Charles Bonnet syndrome for Greater Independence in Everyday Life

Unlike hallucinations linked to other medical conditions, CBS-related visions involve sight alone. There is nothing to hear, smell, or feel. Even though the experience can feel unsettling or alarming at first, most people retain awareness that the images are not genuinely present.

The syndrome can affect anyone who has experienced vision loss from any eye condition, regardless of age. Because impaired vision is more prevalent in later life, the majority of individuals with CBS are older adults, yet there is no age limit on who might develop the condition.

With healthy vision, light enters the eye and is captured by the retina — the light-sensitive tissue lining the back of the eye. Signals then travel along the optic nerve to the visual cortex, the brain region responsible for processing what we see. This entire journey is called the visual pathway.

There is no single diagnostic test for Charles Bonnet syndrome. A physician will typically conduct a conversation and may order further examinations to exclude alternative explanations for the hallucinations. When no other underlying condition is identified and the person has recently experienced vision reduction, CBS becomes the most likely cause.

If you begin noticing objects, scenes, or figures that you know are not actually in front of you, reach out to your GP, ophthalmologist, or optometrist. Most of these professionals have encountered CBS and can offer guidance. Bringing this article or similar information can help frame the conversation productively.

CBS hallucinations typically fall into two broad categories. The first involves basic geometric patterns, repetitive shapes, or linear designs. The second encompasses detailed, elaborate images such as animals, buildings, landscapes, or human figures.

Some people experience primarily simple visual phenomena, while others encounter highly complex scenes. It is also possible to shift between the two types or to have both occurring simultaneously at different times.

Hallucinations associated with CBS rarely feature recognizable faces of people you know or depictions of past events from your personal history. While not every image is disturbing, initial episodes often provoke fear or anxiety, which tends to ease as familiarity grows.
