Sequential multimodal imaging of varicella-zoster virus-associated acute retinal necrosis: Insights supporting a neurotropic hypothesis.
Article in European journal of 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
PurposeTo characterise the sequential macular changes using spectral-domain optical coherence tomography (SD-OCT) in acute retinal necrosis (ARN) and compare these with the von Szily model of neuronally transmitted herpetic retinitis.MethodsSingle-patient case study with serial SD-OCT imaging and analysis of aqueous humour varicella zoster virus (VZV) levels.ResultsA 30-year-old immunocompetent woman presented with 360° confluent peripheral retinal necrosis and scattered multifocal lesions in the right eye. VZV DNA was detected in the aqueous humour by polymerase chain reaction (PCR). At baseline, multiple radial retinal folds around the fovea were visible, appearing as sharp inner retinal undulations on SD-OCT. Numerous continuous and beaded vertical hyperreflective strips (VHRS) were present within the outer nuclear layer; in the parafovea, these followed the oblique course of the Henle fibre layer. By days 4-5, neurosensory detachments developed beneath VHRS, with subfoveal choroidal thickness peaking at day 9. Despite systemic and intravitreal antivirals, the right eye deteriorated to light perception, hypotony, and phthisis.ConclusionSequential macular SD-OCT in VZV-associated ARN revealed inner retinal undulations and vertical hyperreflective strips in the outer nuclear layer preceding neurosensory detachments. These observations may correspond to viral dissemination along neuronal pathways from the inner to outer retina, consistent with mechanisms described in animal models. Recognition of these imaging biomarkers could support early detection of macular involvement and improve understanding of ARN pathogenesis in humans.
