Characterization of the microbial profile in tears of patients with primary open-angle glaucoma: results from a pilot study.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
This pilot study characterized the tear microbiota profile in patients with primary open-angle glaucoma (POAG) and compared it with healthy controls. Tear samples from 22 participants (10 POAG patients and 12 matched controls) were analyzed using 16 S rRNA gene sequencing. While no significant differences were found in alpha diversity, beta diversity analyses revealed distinct microbial community structures between groups, with POAG patients exhibiting a more homogeneous and less diverse microbiota. Three phyla-Fusobacteriota, Planctomycetota, and Synergistota-were significantly more abundant in the glaucoma group (p < 0.0001), and 23 bacterial genera showed differential abundance. Additionally, preserved eye drops appeared to modulate microbial composition, with specific alterations observed in several genera. These findings support the hypothesis of ocular dysbiosis associated with POAG, potentially linked to inflammatory and immunological mechanisms. The study suggests that microbiota-based interventions, such as probiotics or postbiotics, may offer complementary therapeutic strategies, and highlights the need for longitudinal studies with larger sample sizes to validate these preliminary results.
