About

This research aims to investigate Charles Bonnet Syndrome visions (CBS). CBS is the term used when a person has pseudohallucinations from some loss of sight. A CBS vision is different from a typical hallucination as the person has ‘insight’: they know what they are seeing is unreal.[1] Images range from simple colours and geometric shapes up to a wide variety of complex forms. The term visions is preferred by the CBS community due to the existing stigmas surrounding hallucinations.

It is important to note this is not medical research. The proposed research will focus on inquiry into how mental perceptions become physical through design. Of particular interest and explored in this study is the indispensable link between metaphor and image. Metaphors are thought connections essential for both day-to-day life and the night-time dreaming state.[2],[3]

An Interactive & Immersive Digital Experience

inclusive and immersive
meaningful, informative
understandable, playful, sharable, accessible

Creative Intention
Seeing through our eyes : Inside the CBS experience : Not a documentary, an emotional experience

Key thoughts
Through the applied use of creative technology, the objective is to make the condition relatable. In addition, communicate and explore the visions and the metaphorical connections through installations.

Creative Idea
Utilising media art and design so people can see and interact and immerse themselves within the CBS syndrome

Theme
Promoting awareness and creating validation: dissolving the stigma

Story
Personal experience with CBS keeps this topic close to my heart. There is an empathic link to challenges the CBS community face: primarily the stigmas and misdiagnoses. Co-creating with the CBS community is an essential part of the research. An interactive & immersive digital experience offers to reveal CBS visions and the lived experience people face day-to-day.  It will be an exhibition for all who are curious about vision-thought processes: for the CBS community, friends, family, and medical practitioners.

Studies into CBS are primarily conducted by the Ophthalmic, Neurological, and Psychiatric fields and approached with the primary concerns of these medical specialities. Alternatively, this research approaches from the creative field of design and is practice-based.

Conceptual functions are interesting in the context of visions as the gaps from vision loss are filled in by images that are seemingly abstract in place and time.

Jason Barton explains deafferentation as ‘the big picture’. Damaged areas can overlap regions that process different visual objects or effects.[1] These different areas fill in when visual information is missing. Sorting of information to fill in the missing and create sight is constructing normality: where the future is like the past. This can be explained by the Principle of the Uniformity of Nature put forward by David Hume, where everyday life corresponds to recurring similar situations and effects. The reassembly of the disassembled visual information is not understood.[2] Conscious visual perception does need the familiar to be able to identify context and environments. Maurice Merleau-Ponty in Phenomenology of Perception narrates:

the men I see from a window are hidden by their hats and coats, and their images cannot be imprinted on my retina. I therefore do not see them, I judge them to be there. Once vision is defined in the empiricist way as the possession of a quality impressed upon the body by a stimulus, the least illusion, endowing the object as it does with properties which it does not possess on my retina, is sufficient to establish that perception is a judgement.[3]

Metaphors are thought connections essential for both day-to-day life and the night-time dreaming state.[4],[5]  The wonder of metaphors is illustrating one thing as another, where the ambiguity of one concept causes imaginative links creating clarity for another. Utilising this ambiguity is creative through lateral connections of visual imagery.[6] Metaphor is indispensable for abstraction, non-literal explanations and linking complex ideas.[7]  My proposition is that image formation within complex visions link to metaphorical thoughts.

CBS Visions: realm of image crosses over into the realm of perception

visual creative experience 
simple to complex

Charles Bonnet Syndrome visions create a fascinating world where the realm of image crosses over into the realm of perception. CBS is the term used when a person has pseudohallucinations from some loss of sight. The term visions is preferred by the CBS community due to the existing stigmas associated to hallucinations, although this is somewhat controversial. A CBS vision is different from a typical hallucination as the person has ‘insight’: they know what they are seeing is unreal.[1] Accompanying sounds, psychiatric causes, and medications must be ruled out to diagnose CBS. While CBS is considered a rare diagnosis, it is experienced by 0.4-30% of all people with sight loss.[2]

In a 2015 interview, Dominic ffytche, a recognised leader in the brain mechanisms of vision and Charles Bonnet Syndrome (CBS), described CBS as follows:

Charles Bonnet Syndrome) can occur as a result of any eye problem… The hallucinations range from very simple dots, coloured blobs, sparkles of light … through to more formed images such as a brick wall, a geometrical pattern or a disembodied face … People may also see figures that are usually in some form of elaborate costume such as a Napoleonic uniform.3
