Most people know that people with Parkinson’s suffer from problems with movement. But symptoms affecting vision can be just as disabling and distressing.
For some people with Parkinson’s visual symptoms take the form of hallucinations involving people or animals. For others it can be difficulties with everyday tasks such as reading the newspaper or following maps. These problems are not well studied in Parkinson’s and there is a real need to understand these symptoms better.
Our study will measure changes in vision in a large number of people with Parkinson’s and healthy volunteers, via the internet. You can take part in our study using your own computer at home. You will see six different optical illusions. We have designed each illusion to challenge a different vision process in the brain to find out which parts of vision are most affected. We will compare how different people perform in each illusion to test which aspects of vision are affected in each person.
Our aim is to work out what sometimes goes wrong with vision in people with Parkinson’s. Our eventual goal is to design treatments to improve and help peoples’ vision.
It only takes a minute to sign up, and you can take part in the study whether you have Parkinson’s or not.
The first part of the study consists of some questions about your health to help us analyse your results.
Once we know a bit about you and your health there are a series of simple vision tests.
The more people who take part, the more effective our research can be.

Dr Rimona WeilI am a neurologist specialising in Parkinson’s at University College London Hospital and the Royal Free Hospital in London. I am also a neuroscientist, based at University College London. I aim to understand how thinking and memory is affected in some participants with Parkinson’s. I use computer-based visual tasks and brain scans to investigate this question.
