R.S.
Okay the doctor who said it would clear on its own was full of sh*t. The pediatric ophthalmologist was telling you the truth, surgery is usually the way to go with these issues. My daughter has surgery to correct her intermittant exotropis and strabismus right after her third birthday.
Which doctor told you that it hardly effects his vision? Because eventually the the brain will stop reading signals from the wandering eye and he will no longer see out of that eye. This then means the child has no depth perception. The brain cannot handle the double vision that is caused by the eyes not being aligned.
It used to be though that exercises could fix this issue...my step sister went this route and her eye still turns out if she gets tired and is not concentrating on keeping them aligned.
My daughters surgery went perfectly and her eyes are beautiful and straightly aligned. I too was totally against surgery but after doing my homework on line and talking with our pediatric ophthalmologist...my husband and I realized it was the best way to fix it
If you want to message me I know a lot about this topic, as when you have a child with this (it is totally a genetic thing, runs though our family) you learn the lingo and all your options.
I spotted the condition in a friend's child when she was about 9 months old. My friend got really mad at me when I mentioned it and said her pediatrician told her her daughters eyes were just fine. I was just seeing it everywhere because my own daughter had it. Over two years later it was actually diagnosed and her daughter had lost vision in one eye and is now having to wear thick glasses and patching the good eye to try and regain vision. That might have been prevented with an earlier diagnosis.
Get a second diagnosis, but do not wait around on it. Sending you a huge hug!!
