Phaeoisaria sp. fungal keratitis resembling corneal rust residue: a case report.
Article in BMC ophthalmology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundFungal keratitis can develop after plant injury or after prolonged glucocorticoid use. Typical manifestations include corneal infiltrates, satellite lesions, plaques, and an immune ring. Some cases exhibit atypical signs, requiring reliance on etiological examination. Notably, fungi previously deemed nonpathogenic to humans can cause keratitis with rare clinical manifestations. This report details the clinical signs and successful treatment outcomes of keratitis caused by Phaeoisaria sp. CASE PRESENTATION: A 51-year-old man visited the ophthalmology clinic with ongoing eye pain and a history of corneal iron foreign body removal two months earlier. Examination revealed a brownish ulcer with clear borders, swelling, and redness, indicating the presence of rust. Although the initial cultures were negative, a rare fungus called Phaeoisaria sp. was eventually identified as causative agent. The patient completed six weeks of antifungal treatment and showed no signs of recurrence at the 7-month follow-up visit.
conclusionsPatients with a history of corneal foreign bodies should also be informed of the possibility of atypical corneal fungal infection.
