Children can experience rapid visual recovery after severe hypoxic brain injury. Advanced MRI scans can help predict this recovery, offering hope for improved outcomes.
Area of Science:
- Neuroscience
- Ophthalmology
- Pediatric Neurology
Background:
- Cortical visual loss can occur after severe hypoxic brain injury.
- Understanding the mechanisms of visual recovery is crucial for pediatric patients.
Observation:
- A 12-year-old boy experienced cortical blindness following a severe snowboarding crash.
- Magnetic resonance imaging (MRI) revealed extensive hypoxic brain injury in visual pathways.
- Initial MRI findings suggested potential for recovery due to mixed edema types.
Findings:
- The patient demonstrated accelerated visual recovery, regaining 20/20 visual acuity and 40 sec/arc stereoacuity within weeks.
- Visual field examinations showed progressive expansion of the spared visual field over one year.
Implications:
- Protracted hypoxic cortical visual loss in children can lead to significant, rapid visual recovery.
- MRI is a valuable tool for assessing prognosis in pediatric hypoxic brain injury.
- This case highlights the potential for neuroplasticity and functional recovery in pediatric visual pathways.

Motion-induced Blindness
One thing becomes very salient after basic exposure to the science of visual perception and sensation: what people see is a creation of the brain. As a result people may fail to see things, see things that are not there, or see things in a distorted way.
To distinguish between physical reality and what people perceive, scientists use the term awareness to refer to what people perceive. To study awareness, vision scientists...

Inattentional Blindness
We generally think that we see things pretty well if they are close by and right in front of us. But do we? We know that visual attention is a property of the human brain that controls what parts of the visual world we process, and how effectively. Limited attention means that we can't process everything at once, it turns out, even things that might be right in front of us.
In the 1960s, the renowned cognitive psychologist...
