Severe Lower Gastrointestinal Bleeding Leading to Bilateral Non-arteritic Anterior Ischemic Optic Neuropathy: A Rare Systemic Complication.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Lower gastrointestinal bleeding (LGIB) is a common clinical emergency; however, systemic complications such as bilateral non-arteritic anterior ischemic optic neuropathy (NAION) are exceedingly rare. We report the case of a 78-year-old male with a history of hypertension and hyperlipidemia who developed progressive bilateral vision loss following hospitalization for severe LGIB. His hemoglobin nadir dropped to 6.9 g/dL from a baseline of 11 g/dL, prompting transfusion with one unit of packed red blood cells. Arteritic causes were ruled out through appropriate workup. Imaging demonstrated significant carotid and vertebrobasilar atherosclerotic disease, and ophthalmologic evaluation confirmed bilateral NAION. This case highlights the potential for ischemic optic neuropathy in the setting of acute anemia and underlying vascular insufficiency. Clinicians should maintain a high index of suspicion for ischemic complications following severe gastrointestinal bleeding, particularly in high-risk patients.
