The condition you describe is known as esotropia. There are several types of esotropia, which depending on the specific characteristics of her esotropia, can be correctable with glasses or may require surgery. An ophthalmologist specialized in pediatrics and strabismus can perform the appropriate tests to determine how to proceed so I would definitely have her evaluated as soon as possible.
Thank you.
She is being evaluated tomorrow first by her pediatrician who has been aware of this problem since she was born so we will go from there =)
