    Visual evoked potentials (VEPs) can predict poor outcomes in high-risk infants. Abnormal VEPs, particularly absence or abnormal waveforms, are key indicators for prognosis, suggesting selective, early, and repeated VEP testing.

    Area of Science:

    • Neuroscience
    • Developmental Pediatrics
    • Ophthalmology

    Background:

    • High-risk infants require early neurodevelopmental assessment.
    • Visual evoked potentials (VEPs) assess visual pathway integrity.
    • Predicting long-term outcomes in infants is crucial for timely intervention.

    Purpose of the Study:

    • To evaluate the predictive value of flash visual evoked potentials (VEPs) for clinical outcomes in high-risk infants.
    • To determine if VEP maturation correlates with neurodevelopmental outcomes at one year of age.

    Main Methods:

    • Flash VEPs were recorded in 109 high-risk infants.
    • VEP results were compared with clinical outcomes at one year of age.
    • VEPs were recorded early (within three months) and sometimes repeated for abnormal cases.

    Main Results:

    • 80% of infants had normal outcomes and normal VEP maturation.
    • 18% of infants exhibited abnormal VEPs.
    • Abnormal VEPs were significantly more frequent in infants with abnormal outcomes (54%) and poor outcomes (86%) compared to normal outcomes (14%).

    Conclusions:

    • VEPs are effective in predicting poor neurodevelopmental outcomes in high-risk infants.
    • Absence or abnormal waveforms in VEPs are significant prognostic indicators.
    • Selective, early (post-birth), and repeat VEP testing (around two months) is recommended, potentially guided by ultrasound findings.
