Automated segmentation and quantification of peripapillary hyperreflective ovoid mass-like structures using swept-source optical coherence tomography.
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
backgroundPeripapillary hyperreflective ovoid mass-like structures (PHOMS) are emerging optical coherence tomography (OCT) markers for axoplasmic stasis. Accurate volumetric quantification is critical for monitoring their progression but remains challenging due to the complex 3D geometry of these structures.
methodsWe developed a dual-branch deep convolutional neural network to automatically segment and quantify PHOMS volumes using swept-source OCT data from 70 adolescent eyes. The architecture integrates a segmentation branch and a classification branch to resolve boundary ambiguities. Performance was validated against manual ground truth from expert graders.
resultsOur automated segmentation achieved a human-equivalent accuracy level in identifying PHOMS, achieving a mean Dice coefficient of 0.810 and an intraclass correlation coefficient of 0.990 in comparison with expert graders’ assessments. Volumetric measurements demonstrated a robust correlation (r = 0.992) between the automated and manual methods.
conclusionsThe proposed deep learning framework enables rapid, reliable, and automated 3D quantification of PHOMS in adolescents. This tool holds significant potential for large-scale clinical screening and the longitudinal monitoring of PHOMS.
