Summary
Visual impairment affects 6.6% of children surviving acute nontraumatic coma, persisting at 12 months. This study determined the incidence and severity of vision loss in pediatric patients after coma.
Area of Science:
- Pediatric Neurology
- Ophthalmology
- Epidemiology
Background:
- Acute nontraumatic coma in children is a critical condition requiring comprehensive assessment.
- Understanding the long-term sequelae, particularly visual impairment, is crucial for patient management and rehabilitation.
Purpose of the Study:
- To ascertain the incidence and severity of visual impairment in pediatric patients following acute nontraumatic coma.
- To evaluate the persistence and progression of visual deficits over a 12-month period.
Main Methods:
- Prospective epidemiologic study conducted over 18 months in England.
- Inclusion criteria: children aged 1 month to 16 years with Glasgow Coma Score ≤12 for >6 hours or death within 6 hours of consciousness decrease.
- Ophthalmologic assessments at 6 weeks and 12 months for survivors.
Main Results:
- 287 children were studied; 127 died.
- Visual impairment was confirmed in 10 of 137 survivors at 6 weeks.
- At 12 months, 9 children had persistent visual impairment, and 1 showed improvement.
Conclusions:
- 6.6% of pediatric survivors of acute nontraumatic coma experienced persistent visual impairment at 12 months.
- The incidence of visual impairment in this population is estimated at 0.97 per 100,000 children annually.

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...
01:12Visual 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"...
01:28Traumatic Brain Injury l: Introduction
DefinitionTraumatic brain injury, or TBI, is a disturbance of normal brain function induced by an external mechanical force, such as a direct blow to the head or a penetrating injury. It can affect both brain structure and function, producing a wide range of clinical outcomes. TBI is a heterogeneous condition, meaning its effects may differ based on the type, location, and severity of the injury.Basis of ClassificationTBI is classified based on severity, injury mechanism, or pathophysiology.
