Intravitreal C3F8 versus SF6: effects on corneal tomography parameters and intraocular pressure in vitreomacular traction treatment.
Article in International ophthalmology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeInvestigate the effect of intravitreally administered C3F8 and SF6 expansile gases on corneal tomographic parameters and intraocular pressure (IOP) for the treatment of vitreomacular traction (VMT) with pneumatic vitreolysis (PV).
methodsPatients who underwent intravitreal C3F8 or SF6 injection for VMT treatment were assessed. Each eye underwent a complete ophthalmic examination pre-operation and 1 h, 6 h, 24 h post-operation, including IOP assessment and corneal tomographic analysis with Pentacam.
resultsIn both groups, 30 eyes were included in study. Mean IOP in C3F8 group was 16.2 ± 2.7 mmHg pre-operation, 28.5 ± 14.1 mmHg at 6 h and 24.0 ± 2.5 mmHg at 24 h post-operation. Mean IOP in SF6 group was 16.1 ± 3.3 mmHg pre-operation, 29.6 ± 13.1 mmHg at 6 h and 16.7 ± 2.4 mmHg at 24 h post-operation. Increase in IOP was statistically significant at 6 and 24 h in the C3F8 group, whereas the statistically significant increase was only at 6 h in the SF6 group(p < 0.05). Anterior chamber angle showed statistically significant narrowing at 6 and 24 h in the C3F8 group, while statistically significant narrowing was observed only at 6 h in the SF6 group(p < 0.05). There was a statistically significant increase in pachymetry measurements at apex and thinnest location, and corneal volume values at post-operative 1 and 6 h in both groups compared to pre-operative values(p < 0.05).
conclusionPV with SF6 should be preferred for VMT treatment in angle closure glaucoma, angle closure suspect and advanced glaucoma patients, since the increase in IOP due to angle narrowing in the C3F8 group remained at 24 h.
