Eye examinations for dementia patients

Ruth Bennett MSc MCOptom, provides advice on eye examinations for Dementia patients.

The word dementia describes a set of symptoms that may include memory loss and difficulties with thinking, problem-solving or language. Dementia is caused when the brain is damaged by diseases, such as Alzheimer’s disease or a series of strokes. Dementia is progressive, which means the symptoms will gradually get worse.

It is really important for those with dementia to have an eye examination. Those with dementia may not report problems with their vision as we might expect.

At Lesley Cree Opticians we are well placed to examine patients with dementia. We have a relaxed atmosphere, friendly staff and long appointment times.

Q: I suspect someone diagnosed with dementia is beginning to lose their sight. How can I be sure?

A: The effects of dementia may disguise sight loss caused by an eye condition or normal ageing of the eye. Check if the person finds it difficult to do any of the following to help you confirm possible sight light loss:

  • Recognise people
  • Be in bright light, low light or both
  • Read facial expressions
  • Find things
  • Read, or enjoy familiar hobbies
  • Manage in unfamiliar surroundings
  • Locate food on the plate
  • Manage current spectacles (perhaps saying “I need new glasses.”)

If you suspect someone with dementia has sight loss then a full diagnosis is essential. A full eye examination, free to eligible people, is available at high street optometrists. We are used to adapting the test for the individual and can assess eyes even if someone cannot read the chart. People who can’t attend without support may be eligible for an eye examination in their home.

Diagnosis is important as some eye conditions that cause sight loss can be treated to avoid further loss of vision. Knowing what eye condition someone has may give you an idea of the kind of sight loss they have and how best to help them manage with the changes in their vision.
