When Seizures Lead to the Incidental Finding of Silicone Oil Migration.
Article in Cureus, 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
Silicone oil, commonly used as a temporary intraocular tamponade in retinal detachment repair, may have retrobulbar migration as a possible complication of the procedure to the cerebral ventricles. This report presents the case of a 73-year-old male patient with multiple cardiovascular risk factors and diffuse atherosclerotic disease who underwent vitrectomy of the left eye several years earlier due to retinopathy and was diagnosed through retrospective analysis of all cerebral imaging studies, with the migration of silicone oil particles, from the vitreous humor of the eye to the intraventricular space. He was admitted due to transient altered consciousness in the context of a probable seizure, with acute hyperdensity in the temporal horn of the left lateral ventricle observed in the cranial computed tomography (CT), suggestive of hemorrhage, along with signs of prior hemorrhage in the frontal horn of the same ventricle. The follow-up CT showed reabsorption of the hyperdensity seen in the admission CT, with a new hyperdense focus observed in the frontal horn of the same ventricle, a location matching that was seen in imaging studies performed eight years earlier. This focus exhibited a similar morphology, consistent with the mobilization of hyperdensity particles, according to the patient's head movements, which, considering the patient's medical history, led to the diagnosis of intraventricular migration of the silicone oil used in tamponade of the retinal detachment repair. The aim of this report is to describe a rare occurrence of intraocular silicone oil migration into the cerebral ventricles, which may be misinterpreted as intraventricular hemorrhage. This case highlights the importance of obtaining a detailed medical history with an integrative perspective and underscores the value of interdisciplinary collaboration in the diagnostic process.
