Intraocular pressure and myopia progression in Chinese children: the Anyang Childhood Eye Study
Bibliographic record
Abstract
PURPOSE: To explore the relationship between intraocular pressure (IOP) at baseline and myopia progression in Chinese children from the Anyang Childhood Eye Study. DESIGN: Prospective school-based cohort study. METHODS: A total of 1558 grade 7 students completed the entire 2-year study. Ocular biometry, cycloplegic refractions and pneumotonometry were performed. Three years of follow-up have been completed for the children aged 12 years. The refractive groups and the tertiles of IOP were assessed by analysis of variance, to look for differences in mean values of spherical equivalent and IOP, respectively. RESULTS: The children's mean baseline IOP was 15.87±3.42 mm Hg. Mean IOP was significantly higher in girls by 0.57 mm Hg (p=0.024). In the whole sample, there was a mean change in spherical equivalent of -1.05 D over 2 years. The baseline IOP was 15.69 mm Hg in those progressing 1 D or more vs 16.09 mm Hg for those progressing <1 D (p=0.022). In the myopic group, myopes progressing >1 D had mean IOP of 15.94 vs 16.42 mm Hg for those myopes progressing 1 D or less (p=0.024). CONCLUSIONS: In this sample of Chinese children, myopia progression over 2 years was inversely related to IOP, suggesting that IOP had essentially no relationship with myopia progression in school children. The lower IOP in progressing myopic eyes may indicate more compliant sclerae.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
