Description
Smithee and co-authors used gaze mapping to watch where clinicians look during nasal endoscopy. That camera exam is key to spotting sinus disease. They asked whether spotting mucus needs steady visual attention. Sixteen people reviewed endoscopy images with 336 marked areas of interest. The areas covered both normal anatomy and abnormal spots.
Mean gaze fixation on mucus areas was only 404 milliseconds. Normal anatomy drew 1,045 milliseconds in the same image set. The 600 millisecond threshold thought needed for conscious noticing was reached in just 22.7 percent of mucus viewings. For normal anatomy the figure was 57.4 percent overall. Among abnormal findings, mucus drew shorter looks, 295 milliseconds. Scars, masses, or redness hit 612 milliseconds of gaze. The authors conclude most mucus findings never receive enough gaze to be noticed. That helps explain the very low match between raters.
