Thanks for taking the time to reply, much appreciated. I didn't think it was the standard investigation for glaucoma, it's a worry. She's been poorly for a few months, obviously hasn't been able to see her GP as they're still limiting access. She's seemed to go down hill since July after what she thought was a bout of labyrinthitis which took 2 months to settle. She's very thin and frail, even though she's only 75. We shall just have to wait and see what, if anything, the MRI shows. Once again, many thanks for your replies.
