My 18 month old has been crossing her left eye for a few weeks. It rolls in towards the center. It started out being just when she was tired but now she is doing it quite a bit. Her nursery career today told me that her balance seemed off but I haven't noticed that, and as she is 18 months she takes tumbles all of the time anyway. Her sight is fine as far as i can tell but she does rub her eyes a bit. Our GP has referred us to a paediatric opthamalogist but we can't get an appointment for a month, and I'm concerned as it seems to be getting worse. Does anyone have experience with this? What kind of treatment did you have and was it effective?
