The incidence rates and prevalence of treated glaucoma in the United Kingdom, 2000-2022.
Article in PloS one, 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
purposeQuantify the incidence rates and prevalence of treated glaucoma in the United Kingdom (UK).
methodsUsing data from the Clinical Practice Research Datalink (CPRD) GOLD, we calculated crude and age-standardised incidence rates and prevalence of treated glaucoma in adult patients from 2000 to 2022, stratifying by age, sex, year of diagnosis, and region.
resultsWe identified 112,632 cases of glaucoma in 82.7 million person-years (py) from 2000 to 2022. The age-standardised incidence rates of glaucoma remained stable from 2000 to 2019 (128.77, 95% CI 125.15-132.40 to 112.63, 95% CI 108.75-116.52 per 100,000 py) with a marked reduction in 2020 (69.50, 95% CI 66.31-72.68 per 100,000 py) and a slight increase in 2021 and 2022 (94.09, 95% CI 90.23-97.96 to 91.70, 95% CI 87.61-95.79 per 100,000 py). Incidence rates sharply increased with age, peaking at 579.70 (95% CI 572.27-587.13 per 100,000 py) in the 80-89 age group, with more males in all age groups. The incidence rates of glaucoma were highest in England, London and Wales (3-8% above average), and lower in Northern Ireland and Scotland (11-16% below average). The prevalence of glaucoma increased by 24.7% from 1.18% (95% CI 0.89-1.47%) to 1.47% (95% CI 1.03-1.90%). It was highest in the elderly >90 years (11.5%).
conclusionsIn our large nationwide study in the UK, the incidence rates of glaucoma in the UK remained fairly stable from 2000 to 2019, with a significant decrease observed in 2020 due to the COVID-19 pandemic. Meanwhile, the prevalence of glaucoma has increased, reflecting the aging population. Both the incidence rates and prevalence varied widely across age groups, sexes, and different regions of the UK. Considering the aging UK population and the increasing prevalence of glaucoma, this eye condition represents a growing burden on the National Health Service in the UK.
