Ophthalmology Research Group
As our brains and eyes age, our vision can be affected. Sometimes this happens because of problems in our eyes like cataract, glaucoma or age-related macular degeneration. And, sometimes this happens because of problems in our brains like a stroke or from dementia. Often, there will be a complex interaction between what is going on in our brains and what is going on in our eyes. It’s important to understand more about the way in which the ageing eyes and brain affect vision and influence one another so that we can offer appropriate care to older people who are having visual difficulties. Our research group includes ophthalmologists, psychiatrists, psychologists and neurologists in order to develop a multi-faceted approach to research into ageing vision.
Current research includes: investigating the impact of early dementia on cataract surgery outcomes; factors influencing decision making for eye treatment in those with advanced dementia; the influence of Parkinson’s disease on the visual system; the causes of double vision in Parkinson’s disease; the occurrence of visual hallucinations in eye disease; the relationship of eye diseases with dementia in the elderly population; measuring cognitive scores in those with blindness and visual impairment.
Our vision is:
- To develop a multi-disciplinary approach to vision research
- To understand more fully how the ageing brain influences vision
- To transfer this understanding into changes which will improve the care of elderly patients with troublesome visual symptoms.
