Layer-by-layer macular, peripapillary and choroidal thickness and minimum rim width in patients with clinically unilateral pseudoexfoliation syndrome: cross-sectional analysis using glaucoma module premium edition of the spectralis SD-OCT.
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
backgroundTo evaluate layer-by-layer retinal thickness, peripapillary retinal nerve fiber layer (pRNFL) measurement, minimum rim width (MRW), and subfoveal choroidal thickness (CT) in clinically unilateral pseudoexfoliation syndrome (PEXS), comparing affected, fellow and healthy eyes.
methodsThis research involved 65 eyes (PEXS and fellow eyes) of 65 unilateral PEXS patients and 80 eyes of 80 healthy controls. Heidelberg Spectralis optical coherence tomography (OCT) with Glaucoma Module Premium Edition (GMPE) software was used to assess layer-by-layer macular thickness [including macular nerve fiber layer (mNFL), ganglion cell layer (GCL), inner plexiform layer (IPL), inner nuclear layer (INL), outer plexiform layer (OPL), outer nuclear layer (ONL), retina pigment epithelium (RPE)], pRNFL and MRW. CT was measured using EDI-OCT.
resultsThe median age was 66.00 (62.00-73.00) years for PEXS group and 65.00 (60.00-69.75) years for healthy controls (p = 0.271). All of the 9 ETDRS macular regions of mNFL, GCL, IPL, INL, OPL, ONL, RPE thickness, pRNFL and BMO-MRW parameters were significantly lower in PEXS and fellow eyes than in control eyes (p < 0.05, for all). However, no significant differences were observed between PEXS and fellow eyes for most parameters. Subfoveal CT was lower in PEXS and fellow eyes than in control eyes (p < 0.001).
conclusionGMPE analysis demonstrated that PEXS and fellow eyes were related with lower layer-by-layer macular and pRNFL thickness, MRW and subfoveal CT compared to healthy eyes. Furthermore, fellow eyes showed a similar decreased thickness as PEXS eyes. Further research is warranted to clarify whether pseudoexfoliation independently increases risk for neural injury.
