See a pediatric ophthalmologist Eye MD. They have lots of training and experience in getting children of all ages including infants to coopeate with treatment.
Thanks for your valuable suggestions.
I have undergone his detailed examination with a ophthalmologist.
She clarified that vision in both the eyes is normal and no need of any glasses this time.
Both the eyes have +.5 distortion which is normal in this age as per her knowledge.
Now what i have to do to correct his intermittent exotorpia.
Often intermittent exotrophia requires no treatment unless it is becoming more common and the eyes are turned out more than straight at which time eye musucle surgery is often recommended. Not every case requires surgery.
