Summary

This study looks at how common Charles Bonnet Syndrome (CBS) is in people with vision loss from conditions like macular degeneration or glaucoma. CBS causes complex visual hallucinations without mental illness. Researchers will survey 640 participants to measure how often it happens and how it affects anxiety, mood, and quality of life. No treatment is given; the goal is to better understand and identify the condition.
