Prevalence and clinical characteristics of Terson syndrome among survivors of aneurysmal subarachnoid hemorrhage: a nationwide study in Japan.
Article in Japanese journal of ophthalmology, 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
purposeTo investigate the characteristics of Terson syndrome (TS) among survivors of aneurysmal subarachnoid hemorrhage (aSAH). STUDY
designRetrospective study
methodsUsing the Japanese Diagnosis Procedure Combination database, we identified patients diagnosed with aSAH at admission between July 1, 2010 and March 31, 2023 in Japan. The prevalence of TS in aSAH survivors was examined, along with comparisons of patient backgrounds between survivors with TS and those without TS. We compared the characteristics and outcomes in patients with TS who underwent vitrectomy with those in patients who did not, and analyzed the laterality of the surgery.
resultsAmong 143,058 patients with aSAH, 104,576 (73.1%) survived. TS was diagnosed in 860 (0.8%) survivors. The patients with TS were younger (mean [standard deviation, SD] age: 53.3 [11.4] vs 64.0 [14.6] years) than those without TS. Among the patients with TS, 243 (28.3%) patients underwent vitrectomy during hospitalization, with a median interval of 38 days from admission to surgery. Of the patients with TS who underwent vitrectomy, 160 (66.4%) and 81 (33.6%) patients underwent unilateral and bilateral vitrectomy, respectively.
conclusionIn this retrospective study, the prevalence of TS among aSAH survivors was less than 1%. Vitrectomy was performed in approximately one-third of the patients with TS, with one-third of these patients undergoing bilateral surgery during hospitalization.
