Occupational exposure to video display terminals: a systematic review of ocular and visual health effects and associated risk factors.
Synthesis in Journal of occupational health, 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
objectivesTo synthesize ocular and visual effects caused by occupational exposure to video display terminals (VDTs). Additionally, we aimed to identify the occupational and nonoccupational risk and protective factors related to these effects, and to propose a conceptual mapping to manage affected workers.
methodsThe review protocol was registered in PROSPERO and the systematic review was conducted following PRISMA guidelines. A search of MEDLINE, Scopus, and Web of Science was performed to identify studies published between January 2006 and December 2023. Only primary studies were included. Study quality was assessed using a critical appraisal tool based on STROBE statements for cross-sectional studies and the Scottish Intercollegiate Guideline Network checklist for randomized controlled trials and cohort and case-control studies. Low-quality studies were excluded.
resultsEighty-five articles were included, 50 of high quality. The main ocular and visual effects were computer vision syndrome, dry eye disease, and other isolated signs and symptoms. The main risk factors were the daily hours of VDT exposure, female gender, use of ophthalmic or contact lenses, increasing age, altered lighting conditions, and job seniority. Breaks, adequate workstation design, and ergonomic improvements were the main protective factors. Psychosocial factors and lifestyle behaviors also may influence ocular and visual health at work.
conclusionsWide methodological variations were found, making it difficult to compare studies. Nevertheless, an evidence-informed conceptual mapping has been proposed that could be used as a starting point to guide preventive measures in VDT work settings. Further research with appropriate epidemiological designs is needed to establish causal relationships or determine temporal sequences between exposures and outcomes.
