Dd had been saying her eyes were going funny and she wanted to go to the optician because she thought she needed glasses like her friend. I must admit I wasn't too sure there was a genuine problem but when we saw the optician she confirmed DD is definitely experiencing intermittent double vision (diplopia I think it's called). She wants to see her again to use some dilating drops then she will refer her to the hospital for them to see which muscle/s are not working as they should. The optician seemed quite concerned. I had to go again today for my eyetest without dd and she asked after dd. I admitted I had done some googling after and started worrying about it being a Brain tumour. The optician didn't dismiss this as I had sort of expected but said that yes double vision can be a sign of something serious like a tumour but that it would be rare for there to be no other symptoms. I'm getting myself quite worried now. Does anyone know about this stuff or has a sense of whether I'm being over the top about it or not? Next appt is tues but then don't know how long before the hospital appt comes through.
