Evaluation of OCT image quality in gas-filled eyes using four OCT devices.

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 compare optical coherence tomography (OCT) image quality obtained on postoperative day 1 under intraocular gas tamponade using four OCT devices, including two swept-source OCT (SS-OCT) and two spectral-domain OCT (SD-OCT) systems.
methodsThis retrospective study included 30 consecutive eyes of 30 patients who underwent pars plana vitrectomy with gas tamponade between June 2025 and February 2026. On postoperative day 1, OCT imaging was performed using four devices: two SS-OCT systems (DRI OCT Triton and PLEX Elite 9000) and two SD-OCT systems (RTVue XR Avanti and SPECTRALIS OCT). OCT image quality was graded using a 5-point scale by two masked graders, and the mean score was used for analysis. The primary analysis compared image quality scores among devices in 25 eyes with macular hole using the Friedman test with Bonferroni correction.
resultsThe mean patient age was 70.0 ± 8.7 years, and 13 patients (43.3%) were male. The median (interquartile range) image quality scores in macular hole cases (n = 25) were 5.0 (4.0-5.0) for Triton, 5.0 (4.0-5.0) for Plex Elite, 4.0 (4.0-5.0) for Avanti, and 2.0 (1.0-3.0) for Spectralis. Image quality scores differed significantly among the four devices (Friedman test, p < 0.001).
conclusionsUnder intraocular gas tamponade, the SD-OCT device Avanti demonstrated relatively preserved image quality. These findings suggest that device-specific acquisition characteristics, beyond wavelength differences, substantially influence OCT image quality in gas-filled eyes. These findings may assist clinicians in selecting appropriate OCT devices for reliable postoperative assessment under gas tamponade.
