The long-term outcome of eyes with unexplained visual loss after gas tamponade for macula-on retinal detachment.
Article in Retinal cases & brief reports, 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 analyze the long-term outcome of eyes suffering from unexplained visual loss after gas tamponade for primary macula-sparing rhegmatogenous retinal detachment (RRD).
methodsCross-sectional analysis of all eyes with macula-on RRD experiencing an unexplained loss of vision after gas reabsorption that were treated and followed from 2010 to 2019. The investigational work-up included: best-corrected visual acuity (BCVA), clinical examination, spectral-domain optical coherence tomography (SD-OCT) and automated computerized perimetry.
resultsThe 9 eyes of the 9 patients were analyzed after 5.9±2.4 years. BCVA improved by 0.54±0.50 logMAR from baseline, achieving a final value of 1.17±0.52 logMAR (∼20/320; p=0.0115). The thicknesses of the macula, of the macular ganglion cells and of the retinal nerve fiber layers were unchanged compared to the baseline, as well as the rate of ellipsoid zone defects (22.2%). The proportion of eyes with microcystoid macular edema (MME) significantly decreased to 44.4% (p=0.0294). Perimetry mean deviation increased from a baseline value of -18.06±2.72 to -17.23±2.29 dB (p=0.0390), with an unchanged pattern standard deviation (p=0.1289). In general, a reduction of the scotomata relative depth from baseline was evident in all eyes.
conclusionsEyes with macula-on RRD suffering from unexplained visual loss after gas reabsorption, despite disclosing an overall unchanged structural macular morphology, showed a moderate, but significant, visual and perimetric improvement in the long-term.
