Hi,
I have 2 children with the exact same thing. My daughter had surgery to correct the eye muscles at 3 years old and has been wonderful since. Her eyes are perfectly aligned now and she has perfect vision. Before her surgery, she squinted whenever focusing and especially outside in sunlight. She also tilted her head a lot. My specialist said the tilting and squinting was do to the double vision she was having. My son, I noticed the eye wandering out when he was 4 mos old. His was very severe. We did a trial of patching to no avail. His brain was already starting to shut off to the eye (my dr. said if they can blink and the eye stays out during a blink, then the brain is ignoring the eye) he had surgery at 8 mos old and did great initially. Now, at his 1 year check up (we go May 14th) I am noticing his left eye is turned into his nose--the exact opposite of previously. Needless to say, I hate the thought of another surgery, but getting the eyes corrected at a young age is pertinant to them developing normal visual pathways. I have 1 week to wait and see what the dr. sais. He is now 21 mos old. My other daughter is 6 years old with no problems. The surgery is gory (very bloody eyes that are hard to look at and if you go out in public people look at you like you have beaten your child)

The good thing is that it didn't seem very uncomfortable for either of my kids. Sorry you are having to deal with this, but please take it seriously and find a really great dr. that is Key! Any further questions, let me know.
