Some causes of swelling of the retina are very difficult to diagnose or are "idiopathic" which means the cause is unknown. You could ask your present eye MDs for a second opinion, or seek out a retinal specialist on your own for another opinion.

Thank you for your reply. Our MD said the same as you.It all seems so complicated .i dont think we could benefit from a second opinion as we have seen all the eye doctors in our area and they all say the same and pass us on.So i guess he'll have to stay a guinipig for a while! Thank you for your time and advice yours sincerely meeshwa
