Reconstruction of three-dimensional retinal shape from refractive topography data.
Article in Scientific reports, 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
A three-dimensional retinal shape was reconstructed by refractive topography (RT).
methodsThe personalized optical models of the human eye were reconstructed based on geometric parameters from clinical measurements. The expected refraction distribution on the fundus was calculated for each model. Subsequently, the refraction-position conversion function (RPF) was derived by fitting the data sets, which included the field of view (FOV), vitreous thickness (VT), and refraction. Additionally, the coordinates on the fundus of the human eye were calculated from RT data through the RPF. Ultimately, a three-dimensional retinal shape was reconstructed.
resultsThe expected refraction was calculated on 6 subjects. The results demonstrate that the expected refraction decreased as the VT increased. However, when the FOV was greater than 8°, the expected refraction increased with increasing FOV. A polynomial was applied to fit the 656 data points, resulting in the formation of the RPF. The fitting results demonstrated that the relationship tended to be similar in general for different human eyes, but there were individual differences. This reconstructed method provided good agreement between the reconstructed three-dimensional retina shape and the OCT measurements.
conclusionThe reconstructed three-dimensional retinal shape from RT data enables new imaging protocols that improve visualization of retinal shape.
