Foveal Cone Dystrophy

I have not posted in several days because I am out of state with my husband seeing a specialist to try and get a diagnosis for the fact that he is losing his vision and our local doctors, who are very qualified and distinguished, have been unable to determine why. We are dealing with an insurance company that must have failed the Martha Stewart School of Etiquitte. We know God is in control and ask those of you who would to pray for a diagnosis and treatment. The possible diagnosis is something called Foveal Cone Dystrophy, but there are no definitive answers yet.
