First of all, how do you really know that this "doctor" knows what she's talking about? I mean is it just cuz she is articulate? Maybe because she speaks with confidence? Well, just because someone is a doctor that doesn't automatically mean that they know what they're talking about.
Next, I guaren-frickin-ty you that she doesn't have a degree in steroids and only knows of them through random "doctor selected reading", that is besides the ones that are legally prescribed like cotisone and shit like that. To be totally honest with you most doctors know less about steroids than alot of people on this board.
If you really want talk to someone who knows just about everything there is to know about steroids then go talk to a professional football trainer or doctor.
Now, whether or not they can make you go blind, this question has never been medically answered and probably never will be. You'll just have to take your chances.
