The term used for it is Amblyopia and I think both kids should be seen by an eye specialist rather than just the family doctor so that the best course of treatment can be determined, especially for the 8yr old because the younger treatment begins, the better the outcome. From your description, his sounds more severe than hers.
The glasses are the first line of treatment typically tried. If there isn’t enough improvement then they go to patching the good eye for anywhere from 2–6 hours per day to really force the other one to work.
Years ago, I was a regular babysitter for a family with a four year old boy with a pretty severe case and they wanted to get this corrected before he started school so that it wouldn’t adversely effect his learning to read.
For about six months he was wearing the glasses with one side patched for several hours per day because just the glasses alone weren’t showing any more improvement.
(That’s the main reason I’m suggesting the kids be evaluated by an eye specialist because they can assess the initial severity and also do continual testing to keep track of progress.)
With this little boy, the eventual decision was to finally do corrective surgery because it apparently reached the point where even the patching no longer caused improvement.
But they were very calm and common sense type of parents so there wasn’t a whole lot of stress being communicated to the child. They prepared him well and made sure all of his questions got answered and he came through with flying colors.
I’m not saying surgery is what will necessarily happen to either of your grandkids but just letting you know what my previous experience with this has been.
With this child, the concern wasn’t really so much cosmetic (how he looked with the crossed eye) as it was functional and avoiding his developing reading/learning/eyesight problems in the future due to this.
But I also had a few kids in my classes over the years who had pretty mild cases of Amblyopia and it was just being treated with the specialized glasses and apparently that was all that was needed.
But I know that if I ever had a child with this problem, I’d definitely want evaluation and ongoing monitoring by an eye specialist rather than just a regular doc. I mean, I would be very grateful to the family doc for alerting us to the condition but would also be asking him for a referral to a specialist.
The vast majority of Amblyopia cases in kids tend to be of the milder variety but I would definitely want a very thorough evaluation by a specialist.
Just because it’s so common a problem in kids doesnt mean that the possibility of future problems it could cause should be taken lightly.
If a specialist told me it was pretty mild and not to worry overmuch, I’d be fine with that. But there’s no way that I would skip a thorough examination and testing by a specialist with the knowledge and experience to determine its possible severity. After all, ones eyesight is a critical issue for so many aspects of life. Better safe than sorry is my motto.
