Prevalence and predictors of metamorphopsia after successful vitrectomy surgery for macula-off rhegmatogenous retinal detachment.
Article in La Tunisie medicale, 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
aimTo estimate metamorphopsia prevalence, predictors and etiologies in patients operated for rhegmatogenous retinal detachment (RRD) with detached macula with successful results.
methodsRetrospective study including 50 eyes of 50 patients who underwent pars plana vitrectomy for RRD with detached macula with standard silicone oil (SO) tamponade. Patients who had successful surgery with durable anatomic reapplication of the retina after SO removal were included. Patients were examined on day 1, day 7,1 month, and 3 months after surgery. Best corrected visual acuity, Amsler grid, fundus biomicroscopy, Spectral Domain Optical Coherence Tomography (SD-OCT) and fundus auto-fluorescence (FAF) were performed in all patients after surgery. Structural abnormalities such as macular folds, macular epiretinal membrane, cystoid macular edema, and foveal disruption of the ellipsoid layer were observed on SD-OCT. Macular displacement was identified on FAF.
resultsWe identified metamorphopsia as post-operative visual impairment in 27 patients among 50 (54%). Clinical assessment found that a delay > 7 days between symptoms and surgery (p < 0.001), more than 2 detached quadrants (p=0.012), and stage C of proliferative vitreoretinopathy (p=0.035) were associated to metamorphopsia. Regarding multimodal imaging findings, only macular folds and macular displacement were significantly correlated with the occurrence of postoperative metamorphopsia (p <0.001).
conclusionMetamorphopsia is a common complaint after vitrectomy for RRD. Macular rotation and folds would be the main causes after complete and durable reapplication of the retina.
