My baby was born with a visible vein under her left eye. It makes her look like she has a perpetual black eye. She's 6 months old know and it hasn't gone away.

Could it be from the high blood pressure I had during my pregnancy? I had preeclampsia and had to have an emergency c-section due to abruption of the placenta? Did this have anything to do with it?

Pediatrician doesn't really give me any answers but he's not worried about it. He thinks it might be less noticeable as she gets older. But to me it looks pretty bad.

Should I worry? Will it fade?
