My wife is diabetic, controlled by diet which was coincidentally first identified not that long after she was diagnosed with dementia.
Her eyesight has always remained pretty good, only needing reading classes (which she hardly ever used). She started having the diabetic eye screening tests each year, but this became more and more difficult as the dementia progresses.
The tests are done in a mobile unit that comes to the surgery but as the limited space inside prevented me from accompanying my wife, they changed her appointments to their unit at the local hospital.
The last time my wife went was around 2 years ago where despite our best efforts, we couldn't get her to hold still enough or follow the instructions to look at the green dot, etc. They said that there was little they could do and we agreed to remove her from the annual test programme.
Similarly, I have not taken her for normal eye tests for quite a few years and she also cannot cope with the breast screening appointments (despite going in with her sister - they couldn't get her to hold still or get into the right position).
Similar outcome for her annual diabetic nurse annual checks - blood pressure check not helped by her moving her arm about; couldn't get her to step on the scales; reflex prick test on her feet was hilarious
.
So rightly or wrongly, I focus (pardon the pun
) on the daily trials and tribulations of dealing with her dementia.
