My 9 month old ds has odd-sized eyeballs - the left one is noticeably larger than the right. My GP says its quite common but has referred us to a consultant to make sure all is OK. It was only after I left the surgery that I realised I hadn't asked what was causing it, if it's so common. As I've no doubt got a lengthy wait before the hospital appointment comes through, has anyone else got any experience or advice about this?
