Incidence and risk factors of postoperative visual loss in cardiac surgery in the United States from the national inpatient sample 2013 to 2022.
Article in Journal of cardiothoracic surgery, 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
backgroundPostoperative Visual Loss (POVL), a rare but severe complication, occurs more often in cardiac surgery. It leads to significant disability, emotional distress, and healthcare costs. In the U.S., where cardiac surgery is common, POVL is challenging to treat, thus identifying characteristics associated with POVL is key to identifying at-risk patients. Uncovering risk factors and prevention strategies for this serious event is crucial. This study aims to assess incidence trends and correlate patient and perioperative factors with POVL.
methodsA retrospective study was conducted using the National Inpatient Sample (NIS) database from 2013 to 2022, the largest fully paid hospital care database in the United States. The patient’s demographics, hospital characteristics, length of stay (LOS), total costs, in-hospital mortality, preoperative comorbidities, and postoperative complications were documented. Logistic regression analysis was performed to identify the risk factors and associated factors of POVL.
resultsA total of 544,757 patients who underwent cardiac surgery were identified from the NIS database between the period of 2013 and 2022. The incidence of POVL was 1 in 1000 surgeries, or 0.10%, with no significant linear upward or downward trend. Patients with POVL after cardiac surgery presented prolonged LOS and increased hospitalization costs. Preoperative risk factors associated with postoperative POVL included the 18–49 age group, admission to a teaching hospital, anemia, paralysis, peripheral vascular disorders, valvular disease, and weight loss. Additionally, POVL was also associated with in-hospital complications including blood transfusion, acute renal failure, pulmonary embolism, stroke, and arrhythmia. Conversely, the protective factors included black, Hispanic, Asian, and Pacific Islander ethnicity, elective hospital admissions, the south region of the hospital, and hypertension.
conclusionsThis nationwide study identified a relatively low incidence of POVL after cardiac surgery and shows no significant trend. In the absence of effective treatment, it is crucial to identify high-risk patients, implement well-planned anesthetic management, and conduct postoperative vision assessments to prevent visual loss.
