We regularly do home eye tests on patients with dementia.
Dementia is not a disease but a term used to describe symptoms including memory loss and difficulties with thinking. These are the most well known symptoms of Alzheimer’s disease which is the most commonest cause of dementia but not the only disease.
The symptoms of dementia will vary according to the part of the brain that is affected and the exact disease that is causing dementia. Other symptoms can include disruption of speech, mood and personality.
Did you know that one of the other lesser known symptom of dementia is it affects your vision.
Dementia can affect vision because both brain and the eyes contain nerves and dementia affects the nerves also.
Common causes of sight loss with dementia are:
- Eye conditions e.g cataract, macular degeneration and glaucoma.
- Health conditions e.g stroke and diabetes.
- Normal ageing of the eye.
- Dementia itself namely Alzheimer’s disease, Parkinson’s disease and Posterior Cortical Atrophy (PCA).
Patients with dementia can have difficulty in vision due to the brain being affected but still have healthy eyes, patients with dementia suffer from perceiving what they see rather than how sharp the vision.
5 common visual defects that are identified with Alzheimer’s Disease :
- Reduced ability to detect motion.
- Decrease sensitivity to contrast in colour gradients and objects within their background.
- Problems with depth perception such as judging distances.
- Difficulty in detecting colours such as blue and purple.
- Reduced peripheral vision (Reduced vision around the edges and sides of your sight when staring forward).
If you are a carer for someone with dementia do look out for the following signs :
- Difficulty with reading and writing.
- Problems with recognition of people.
- Coping with varied bright and low light intensity.
- Forgetful of objects and locations.
- Bumping into obstacles.
- Difficulty in reaching for things such as door handles.
- Problems with their vision even with their glasses on.
