[Glaucoma: ecological comparison of disposable and reusable measuring bodies for applanation tonometry according to Goldmann].
Article in Die Ophthalmologie, 2026. 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
backgroundThe measurement of intraocular pressure (IOP) according to Goldmann is the gold standard for tonometry in glaucoma diagnostics. The use of reusable instead of disposable products has the potential to reduce the environmental impact and make a positive contribution to the circular economy.
objectiveThe aim of this study was to analyze the ecological added value of reusable in comparison to disposable measuring devices for Goldmann applanation tonometry in order to quantify the potential reduction in environmental impact in hospitals and medical practices. MATERIAL AND
methodsTo assess the potential environmental impact of the use of disposable and reusable measuring instruments for applanation tonometry according to Goldmann, a life cycle assessment was conducted in accordance with ISO standards 14040/44. The product-specific greenhouse gas savings were then scaled as an example for a glaucoma consultation at Erlangen University Hospital and for Germany as a whole. RESULTS AND
conclusionThe results show that 44% of the greenhouse gas emissions associated with the measuring bodies can be saved by switching from disposable to reusable measuring bodies. In absolute terms, the greenhouse gas savings amount to 5.6 g CO
