Can intravitreal injections with higher volume cause higher intraocular eye pressure? Considerations for anti-complement injections in normal and glaucomatous eyes.
Article in International journal of retina and vitreous, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled it.
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
The approval of Syfovre® (pegcetacoplan) and Iverzay® (avacincaptad pegol) for the treatment of geographic atrophy (GA) marks a significant advancement in retinal disease therapy, offering both complement 3 and complement 5 inhibitors. With this breakthrough, an increase in intravitreal injections (IVI) is expected to treat GA, raising questions about potential effects on intraocular pressure (IOP). This concern is exacerbated by the larger injection volume required for GA treatment, potentially impacting IOP. Previous studies have shown that IVI can lead to a temporary increase in IOP with a 0.05 ml injection. This transient elevation is challenging to manage with glaucoma drops, and a preventive approach, such as paracentesis immediately before IVIs, may be more effective. Despite concerns, clinical significance and long-term effects of IOP changes with a 0.05 ml injection remain uncertain. To address these concerns, routine evaluations including macular optical coherence tomography (OCT), fundus autofluorescence, IOP measurements, and retinal nerve fiber layer OCT before the first IVI with avacincaptad pegol and pegcetacoplan are recommended to detect potential changes early. Further research is needed to determine the extent to which IOP changes impact GA patients and whether cumulative effects occur with repeated IVIs, especially in those with additional eye conditions.
