My mother has dementia and has been complaining about her eyesight getting worse. I had taken her to see an ophthalmologist and after performing several test he recommended that I take her to see a retinal specialist. I took her to the specialist and several test were done to her eyes, but couldn’t find anything wrong. I returned to the eye doc for an eye test and glasses. After getting the glasses she had again complained that she could not see well with them. Again I went to the eye doc and again an eye test was done, but this time my mom said that she could not see the largest letter clear. The eye doc was dumb found and did not know what else to do for her since all the usual test had been good. I am wondering if her dementia is affecting her vision portion of her brain. Has anyone had this happened, and could I be correct? Could anything be done for her?
Take her for a walk, see if she can read street signs, house numbers. Take her to McD and see if she can read the menu items. Then you can see if it is just confusion or if she really can't see.
I'd next see the neurologist who treats her dementia.
If it's vascular dementia you're dealing with, it can affect any part of the brain so yes it could affect the eyesight. But so could lots of other things so it is worth investigating.
