Reference values for the Teller Acuity Cards II (TAC II) in infants and preverbal children, a meta-analysis.
Synthesis in Acta ophthalmologica, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThe Teller Acuity Card (TAC) procedure is a preferential-looking method to assess visual acuity in infants and preverbal children and provides a quantitative measure of grating acuity. Several studies containing reference values have been published, the majority based on an older version of the TAC card set. In 2003, a new version of the TAC was released, called the TAC II. This study aims to provide clinicians with a unified set of age norms for the TAC II.
methodsWe conducted a literature search and extracted individual data points per age from either tables or figures. We performed a weighted regression on both the standard deviation and the mean visual acuity as a function of age. Furthermore, based on literature, we corrected data points from studies using the original TAC by subtracting 0.3 octave to align them with the TAC II age norms.
resultsA total of 5 studies, published between 1990 and 2006, provided binocular visual acuity data for 837 children and monocular visual acuity data for 1052 children. Age norms were derived from these combined data sets.
conclusionsThe TAC charts are the gold standard for assessing visual acuity between the ages of 0 and 36 months. We provide a unified set of age norms for TAC II, the most recent version of the TAC charts.
