My daughter has strabismus...her eye turned out...it started gradually and then became almost constant, but not always turned out, as with amblyopia the turn in or out is constant.
We took her to a pediatric ophthalmologist recommended by our pediatrician. Turns out you need to see a PEDIATRIC ophthalmologist that specializes in strabismus and amblyopia as children's eyes are very very different from adult eyes.
Our daughter who was 2 at the time...was very blessed with no vision loss yet...sense she had no loss of vision patching was not an option (as using patches does not correct the alignment of the eye...but helps strengthen the vision in the eye that the brain has stopped recognizing because that is the only way the brain can stop the double vision...to "turn off" one eye).
Our doctor recommend surgery...I was a bit hesitant but realized that if that was the best way to fix the alignment before she lost vision then we needed to have it done.
So she had the surgery this past January...she did better than I did...she was a trooper...she was 2 years 9 months old...not quite 3 when she had the surgery. We went in knowing that it has an 80% success rate...so I just kinda figured she might need a second surgery...nope first surgery went great. Her eyes are perfectly aligned and she will have her last appointment in December to do a year check up and make sure her vision is still good. She might have to have another surgery around the age of 8 or 9...sometimes the condition will show up again at that age...but we will cross that bridge when it comes.
My advice and you can send me a private message if you want to...make sure you see a pediatric specialist...our doctor only works with strabismus and amblyopia...and if they recommend surgery don't be afraid...I would have her have the surgery again in a .heartbeat. If there is a vision loss already make sure she follows the patching instructions and using her glasses as directed...that can really increase her vision in the bad eye. My doctor told me that eye exercises were really not an option to help correct my daughter's eyes.
Big hug to you and your family...it is scary, but fixable!!
