Insights

Visual acuity in children aged 1-4 years gradually improves, but adult levels are not reached by age 4. This study establishes age-specific norms for visual acuity in young children.

Area of Science:

  • Ophthalmology
  • Pediatric Medicine
  • Developmental Biology

Context:

  • Assessing visual acuity in young children (1-4 years) is crucial for early detection of vision impairments.
  • The Acuity Card method provides a standardized approach for this age group.
  • Establishing normative data is essential for tracking visual development.

Purpose:

  • To determine age-specific norms for visual acuity in children aged 1 to 4 years.
  • To evaluate the efficacy and reliability of the Acuity Card method for this population.
  • To document the developmental trajectory of visual acuity during early childhood.

Summary:

  • Visual acuity was assessed in 210 children (1-4 years) using the Acuity Card method.
  • Binocular visual acuity improved from 1.8 to 0.9 min arc, and monocular from 1.7 to 1 min arc.
  • Adult visual acuity levels were not achieved by age 4; age norms were established.

Impact:

  • Provides critical age norms for pediatric ophthalmologists and optometrists.
  • Demonstrates the Acuity Card method's high success rate and reliability in young children.
  • Facilitates early identification and intervention for visual development delays.
