We are looking for people who have reduced vision aged 18-70 years, in order to understand how the brain can generate hallucinations linked to eye disease.

Hallucinations are perceiving things or people that are not actually there. This research study hopes to understand the changes in the visual part of the brain that cause hallucinations to occur to help guide us in treating these.

We need people with reduced vision who experience visual hallucinations and also people with reduced vision who have never experienced visual hallucinations.

Participants would be asked to answer some questionnaires and undergo a non-invasive brain scan (MRI). Your participation would involve a single visit to the Wellcome Centre for Integrative Neuroimaging, FMRIB based at the John Radcliffe Hospital in Oxford.

We can only accept NHS registered UK residents. Travel expenses will be covered.
