness or Nyctalopia. The most common two heridatory diseases that cause night blindess are Retinitis Pigmentosa and Congenuital Stationary Night Blindness (CSNB). Both of these diseases affect the Rod Photoreceptors which are responsible for night vision. Another common cause of night blindness is deficiency of Vitamin A.
 

Vitamin A deficiency can be diagnosed by blood test and it is treatable.

Congenital Stationary Nigh Blindness is non progressive condition and on ocular examination, the retina appears normal. It can be diagnosed with clinical history and Electroretinogram (ERG).

Retinitis Pigmentosa is a progressive disease and its severity depeneds on the type of inheritence in which autosomal dominant type has good prognosis which X-Linked form has the worst prognosis.In ocular examination there is black pigmentation on retina (Which is called Bone Spicules), pale optic disc and attenuation of retinal blood vessels. It is also associated with macular edema,cataract and keratoconus.

Unfortunately, there is no treatment for Retinitis Pigmentosa. Treatment depends mainly on cataract removal,kertoconus and macular edema treatment,otherwise there is cure for it.

There are certain oral supplements that can be used to slow down the progression of the disease. To read more about these oral supplements, Click here.

You should discuss these things with your eye doctor and you have to know the exact diagnosis of your condition because you might have other types and causes of night blindness which can be treatable.

Good luck
