Lower Retinal Arteriolar Density Is Associated With Higher Cerebral Small Vessel Disease Burden: An Optical Coherence Tomography Angiography Study.
Article in Brain and behavior, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled it.
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
introductionIt is suggested that cerebral small vessel disease (SVD) plays a role in strokes and dementia. Retinal microvasculature imaged by optical coherence tomography angiography (OCTA) is suggested to be associated with cerebral microvessels. We measured the density of the retinal arterioles and venules on the superficial vascular complex (SVC) of OCTA images and investigated associations with SVD markers in older adults.
methodsParticipants underwent cerebral magnetic resonance imaging and OCTA imaging. An external algorithm (OCTA-Net) was used to segment the retinal vessels into arterioles and venules. SVD indicators [lacunes, white matter hyperintensity (WMH), perivascular spaces (PVS) and cerebral microbleeds (CMBs)] were determined according to the STandards for ReportIng Vascular changes on nEuroimaging (STRIVE)
results246 older adults (mean age = 58.84 ± 7.00 years; 38.21 % males) were included in our data analysis. After adjusting for covariates, lower retinal arteriole densities correlated with higher periventricular WMH (p = 0.025) and PVS in the basal ganglia (p = 0.027). Lower retinal venule density correlated with higher deep WMH burden (p = 0.014). Lower arteriolar density was associated with increased SVD burden (p = 0.035). Arteriolar complex branching was associated with periventricular WMH (p = 0.020) while venular complex branching was associated with deep WMH (p = 0.041).
conclusionRetinal vascular changes may reflect cerebral vascular changes as evidenced by OCTA-derived metrics.
