<<Disclaimer: Verify this information before applying it to your situation.>> I had to have a flourescent angiogram to check bleeding in my eye due to diabetic retinopapthy--all those years of being celiac which thru off my blood sugars (I am diabetic) etc, have caught up with me. The problem with the dye, which they swore was safe and gf (a big HA), was that of course, I had a gluten reaction. Anyone know of any safe, gf flourescent dye in case I need that tool again? By the way, a word to the wise, since our systems have been compromised, a very good idea is to go to an oprthomalagist on a regular basis (as opposed to an optomitrist). My problems were picked up only when the eyes were dilated. I'll summarize and share the wealth Thanks Ann
