A mobile system for whole eye perfusion supporting retinal function and surgery.

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
Introduction: The use of human donor tissue has the potential to accelerate translational research and support the development of effective human medicines. However, post-mortem sample degradation and the loss of anatomical context limits the utility of primary tissue. Methods: Here, an ex vivo perfusion platform, the Advancing Straight-to-Human Eye Research (ASTHER) system, was designed to perfuse whole eyes with autologous blood to support ex vivo viability. The system was designed for portability and compatibility with modern surgical techniques. Results: Feasibility trials of ophthalmic artery cannulation, arterial perfusion, retinal imaging, and electroretinography with the ASTHER platform were performed. Discussion: Qualitative imaging and electroretinography confirmed post-enucleation retinal blood supply and neuronal function in perfused Yucatan mini pig eyes. Retinal surgery was performed in perfused eyes. A pilot study showed the applicability of the minipig enucleation and perfusion protocol in donated human tissue. Future validation studies of the ASTHER platform will quantify perfused tissue structure and function.
