My 12 year old daughter developed intermittent exotropia in

Patient: My 12 year old daughter developed intermittent exotropia in her right eye 2 months ago. It has been happening increasingly since I first noticed it. Her optometrist referred us to a specialist who we are waiting to see. Should I be concerned that the strabismus is a sign of an underlying health problem? The optometrist thinks not, she said she has probably always had it and I just never noticed. I would have noticed.
