Welcome to our family. I see that you've already been welcomed and cared for by our members. I just wanted to make sure that I added my welcome to the ones you've already received.
I am sorry to hear about the Plaquenil retinopathy suffered by you wife, especially since (as you say) it could have been avoided. Are you taking Plaquenil for your lupus?
I am sure that you will get the hang of using these forums. You are already making a very good start. I am glad that you are here.....Welcome again.
Peace and Blessings
Look For The Good and Praise It!
