My wife Jan can, I'm sure, no longer see. I believe her eyes could function, but that the dementia has destroyed the neural connections that feed images to her brain - which can no longer interpret them anyway. Also, physically there are problems and her left eye appears lazy. She can never focus on me [or anyone else] when I am [they are] anywhere near her. Very occasionally, for a few seconds only, her eyes will seem normal and she may suddenly appear to be able to see the person in front of her, then her eyes immediately drift off again. The eye people have accepted that there is no way to determine what or whether she can see, since she has also lost speech that is recognisable, or comprehension of what they are trying to do. The question is - has anyone else come upon this, and have they ever managed to register such a person as either partially sighted, or blind? Terms of the EPS I have for Jan say that I need to invest what little money she has to best effect. At the moment, she pays a little tax, mostly because of a small occupational pension. She would receive additional allowances if she were registered blind.
