Multidrug-resistant Acanthamoeba keratitis caused by the T4 Genotype: A case report.
Article in Parasitology research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
This report describes the case of a 28-year-old woman, who presented with a two-week history of severe ocular pain and photophobia in her right eye. She was a soft contact lens wearer with no history of ocular trauma or systemic illness. Ophthalmic examination revealed conjunctival hyperemia, epithelial irregularities, and a developing ring-shaped stromal infiltrate. In vivo confocal microscopy demonstrated double-walled hyperreflective cysts, and culture followed by PCR and sequencing confirmed the presence of Acanthamoeba T4 genotype. Despite intensive treatment with topical polyhexamethylene biguanide, chlorhexidine, propamidine, and voriconazole, as well as oral miltefosine, the infection progressed, leading to stromal necrosis. The patient underwent two therapeutic penetrating keratoplasties; however, the disease continued to advance, eventually resulting in phthisis bulbi and permanent vision loss. This case highlights the potential for aggressive, clinically refractory Acanthamoeba keratitis caused by the T4 genotype, emphasizing the importance of early diagnosis, vigilant monitoring, and timely surgical intervention in resistant cases.
