PMID 34179762WHAT IT FOUND
Five days of cloud-based eye training improved saccade speed and accuracy in people with poor baseline eye movements.
Participants also reported significantly fewer neurobehavioral symptoms like dizziness and cognitive fog, while the control group showed no change or slight worsening.
Key findings
01The intervention group showed a significant decrease in Q ratio (better saccade velocity) and significant decrease in targeting error (better accuracy), while the control group worsened on both metrics.
02Self-reported neurobehavioral symptoms (NSI total score and overall symptom rating) improved significantly in the intervention group but remained stable or worsened slightly in the control group.
03The training consisted of 5 minutes of exercises twice daily for 5 consecutive days, delivered via a cloud-based program.

What it does not show
The study did not include an eye-tracked reading test, so direct evidence of improved reading comprehension or speed is lacking. There were baseline differences between groups on some measures, which may have influenced the results. The control group worsened on eye metrics, which the authors attribute to variability, but the reason for this decline is unclear. No adjustments were made for multiple testing, which increases the risk of Type I errors. The study population was asymptomatic for concussion and other neurologic disorders, limiting generalizability to those specific clinical populations. Follow-up was immediate post-intervention; long-term retention of gains is unknown.
Declared interests
The authors declare no conflicts of interest. The study was conducted in accordance with the Declaration of Helsinki and approved by the Institutional Review Board of East Carolina University.
The easy way to misread this
Do not assume these eye movement improvements translate directly to better reading comprehension or academic performance, as no functional reading test was conducted. Additionally, the control group's unexpected worsening on eye metrics suggests that natural variability or practice effects may complicate the interpretation of change scores without a more robust active control.
