Evaluation of the segmented inner retinal layers in exfoliation glaucoma.
Article in International ophthalmology, 2023. 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 investigate the macular spectral domain optical coherence tomography (SD-OCT) measurements of the segmented inner retinal layers in patients with exfoliation syndrome (XFS), exfoliation glaucoma (XFG).
methodsThis prospective cross-sectional study included 28 eyes with XFS, 47 eyes with XFG, and 29 healthy controls. Thickness of the inner retinal layers, including retinal nerve fiber layer (RNFL), ganglion cell layer (GCL), and inner plexiform layer (IPL) was obtained from the horizontal SD-OCT scans. Functional correlation of structural parameters was analyzed using the mean sensitivity (MS) values on 10-2 visual fields.
resultsThe RNFL, GCL, and IPL were thinnest in eyes with XFG. Among these retinal layers, IPL was significantly thinner in eyes with XFS than healthy controls (p = 0.02) and the IPL thickness was significantly correlated with the corresponding MS scores on 10-2 visual fields (r = 0.492, p = 0.02) in eyes with XFS. Neither GCL nor RNFL thickness values demonstrated significant correlations with functional parameters in eyes with XFS (r = 0.377, p = 0.08; r = 0.212, p = 0.34). In eyes with XFG, the IPL thickness correlated with the visual field MS scores (r = 0.572, p = 0.0007), similar to the correlation of GCL (r = 0.585, p = 0.0005) thickness with visual field scores.
conclusionsSegmented analysis of the macular IPL thickness presented a significant correlation with the 10-2 visual field scores not only in eyes with XFG but also in eyes with XFS. With respect to early dendritic/synaptic alterations in animal models, larger and longitudinal studies are encouraged to determine the predictive value of the IPL thickness for conversion of XFS to XFG.
