Hi Dan, and welcome to the group!
 I posted on an earlier thread...but didn't realize that you were in fact diagnosed with retinopathy.  Have you undergone laser treatments?  If the laser has caused scarring, there is a surgery called a vitrectomy, which removes some of the blood from the vitreous humor (the liquid part inside your eye).  That surgery can help remove some of the "floaters" and secure a patially detached retina.  I hope your doctor has discussed these options with you.  I have been through many MANY procedures on my 
 eye(s).  As I said in my other post, feel free to e-mail me if you want more info about the surgeries and what I went through with the eye problems.  My addy is listed.  Nice to meet you, and good luck!  sheryl
