Insights

Early visuospatial attention in preterm infants predicts later cognitive and motor development. An eye-tracking test can help identify infants at risk for neurodevelopmental issues, enabling timely interventions.

Area of Science:

  • Neuroscience
  • Developmental Pediatrics
  • Ophthalmology

Background:

  • Visuospatial processing is crucial for neurodevelopment.
  • Early assessment of visuospatial skills in preterm infants is important for predicting outcomes.

Purpose of the Study:

  • To examine the association between early visuospatial attention and processing and later neurodevelopmental outcomes in very preterm infants.
  • To evaluate the utility of an eye-tracking paradigm for early detection of neurodevelopmental risks.

Main Methods:

  • Assessed visuospatial attention and processing in 209 preterm infants (<30 weeks gestation) using eye-tracking at 1 and 2 years.
  • Calculated average reaction times to fixation (RTF) for attention (Cartoon stimuli) and processing (Motion and Form stimuli).
  • Examined associations between RTFs and cognitive, motor, language, and behavioral outcomes at 2 years using Bayley Scales (Bayley-III), Lexi test, and Child Behavior Checklist.

Main Results:

  • Slower RTFs at 1 year were linked to lower cognitive scores on the Bayley-III at 2 years.
  • Specifically, 100 ms slower Cartoon and Motion RTFs correlated with decreased cognitive scores.
  • A 100 ms slower Cartoon RTF was also associated with a decrease in motor Bayley-III scores.

Conclusions:

  • Early visuospatial attention and motion processing at 1 year predict cognitive and motor development at 2 years in preterm infants.
  • An eye-tracking test offers a nonverbal method for early identification of preterm infants at risk for adverse neurodevelopment.
  • Timely identification facilitates earlier interventions for improved developmental trajectories.
