Fixation and saccadic performance throughout childhood in children born preterm: A multicenter eye-tracking study.
Article in Pediatric research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundChildren born preterm may experience alterations in the maturation of visual and oculomotor systems, but the long-term consequences on eye movement control throughout children's development are not well established. Our study examined how early birth influences fixation and saccadic performance during childhood.
methodsWe assessed a cross-sectional, multicenter cohort of 1506 children (502 preterm, 1004 full-term) aged 6 months to 12 years using the DIVE system, which provides precise measures of fixation stability, fixation duration, saccadic reaction time, and accuracy. We used logistic regression models to estimate the association between preterm birth and oculomotor control deficits, adjusting for gestational age and visual pathologies.
resultsPreterm children showed significantly more unstable fixations and slower saccadic reaction times than full-term peers across all age groups. Oculomotor deficits were more prevalent in preterm children (36.5% vs. 23.3%), with higher odds of impairment (OR = 1.89, 95% CI 1.49-2.39, p < 0.001). These differences emerged in infancy and persisted through middle childhood despite age-related improvements in both groups.
conclusionThese findings suggest that preterm birth may have lasting consequences for oculomotor control, underscoring the importance of early detection and targeted interventions to support visual and neurological development in preterm children. IMPACT: Children born preterm show persistent deficits in fixation stability and saccadic reaction time from infancy through middle childhood. These differences persist even after adjusting for visual pathology, gestational age, and sex. Eye-tracking provides a sensitive, reproducible approach to detect oculomotor dysfunction in pediatric populations. This study offers the largest age-matched assessment of oculomotor control across development in preterm and full-term children using a single standardized system. Integrating such assessments into routine pediatric care may enhance early intervention strategies and improve developmental outcomes for children born preterm.
