Summary
A young boy experienced complex visual hallucinations after losing his sight. This rare phenomenon, typically seen in adults, has not been previously documented in young children with vision loss.
Area of Science:
- Neuro-ophthalmology
- Pediatric neurology
Background:
- Complex visual hallucinations are documented in adults with acquired vision loss.
- Causes can be ophthalmological or neurological.
- Hallucinations in children with vision loss are poorly understood.
Observation:
- A four-year-old boy developed complex visual hallucinations after becoming totally blind.
- This occurred one week after total vision loss, following six months of deteriorating vision.
- The vision loss was precipitated by surgery for a large optic nerve glioma.
Findings:
- The case presents complex visual hallucinations in a young child with recent total blindness.
- Hallucinations included moving figures, animals, and familiar objects.
- This represents a potential pediatric manifestation of Charles Bonnet syndrome.
Implications:
- This case expands the understanding of visual hallucinations in pediatric acquired vision loss.
- It suggests that young children may experience hallucinations similar to adults.
- Further research is needed to explore the prevalence and mechanisms of these hallucinations in children.

01:24Vision
Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.
01:22Photoreceptors and Visual Pathways
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...
01:24Color Vision
Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.
01:12Visual Agnosia
Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round end"...
01:24Prosopagnosia
Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...
01:26Positive Symptoms Schizophrenia: Hallucinations and Delusions
Schizophrenia is a complex psychiatric disorder characterized by a range of symptoms that significantly impact cognition, behavior, and emotional regulation. Among these, the positive symptoms stand out as they involve the addition or exaggeration of normal mental functions, deviating markedly from typical behavior and perception. Hallucinations and delusions are prominent positive symptoms, each profoundly affecting the individual's experience of reality.
