Effect of Prone Position on Intraocular Pressure in Patients Undergoing Nonocular Surgery: A Systematic Review.
Review in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07067008 (Measurement of Intraocular Pressure), which is not on this map. Cited by 2 papers.
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.

Abstract
Postoperative vision loss is a rare complication following surgery in prone positioning. Waking with loss of visual acuity after an elective nonocular surgery is a catastrophic event, not only for the patient but also for the physicians. The specific pathogenesis of postoperative vision loss remains unknown in most cases. This systematic review aims to investigate the effect of prone positioning on intraocular pressure in patients undergoing surgeries and alert physicians to the potential vision loss in the postoperative period. A meticulous research of PubMed, Scopus, and Google Scholar databases was conducted for relevant articles published between January 2012 and September 2023. All relative prospective, retrospective, comparative, and non-comparative studies that investigated prone position and its effect on intraocular pressure during surgery were considered eligible for inclusion in our systematic review. A total of eight studies comprising 649 patients who underwent nonocular surgery under prone positioning were reviewed. Most patients underwent spine surgery with total intravenous anesthesia. The device most frequently used for intraocular pressure measurement was Tono-Pen® XL (Medtronic plc, Galway, Ireland). None of the patients suffered from visual loss postoperatively. Only three patients had vision disturbances after surgery due to prone positioning. There was also a significant rise in intraocular pressure from the supine to the prone position. There is a need to identify crucial factors for the prevention of postoperative vision loss.
