Retinal microvascular changes in pediatric patients with thromboembolism: an optical coherence tomography angiography study.
Article in Irish journal of medical science, 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
backgroundMicrovascular changes in the retina can be detected in children with thromboembolism. These changes in the retina can be measured with optical coherence tomography angiography (OCTA).
aimThis study aims to evaluate retinal microvascular changes in pediatric patients who have experienced central nervous system thromboembolic events using OCTA.
methodsThis cross-sectional study included 36 children aged 7-16 years. Comprehensive ophthalmic evaluations, including OCTA imaging using the AngioVue system, were performed. Retinal vascular density (VD), retinal thickness, and foveal avascular zone (FAZ) parameters were evaluated in predefined macular regions. Radial peripapillary capillary vessel density (RPCVD) and retinal nerve fiber layer (RNFL) thickness were also measured.
resultsCompared to the control group, patients with thromboembolism exhibited a significant reduction in vascular density across all sectors of the deep capillary plexus (p < 0.05). Additionally, a significant decrease in vascular density was noted in the nasal sector of the superficial capillary plexus (p < 0.05). No significant difference was observed in the FAZ area between the groups (p > 0.05). RNFL thickness was significantly lower in all sectors in the patient group (p < 0.05). In contrast, peripapillary RPCVD was significantly higher in the patient group compared to the control group (p < 0.05).
conclusionOCTA enables the noninvasive detection of retinal microvascular alterations in pediatric patients with thromboembolism. These findings highlight the early vascular involvement associated with the disease and may serve as a valuable tool for clinical monitoring and follow-up.
