Transient Retinal Vessel Whitening After Whole-Ventricle Radiotherapy.
Article in Cureus, 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
We report a case of transient peripheral retinal vessel whitening following whole-ventricle radiotherapy in a pediatric patient, which resolved spontaneously without signs of ischemia. An 11-year-old girl with a pituitary germinoma underwent chemotherapy and whole-ventricle radiotherapy (23.4 Gy in 13 fractions). At two months post-treatment, ultra-widefield scanning laser ophthalmoscopy revealed bilateral peripheral retinal vessel whitening, raising suspicion of nonperfusion areas. However, optical coherence tomography angiography (OCTA) confirmed preserved retinal blood flow without ischemia. Visual field testing did not reveal any abnormalities. No intervention was performed, and the whitening resolved spontaneously within two months. Unlike typical radiation retinopathy, this represents a reversible, non-ischemic process, which could be attributed to the limited radiation exposure received during whole-ventricle radiotherapy and vascular plasticity in young patients. Given that radiation retinopathy is generally considered uncommon below 45 Gy, this case presents a characteristic retinal vascular change occurring at lower radiation doses and underscores the importance of retinal evaluation even in low-dose irradiation settings. Non-invasive imaging techniques, such as OCTA and ultra-widefield scanning laser ophthalmoscopy, can be valuable for monitoring subtle radiation-induced retinal changes. Further research is needed to refine screening and management strategies for radiation-induced retinal effects.
