Reduced plasma oxytocin levels in patients with open-angle glaucoma.
Article in Japanese journal of ophthalmology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
purposeWe explored the role of oxytocin in glaucoma by measuring the blood levels of oxytocin in glaucoma patients, comparing them to normal control subjects, and examining its association with clinical parameters. STUDY
designRetrospective cross-sectional study. MATERIAL AND
methodsAfter obtaining informed consent from 181 glaucoma patients and 44 age-matched control participants, we collected blood samples in ethylenediaminetetraacetic acid (EDTA) tubes and centrifuged them at 2000 g for 25 minutes at 4 °C. The resulting plasma was assayed for oxytocin concentration with an Enzyme Linked Immunosorbent Assay (ELISA) kit. We compared oxytocin concentrations in the control and glaucoma groups, and within the glaucoma group, we determined whether the oxytocin levels were correlated with mean deviation (MD) and sectoral total deviation (TD). Furthermore, in 33 patients who underwent at least five visual field tests over a two-year period following oxytocin measurements and received no surgical interventions during that time, we determined whether the oxytocin levels were correlated with MD slope and sectoral TD slopes.
resultsOxytocin levels in glaucoma patients were significantly lower than in age- and sex-matched normal controls (723.34 ± 303.44 vs. 557.59 ± 296.04 pg/ml, p=0.002). In glaucoma patients, oxytocin levels were significantly correlated with MD and inferior TD after adjustment for age and sex (β=0.149, p=0.041; β=0.156, p=0.034, respectively). There was a weak negative correlation between oxytocin concentration and MD slope (β=-0.334, p=0.084) and a weak negative correlation with central TD slope (β=-0.405, p=0.039), adjusted for age, sex, and history of additional eye drops.
conclusionOxytocin concentrations in glaucoma patients were significantly lower than in normal subjects and associated with the severity and progression of visual field defects. Given the wide variety of the pharmacological actions of oxytocin, it may be involved in the pathogenesis of glaucoma. Our results suggest that plasma oxytocin measurements may open a new avenue for glaucoma care.
