Telecentric model eye for correction of image distortion in adaptive optics ophthalmoscopes.
Article in Biomedical optics express, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Here, we demonstrate a telecentric model eye for measuring scanning, sampling, and optical distortion in AO ophthalmoscopes across a 10-diopter focus range, seeking to improve the reproducibility of adaptive optics (AO) ophthalmoscopy biomarkers. The model eye lens provides diffraction-limited performance when imaging with 800 nm light over circular 2.0, 3.0, 4.6, and 9.2° fields of view through 8, 6, 4, and 2 mm diameter aperture stops, respectively. Measurements of double-pass wavefront aberrations using both model and real retinas show that the use of opal glass model retinas, rough model retina surfaces, and wavefront sensing beacon scanning mitigate first-pass aberrations. This is particularly important, as first-pass aberrations are often assumed but not always achieved in AO ophthalmoscopes. Using the model eye with custom distortion estimation algorithms, we recorded 0.06% non-isotropic scaling repeatability, 0.02° shear repeatability, 0.5% reproducibility for both metrics and a root-mean-square residual distortion of 0.1 pixels across the field of view and focus range.
