Histopathology of Hydrolyzed MIRAgel Scleral Buckles.
Article in Ocular oncology and pathology, 2021. 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
introductionThe goal of this study was to histopathologically evaluate the appearance of degrading MIRAgel scleral buckles so that they can be reliably distinguished by ophthalmic pathologists from other foreign materials.
methodsRetrospective chart review and histopathologic study with special stains, including Alcian blue, periodic acid-Schiff, Masson's trichrome, and Perls' Prussian blue for iron, of 4 cases between 2017 and 2019.
resultsHydrolyzed MIRAgel scleral buckles from 4 patients had a consistent histopathologic appearance. They had a honeycomb structure with the walls of the lattice ranging from distinct to poorly defined. The walls of the lattice were positive for Alcian blue, while the contents of each cell contained periodic acid-Schiff-positive material. Other special stains were not as valuable in highlighting the material. DISCUSSION: Although the capsules of MIRAgel scleral buckles have been well studied, the material itself has not been. While clinical history and radiographic appearance are often diagnostic of a hydrolyzed MIRAgel scleral buckle, there are instances of preoperative ambiguity where histopathologic confirmation can be useful.
conclusionsMIRAgel scleral buckles have a distinct histopathologic appearance that can be readily distinguished from that of other foreign materials.
