An analysis of heavy silicone oil treatment for inferior proliferative vitreoretinopathy.
Article in BMC ophthalmology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
purposeProliferative vitreoretinopathy (PVR) is a complication of retinal detachment which requires multiple vitreoretinal surgical interventions and frequent use of oil endotamponade. In this study, we conducted an in-depth analysis of complications associated with the use of heavy silicone oil in the management of inferior PVR.
methodsA retrospective cohort study of 20 eyes that underwent vitrectomy for inferior PVR with use of heavy silicone oil (Densiron 68) between March 2021 and October 2022 at Oxford Eye Hospital. Complications were classified into major categories relating to intraocular pressure, inflammation, lens, and oil emulsification/migration. Visual outcomes and surgical success rate were also evaluated.
resultsFill-induced pressure spikes (> 30 mmHg) within 14 days post-surgery were common after Densiron tamponade, especially in patients previously on glaucoma drops. The number of glaucoma drugs were increased in 45% of patients during Densiron tamponade. In 20% of cases, an increased medication was continued long-term after Densiron removal. Significant cataract progression occurred in all phakic patients. In 25% of pseudophakic cases, posterior capsule opacification was noted. Inflammatory complications, such as anterior uveitis, were rare and any cystoid macular oedema was transient. No unexplained acute loss of vision following Densiron removal was encountered. The anatomical success rate at 30 days after Densiron removal was 70%. The mean (± SD) best-corrected visual acuities were 1.04 (± 0.79), 0.85 (± 0.62) and 0.50 (± 0.51) logMAR prior, during and after Densiron tamponade, respectively.
conclusionThe outcomes in this cohort treated with Densiron 68 were comparable to previously reported anatomical and functional results in cases with inferior PVR. IOP and lens-related complications require additional treatment during or after Densiron tamponade. Inflammatory complications rarely occurred over tamponade durations of around three months.
trial registrationAnalyses were conducted as an internal quality improvement audit and as such did not require external IRB review.
