Area of Science:

  • Ophthalmology
  • Pediatrics
  • Developmental Neuroscience

Context:

  • Assessing visual development in early infancy is crucial for identifying potential developmental delays.
  • Existing methods may not be suitable for very young infants.
  • Standardized tools are needed for reliable infant visual function evaluation.

Purpose:

  • To introduce and evaluate a novel method for assessing visual functions in infants aged 1 to 3 months.
  • To adapt and utilize the Guide for the Assessment of Visual Ability in Infants (Gagliardo, 1997).
  • To establish age-appropriate visual milestones for early detection of functional alterations.

Summary:

  • A pilot study involving 33 infants (1-3 months old) assessed visual functions using a ring-and-string instrument.

  • Key observations included visual fixation (93.9%), eye contact (90.9%), and horizontal tracking (72.7%) in the first month.
  • By the third month, observations included inspecting own hands (42.4%) and increased arm movements (36.4%).

    • Impact:

    • This method facilitates the age-appropriate evaluation of infant visual functions.
    • Early identification of visual function alterations enables prompt referral to medical services for diagnosis and intervention.
    • Contributes to the early detection and management of visual impairments in infants.
