Please go see another doctor. If you have photo proof of her eyes being different in flash photography (ie, one is dark and one is typical red eye) take it with you to the next doctor you see. Then there could be something inside the eye blocking the retina (which flash off the retina causes the red eye effect in photos) and you need to find out why immediately.
If could be nothing or something.
But definately see another eye doctor. Contact a LASIK center as those doctors are much more specialized and they may not see your daughter, but they may be able to refer her to someone. If all else fails call the specialty childrens' hospital in your area and find out who their eye specialist is and get an appointment.
I hope it goes well for you.
