Relationship between visual function and macular microstructure in highly myopic patients undergoing surgery for rhegmatogenous retinal detachment.

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
objectiveTo analyze the relationship between visual function and macular microstructure in highly myopic patients undergoing surgery for rhegmatogenous retinal detachment (RRD).
methodsFifty-eight highly myopic patients treated in the Baoding No. 1 Central Hospital between December 2021 and September 2023 were selected as the research participants for retrospective analysis. All patients were complicated with RRD and underwent retinal reattachment surgery at Baoding No. 1 Central Hospital after diagnosis. Best-corrected visual acuity (BCVA) examinations were performed before and 3 months after surgery, and visual field mean sensitivity (MS) and fixation stability (FS) were measured by microperimetry. Additionally, changes in postoperative macular microstructure and micro blood flow were determined by optical coherence tomography (OCT), and their correlations with visual function were analyzed.
resultsPatients showed reduced BCVA, MS, and FS after surgery (all P<0.05), with 70.69% of them presenting with macular microstructural changes, mainly ellipsoid zone disruption and external limiting membrane disruption. Patients with macular microstructural changes exhibited significantly decreased BCVA, MS, and FS than those without (all P<0.05). In terms of micro blood flow, the BCVA, FS, and MS of patients with macular microstructural changes were negatively correlated with the foveal avascular zone (FAZ) area but were positively related to FAZ morphological index, PSCP, and VSCP (all P<0.05).
conclusionsChanges in patients' visual function after surgery for RRD can be effectively evaluated by observing the macular ellipsoid, the integrity of the external limiting membrane, and the alterations in micro-blood flow, enabling the formulation of early and targeted interventions.
