Anterior Chamber Sulfur Hexafluoride Injection for Hypotony Management: Case Report and Literature Review.
Article in Case reports in ophthalmology. 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
Introduction: Hypotony is a potentially vision-threatening condition that may persist despite conservative management, often necessitating surgical or interventional treatment. We present a case where a minimally invasive injection of 100% sulfur hexafluoride (SF6) into the anterior chamber (AC) successfully reversed refractory hypotony secondary to ciliary body shut-down. Case Presentation: A 72-year-old male with advanced pseudoexfoliation glaucoma and a nonfunctioning trabeculectomy presented with hypotony, decreased vision, a deep AC, and 360° serous choroidal effusions. After excluding other etiologies, ciliary body shutdown was presumed. Conventional measures, including topical steroids, cycloplegia, and AC viscoelastic injection, failed to restore intraocular pressure (IOP). Given the refractory course, 100% SF6 gas was injected into the AC. Within 24 h, a reverse pupillary block developed, leading to a rapid IOP increase. The gas fully reabsorbed within weeks, with resolution of the choroidal effusions and normalization of IOP. At 6 months, the patient maintained stable IOP and visual acuity without further intervention. Conclusion: This case highlights the potential of SF6 gas injection as a minimally invasive and effective treatment for refractory hypotony, even when the underlying mechanism is not over-filtration.
