Successful Management of Herpes Simplex Keratitis With Oral Valganciclovir in Patients Unresponsive or Allergic to Conventional Antiviral Therapy.
Article in Cornea, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
purposeTo describe 4 cases of presumably immunocompetent patients with herpes simplex virus (HSV) keratitis unresponsive (n = 3) or allergic (n = 1) to conventional antiviral therapy that improved with oral valganciclovir treatment.
methodsRetrospective case series of 4 patients with HSV keratitis treated with oral valganciclovir between March 2016 and June 2018.
resultsWe reviewed the records of 4 patients with recurrent epithelial HSV keratitis. Three patients were on antiviral prophylaxis because of a history of HSV keratitis. All patients were on oral acyclovir, valacyclovir, and/or famciclovir treatment with/without topical antiviral therapy for 4 to 6 months for prophylaxis and/or recurrent dendriform epithelial keratitis. While 3 patients had recurrent episodes during their active prophylaxis with oral antiviral therapies, one patient had a recurrence after she discontinued her oral prophylactic antiviral therapy due to recurrent self-reported allergic reactions. The patients presented with recurrent dendriform epithelial keratitis despite conventional antiviral therapy. We initiated oral valganciclovir 900 mg twice a day for 10 days as a treatment dose, followed by 900 mg daily for prophylaxis. The corneal epithelium subsequently healed within the first 2 weeks in all patients. The mean follow-up time for patients on valganciclovir prophylaxis was 8 months (range: 6-12 months), and none of the patients presented with any further recurrences.
conclusionsIn case of treatment-related side effects or failure with conventional antiviral therapies, oral valganciclovir may present an alternative for the treatment and prophylaxis of HSV keratitis.
