I've had double vision for about 15 yrs. Initially I thought it was caused by either :
a) Carbamazaphine Retard (side effects)
b) Iritis ( the pupil became attached at an odd angle)
This week I was told it was caused by Ataxia.
Since the onset of double vision, the pupil in my left eye has gradually
worked inwards towards my nose, being classified as a Squint.
I've just had surgery, the surgeon put adjustable stitches into the eye
muscle and then tweaked them until single vision came into focus
Up till now I've had to have glasses with a very strong prism. I found
that when walking, Nystagmus made my pupils seem to bounce against
the prism, causing balance to become harder to control. In fact I
actually felt disorientated, perception of depth was more difficult.
But on the whole prisms are essential if you still want to drive, the alternative
would be an Occlusal Contact Lens in the effected eye.
It's going to take around 6wks for the eye to recover from surgery but
already I'm experiencing an amazing transformation. xB
