Correlation between visual function and corneal backscatter by Scheimpflug imaging or anterior segment optical coherence tomography in Fuchs endothelial corneal dystrophy.
Article in Japanese journal of ophthalmology, 2025. 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
abtractPURPOSE: To evaluate the correlation between corneal backscatter and visual function in patients with Fuchs endothelial corneal dystrophy (FECD). STUDY
designProspective case series.
methodsThis study included 53 eyes from 38 patients with FECD. Corneal backscatter was quantified using light scattering (LS) via Scheimpflug imaging, and signal intensity (SI) via anterior segment optical coherence tomography. We measured corrected distance visual acuity (CDVA) using the Landolt-C and Early Treatment Diabetic Retinopathy Study (ETDRS) charts and contrast sensitivity function with sine wave grading chart by the area under the log contrast sensitivity function (AULCSF) and letter contrast sensitivity (LCS).
resultsSignificant correlations were observed between LS and SI, particularly in the posterior 60 μm of the central 0-2-mm cornea. LS in the central 6-mm cornea was significantly correlated with CDVA (Landolt-C and ETDRS) or contrast sensitivity (AULCSF and LCS) in most layers or diameters. In the central 0-2-mm cornea, LCS and posterior LS had the strongest correlation (ρ = -0.58, P < 0.01), followed by AULCSF and posterior LS (ρ = -0.55, P < 0.01). In the central 0.5-2-mm cornea, anterior or posterior SI demonstrated significant correlations with CDVA (Landolt-C and ETDRS) and contrast sensitivity (AULCSF and LCS). AULCSF and posterior SI had the strongest correlation (ρ = -0.58, P < 0.01), followed by LCS and posterior SI (ρ = -0.56, P < 0.01).
conclusionThe corneal backscatter of the anterior and posterior central cornea of FECD is significantly correlated with visual function across both imaging modalities.
