Dear
Welcome to HCM
We understand your concerns
I went through your details. Your child's problem could be
Exotropia which is the outward deviation of an eye. When the eye turn happens some of the time, but not all the time, the outside observer might conclude that there is no serious problem and fail to seek help. Or they might think the person is simply daydreaming, lazy, or not paying attention. Even worse, without knowing that there is a physical problem, the observer might feel uneasy or mistrustful of the person with intermittent exotropia who gives poor eye contact and comes off as distracted or "shifty-eyed."
Treatment options consist of
Vision Therapy, patching, eyeglasses and/or, very rarely, surgery. The most successful form of treatment is in-office supervised Vision Therapy with home reinforcement. Please consult an eye specialist.
