It seems like the lens are not responding like they should. It's both eyes that are affected. Prisms don't correct it. Evoked potentials were essentially normal. Retina looks fine.
Eye movements seem to be normal.
One possibility have been a small clot had occurred. Otherwise no one has been able to give me explanation. I have learned to live with it, but try to avoid driving at night as it is more of a problem them. Any imput from others would be appreciated. Thanks in advance.
