If you were given a dye, you had a Fluorescein Angiogram. It helps them better see the veins and if there is any bleeding / leaking ... it's a common test. The only risk here is the dye itself, some may have allergic reactions to it.
I was given an injection that contained a dye. I had no bad effects. Was this standard procedure?
