Effects of orthokeratology lenses on choroidal thickness and choriocapillaris perfusion in myopic children.
Article in Frontiers in medicine, 2025. 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
Purpose: To investigate changes in subfoveal choroidal thickness (SFChT) and choriocapillaris (CC) perfusion in children wearing orthokeratology (Ortho-K) lenses. Methods: This retrospective study included 61 myopic children, who were divided into two groups. The Ortho-K group wore Ortho-K lenses, while the control group wore single-vision distance spectacles. The SFChT, CC area and ocular parameters were measured before and after 1 week, 1 month, 3 months, and 6 months of treatment. Results: In the Ortho-K group, the SFChT significantly increased by 18.23 ± 11.35 μm. The CC area significantly increased by 0.39 ± 0.11 mm Conclusion: Orthokeratology notably increases SFChT and improves CC perfusion. Changes in choroidal thickness are linked to alterations in choriocapillaris perfusion. These effects are associated with the effect of orthokeratology in slowing axial length elongation.
