Quantifying retinal oxygenation and metabolism by phosphorescence lifetime imaging.
Review in Experimental eye research, 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
The retina is a highly metabolically active tissue, requiring adequate availability of oxygen and other metabolites to generate energy for cellular survival and visual function. Retinal hypoxia has been implicated in several common retinal diseases and associated with the development of vision-threatening pathologies. Since the level of hypoxia determines processes that are activated for either cell survival or death, knowledge of retinal oxygenation is essential. This article reviews depth-resolved quantitative measurements of retinal vascular and tissue oxygen tension in rodents using the technique of phosphorescence lifetime imaging. Furthermore, retinal oxygen metabolic biomarkers were quantitatively derived from oxygen tension measurements and shown to be altered under challenged physiological and pathological conditions. Application of phosphorescence lifetime imaging can be useful for advancing knowledge of retinal ischemia pathophysiology and identifying physiological biomarkers to monitor progression and evaluate therapeutic interventions in animal models of human retinal diseases.
