Dr. Gilmore led the journal club, and lab members discussed two different studies.

Poster

Synthesizing evidence about developmental patterns in human visual acuity as measured by Teller Acuity Cards

The poster presents a synthesis of published data on infant visual acuity measured with Teller Acuity Cards (TAC).

  • Goal: describe how acuity develops across the first years of life
  • Focus: comparing monocular vs. binocular testing
  • Approach:
  • Extracted values when available
  • Standardized and visualized results
  • Outcome: developmental trends across studies using TAC-I and TAC-II

Paper

Neijzen et al. (2025). Reference values for the Teller Acuity Cards II in infants and preverbal children: a meta-analysis

This article provides updated reference norms for TAC-II in infants and preverbal children.

  • Goal: establish age-related benchmarks for clinical use
  • Method:
    • Meta-analysis of published datasets (Wiley Link)
  • Correction factor applied to adjust TAC-I data to TAC-II scale (~0.3 octave)
  • Contribution: standardized values for clinicians and researchers assessing infant vision

Meeting Discussion Summary

During our lab meeting, we:

  • Clarified the goals of the poster (developmental synthesis) vs. the paper (reference norms).
  • Discussed strengths and limitations of the TAC method.
  • Compared findings and compatibility issues between TAC-I and TAC-II.
  • Reviewed basic statistical concepts relevant to meta-analysis and data harmonization.
  • Reflected on the broader implications: how measuring infant visual acuity informs early visual development research and clinical practice.
