Comparison of anterior segment parameters in primary angle closure suspects and pseudoexfoliation syndrome with occludable angles.
Article in International ophthalmology, 2025. 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 compare anterior segment parameters between primary angle-closure suspects (PACS) and eyes with pseudoexfoliation syndrome (PXS), and those with an occludable angle.
methodsThirty-three eyes of 21 subjects were enrolled in the PACS group, and 34 eyes of 28 subjects were enrolled in the PXS group. All eyes underwent anterior segment optical coherence tomography with CASIA2. Multiple quantitative measures, including anterior chamber depth (ACD), anterior chamber width (ACW), lens thickness (LT), lens vault (LV), angle opening distance (AOD), angle recess area (ARA), trabecular iris surface area (TISA), and iris thickness (IT), were compared between the groups using generalized estimating equations.
resultsThe mean age was higher in the PXS group (58.2 ± 8.2 vs. 69.3 ± 9.1; p < 0.001). There were more females in the PACS group (63.6% vs. 29.4%; p = 0.005). After adjusting for age, sex, and axial length, the PXS group had lower lens thickness (4.625 ± 0.824 vs. 4.967 ± 0.35; p = 0.018) and higher ACD (2.271 ± 0.567 vs. 2.086 ± 0.281; p = 0.04), while there was no significant difference in the LV (0.929 ± 0.292 vs. 1.027 ± 0.231; p = 0.344). There were no significant differences in AOD500, AOD750, ARA500, ARA750, TISA500, TISA750, or IT750 between groups.
conclusionThe thickness of the crystalline lens may play a determinant role in higher rates of peripheral anterior synechia (PAS) and angle-closure glaucoma in eyes with PACS, as well as lower rates of angle-closure glaucoma and PAS in eyes with PXS and occludable angles.
