Comparison of gas and silicone oil tamponades for inferior quadrant recurrence in patients undergoing pars plana vitrectomy for rhegmatogenous retinal detachment.
Article in International ophthalmology, 2025. 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 compare gas and silicone oil (SO) tamponades on inferior quadrant recurrence in patients undergoing pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD).
methodsThis retrospective study included patients who underwent PPV with intraocular tamponade for RRD between May 2019 and February 2023. Patients with proliferative vitreoretinopathy (PVR) grade C1 or lower and at least three months of follow-up were included. Patients were divided into two groups based on the use of gas or SO tamponade. Comparisons were made regarding age, gender, lens status, intraocular pressure (IOP) changes, recurrence rates, tear localization, number of surgeries, and final anatomical and visual success.
resultsA total of 121 eyes of 121 patients were included, 59 in the gas group and 62 in the SO group. Inferior quadrant recurrence occurred in 7 (11.2%) patients in the gas group and 6 (10.1%) in the SO group (p = 0.842). The mean time to recurrence was 24 ± 11.5 days for the gas group and 31.3 ± 9.8 days for the SO group (p = 0.345). Mean BCVA improved significantly in both groups (p < 0.01). The mean number of surgeries was 1.16 ± 0.48 in the gas group and 2.18 ± 0.57 in the SO group (p < 0.001). IOP elevation requiring treatment occurred in 15.3% of the gas group and 34% of the SO group (p = 0.024).
conclusionThere was no significant difference in aspect of inferior quadrant recurrence between gas and SO in patients without advanced PVR. Silicone oil lead to additional surgeries and complications.
