With patients like yourself - every little bit of vision is so very important. I understand that completely. I don't know all your specific details - but I can tell you are troubled with these recent changes. All I can tell you is that you need a compassionate AND skilled ophthalmologist to work with you to determine if there are any new problems and anything that can be improved or fixed. Now if there is nothing that can be physically improved through medications or laser or surgery - then you will need to simply make the most of what you have through low vision training, low vision glasses and magnifiers, low vision reading machines, and adaptation. Please don't feel like a fool. If your doctor doesn't give you a worthwhile evaluation and at least listen to you - then find one that will.
