Cortico-retinal decoupling in anisometropic amblyopia: OCTA-VEP multimodal biomarkers reveal neurovascular mismatch patterns.
Article in BMC ophthalmology, 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
backgroundTo investigate the retinal microcirculation changes in children with anisometropic amblyopia through multimodal assessment and explore its correlation with neurophysiological dysfunction.
methodsThis prospective cross-sectional study recruited 68 treatment-naïve children (aged 4-14 years) with primary monocular anisometropic amblyopia. The fellow healthy eye served as the control. Macular microvascular parameters, including foveal avascular zone (FAZ) area and superficial capillary plexus (SCP) perfusion density, were quantified using optical coherence tomography angiography (OCTA). Pattern visual evoked potentials (P-VEP) assessed P100 latency and amplitude. Central macular thickness (CMT) and retinal nerve fiber layer (RNFL) thickness were measured. Correlations and multiple linear regression analyses were performed to identify predictors of best-corrected visual acuity (BCVA) in amblyopic eyes.
resultsCompared to fellow eyes, amblyopic eyes exhibited significant microcirculatory impairment: reduced SCP perfusion density (central: 0.27 vs. 0.29, P < 0.001; full: 0.44 vs. 0.46, P < 0.05), enlarged FAZ area (0.30 vs. 0.26 mm², P = 0.035), and increased CMT (141.00 vs. 131.50 μm, P < 0.05) and RNFL thickness (113.00 vs. 110.00 μm, P < 0.001). P-VEP revealed prolonged P100 latency (119.0 vs. 109.5 ms, P < 0.001) and decreased amplitude (12.8 vs. 19.25 µV, P < 0.001). SCP perfusion density correlated negatively with P100 latency (ρ=-0.341, P = 0.004), and SCP vessel density correlated negatively with CMT (ρ=-0.363, P = 0.002) and FAZ area (ρ=-0.424, P < 0.001). Multiple linear regression analysis (adjusted R²=0.625, P < 0.001) identified RNFL thickness (β = -0.546, P < 0.001) as a significant negative predictor of BCVA (logMAR), while SCP full perfusion density (β = 0.375, P < 0.001) and axial length (β = 0.237, P = 0.007) were significant positive predictors.
conclusionAnisometropic amblyopia is marked by a neurovascular mismatch, manifested through simultaneous retinal hypoperfusion, paradoxical thickening of structures, and delayed neural conduction. The combined OCTA-P-VEP assessment provides a comprehensive biomarker framework. RNFL thickness, SCP perfusion density, and axial length emerge as key independent predictors of visual acuity, suggesting complex interplays between structure, perfusion, and function.
