Has anyone any experience or advice please. Mum, who has AD, has complained of 'funny eyes' now and again over the last few months. She had her cataracts done a few years ago and can see better than me..... but she sometimes experiences days when she finds it difficult to focus and feels wobbly, we have taken her to the docs on several occasions and they can find nothing wrong, her medication has remained the same for a while, apart from them changing her warfarin dose over the last two weeks as her INR level was wrong, but the problem has occurred before this and she has been on warfarin for years without any problems. The doc and I put it down to her becoming anxious over various things but on the last couple of occasions she said she was not worried about anything. Does anyone have any ideas thanks.
