Intraocular Pressure Control in Vitreoretinal Surgical Systems.
Article in Clinical ophthalmology (Auckland, N.Z.), 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
Purpose: A comparison was made between the Constellation Patients and Methods: An acrylic eye model was connected to a vitrectomy probe, an infusion cannula, and a pressure transducer. The Constellation and EVA systems were tested using 25-gauge probes in vacuum mode with vacuum settings at 250, 450, and 650 mmHg. The target IOP was 30 mmHg. Average IOP was assessed before aspiration (initial IOP), during vitreous removal (vitreous IOP), and after vitreous removal and replacement with Alcon's BSS Results: Using Constellation's IOP control, target IOP (30±2.5 mmHg) was maintained 93%, 74%, and 63% of the time at 250, 450, and 650 mmHg of vacuum, respectively. At 650 mmHg, initial IOP, vitreous IOP, and BSS IOP were 30.18±0.18, 30.99±0.66, and 31.55±1.38 mmHg. Using EVA with AIC, target IOP was maintained 16%, 17%, and 23% of the time at 250, 450, and 650 mmHg of vacuum. At 650 mmHg, initial IOP, vitreous IOP, and BSS IOPs were 30.54±0.08, 44.62±1.24, and 29.92±0.72 mmHg (P<0.0001). Conclusion: When confronted with dynamic fluid conditions during vitreous removal, the Constellation system with IOP control automatically maintained stable IOP in the target range 63% to 93% of the time at different vacuum settings versus ≤23% of the time with the EVA system with AIC.
