Hi, I took my son to the optician where the diagnosed him with Esotropia. He is 9 and due to covid hadn't been to the opticians since 2019. He has been referred to an orthoptic consultant and told he will need glasses and to wear a patch to correct it. I have read though that 9 is quite late for a diagnosis, and correction treatment probably won't work. Also read that late onset is suspicious. Really just looking for reassurance. Thanks!
