Objective test findings in patients with chronic eye symptoms seeking care at an outpatient neck center: ligamentous cervical instability etiology?
Article in Frontiers in neurology, 2025. 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
Purpose: To examine the incidence and potential associations between eye symptoms and objective test findings in patients reporting to an outpatient neck center without known preexisting conditions. Methods: Consecutive patients between January 1 and June 30, 2022, reporting at least 1 of 6 eye symptoms (light sensitivity, blurry vision, eye pain/pressure, vision changes, seeing flashes of light, eye tearing) without known etiology underwent these tests: pupillometry, tonometry, ultrasound of carotid sheath and optic nerve sheath, and digital motion x-ray (videofluoroscopy) and upright cone beam computed tomography scan of cervical spine. Results: The analysis included 203/234 consecutive patients. Elevated optic nerve sheath diameter (total >12.2 mm) was documented in 98% (199/203). Supine cervical ultrasound revealed 99.5% (202/203) with internal jugular vein narrowing at C1: total internal jugular vein cross-sectional area <180 mm Discussion: Elevated optic nerve sheath diameter, elevated intraocular pressure, ocular dysautonomia, and succeeding eye symptoms may be pathophysiological effects of internal jugular vein compression and vagus nerve degeneration with underlying ligamentous cervical instability etiology.
