    Study Notes

    Pediatric Vision Care

    • First eye exam recommended at 6-12 months of age.
    • InfantSEE program provides free eye exams for 6-12 month olds.
    • Likelihood of having had an eye exam:
      • <6 years old: ~14%
      • 6-16 years old: ~31%
    • Undiagnosed vision problems are common, affecting:
      • 1 in 5 preschool children
      • 1 in 4 school-age children
      • Significantly higher in special populations (e.g., ADHD, autism, Down syndrome)
    • Vision problems interfere with classroom learning (80% mediated through vision).
    • Early intervention is crucial for better outcomes.
    • Vision screenings often miss ~95% of vision problems that affect learning.

    Likelihood of Eye Exams

    • Relatively low rates of eye exams in the pediatric population.
    • Parents/kids may not recognize/understand the need.

    Vision Problems and Learning

    • Visual conditions are prevalent among juvenile delinquents.
    • High rates of undiagnosed vision problems in students with IEPs.

    Vision Disorders

    • Fourth most common disability in the US.
    • Most prevalent handicapping condition in childhood.
    • Underlying vision problems affect 25% of schoolchildren.
    • Strabismus is a potential outcome in 4% of children.

    Cognitive Development

    • Jean Piaget's theory describes cognitive development in distinct stages.
    • Sensorimotor (birth–2 years): learning through physical actions.
    • Preoperational (2–7 years): symbolic representation, difficulty understanding different viewpoints.
    • Concrete Operational (7–11 years): limited logical thought processes, concrete examples needed.
    • Formal Operational (12+ years): logical reasoning, abstract thought.

    Visual Development

    • Key stages of visual acuity development.
    • Detection (minimum visible) and resolution (minimum separable) of visual stimuli.
    • Vernier (hyperacuity) and recognition of visual stimuli.
    • Binocularity.
    • Optical pathway integrity, visual processing, visual efficacy, and sensory integration are critical components of visual development.

    Visual Acuity

    • Important measurement for every examination (refractive, pathological, or attentional).
    • Different measurement types exist. (Detection, Resolution, Recognition).

    Oculomotor Mechanisms

    • Crucial for eye movements to focus on and track moving objects (saccades).
    • Horizontal saccades develop before vertical saccades.
    • Pursuits follow movement, and convergence/divergence involves eyes moving together
    • Vestibulocochlear Reflex (VOR), which helps maintain gaze while the head moves.

    Primitive, Reflexes and Development

    • Primitive reflexes, such as the Moro, rooting, and plantar reflexes, are important for newborn development.
    • These reflexes integrate (go away) between 6 months to 2.5yrs.
    • Postural reflexes assist with posture, movement, and head control
    • The spinal Galant reflex and others help with this, also integrating within 6 months to 2.5 yrs.

    Symptoms of Unintegrated reflexes

    • Problems with balance, coordination, spatial reasoning and visual/physical difficulties can arise from prolonged unintegrated primitive reflexes.
