Brazilian Rainbow Boa eye-cap problem...

I have a 4 year old Braz. rainbow boa and she's got a serious eye-cap
problem. They're dimpled in, like a dent in a soda can you can't get
out. I've had her for about a year and no matter how many times she
sheds the dents do not come out. Otherwise she's a healthy snake, no
probs shedding, eats like a horse, very tame (my sweetest snake
actually) it's just her eyecaps. A vet (HA!) gave me some ointment
when I first got her but it did no good.
Any ideas???
