I saw the optho-neurologist yesterday. For over four years my vision has been a real issue, with excessive eye-strain, light sensitivity, and double vision. All of the symptoms fluctuate, with no predictable pattern. It has been quite disabling and exhausting. I've seen an opthomologist, several neurologists, and finally was given a referral to see an opthoneurologist.
After a lengthy exam the doctor concluded that I have a congenital vision defect - have had it all my life - which splits my vision and distorts what I see. When I was a child I noticed that my vision would split, and I just thought it was a consequence of daydreaming. I'd 'pull it back together' by jolting my head and correcting it. However, as I age my brain cannot self-correct the image. Contributing factors are fatigue or exertion, excessive light, noise and intensity.
It has become increasingly troublesome now, as the splitting (double images) is not only double vertically, but also angles sideways. It is all askew, patterns superimposed on each other, in such a garbled image that it is exhausting. The fatigue that results impacts not only on my life, but on my brain.
Too much light, even with sunglasses, has caused blurred vision. It improved immediately when I put pinhole glasses on - glasses that block most of the light coming through. What I need is not dim light, but a small amount of really good light. When the image is crisp, the brain processes more efficiently.
The good news is that all of this can be corrected. The light sensitivity is due to cataract surgery and implants, but the disordered vision can be corrected by prism lenses and eye exercises to help strengthen the muscles. If that doesn't work successfully within a year, a simple surgery can be done on the muscles affecting both eyes which would restore the correct muscle tone. This surgery is routinely done on infants who have muscle problems affecting their eyes at birth.
The optho-neurologist also reviewed my brain scan, moving my skull images all around, from every angle. It was fascinating! He said my brain, eyes, and blood vessels are all healthy.
I'll be wondering what I'll look like - will I be wearing pinhole glasses and prisims? One way or another, I'll be wearing something, as my current vision needs an upgrade, even with my interoccular lens implants. And, I'll keep wearing my visor, even in the house, to cut the glare!
