Intravitreal cotrimoxazole as adjuvant therapy for active ocular toxoplasmosis: a case series and literature review.
Article in Journal of ophthalmic inflammation and infection, 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
backgroundOcular toxoplasmosis represents the most common cause of posterior uveitis worldwide and remains a major cause of visual morbidity, particularly among young and immunocompetent individuals. The purpose of this study is to assess the efficacy and safety of combined intravitreal trimethoprim/sulfamethoxazole and dexamethasone with concurrent systemic cotrimoxazole and oral corticosteroids in patients with active Toxoplasma chorioretinitis.
methodsThis retrospective interventional case series included a total of seven eyes from seven consecutive patients with active necrotizing toxoplasma retinochoroiditis and dense vitritis involving zone 1. All examinations were performed by a uveitis specialist. Each patient received a single intravitreal injection of trimethoprim/sulfamethoxazole and dexamethasone, in addition to systemic cotrimoxazole and prednisolone. Clinical evaluation included best-corrected visual acuity (BCVA), intraocular pressure (IOP), grading of ocular inflammation, and fundus examination. Patients were followed weekly for one month and subsequently on a monthly basis for three months.
resultsAll patients demonstrated a rapid reduction in inflammation and lesion size, accompanied by improvement in BCVA, achieving a final visual acuity of 8/10 to 10/10 at one month. No ocular or systemic complications, IOP elevation, or recurrence were observed during the three-month follow-up period.
conclusionAdjuvant intravitreal cotrimoxazole therapy appears to be a safe and effective option for vision-threatening ocular toxoplasmosis, providing rapid disease control and excellent visual outcomes.
