Comparison of binocular vision indices in Parkinson's disease patients
Article in International journal of ophthalmology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
aimTo evaluate the differences in near point of convergence (NPC), fusional vergence, saccadic eye movements, versional eye movements, and heterophoria between patients diagnosed with Parkinson's disease (PD) and healthy subjects.
methodsA cross-sectional comparative study was conducted, enrolling two cohorts: a PD group and a healthy control group. The PD group was recruited
resultsA total of 42 PD patients and 41 healthy controls were included in the final analysis. The two groups were well-matched in terms of sex distribution [29 males (69.0%) in the PD group
conclusionPD is associated with significant binocular vision function impairment, with receded NPC and reduced near fusional vergence reserves being the most prominent disorders. These findings highlight the potential value of binocular vision assessment as a non-invasive biomarker for the early detection and clinical monitoring of PD.
