Summary
Visual gaze patterns did not differ by experience level when identifying vocal cord lesions. However, novices were less accurate in rating cancer likelihood for infectious laryngitis compared to experts.
Area of Science:
- Otolaryngology
- Medical Education
- Ophthalmology
Background:
- Accurate diagnosis of vocal cord lesions relies on visual interpretation.
- Experience level may influence diagnostic accuracy and visual search strategies.
Purpose of the Study:
- To evaluate visual gaze patterns and cancer identification accuracy in vocal cord lesions across different experience levels.
- To determine if visual search strategies differ between novices and experts when assessing vocal cord pathology.
Main Methods:
- Thirty-one participants (novice to expert) viewed vocal cord pathology images.
- Participants rated the likelihood of cancer.
- Eye-tracking data collected to analyze fixation patterns (first, longest, most).
Main Results:
- No significant differences in visual gaze targets (area of interest) were observed among experience groups.
- Novice participants were significantly more likely to underestimate cancer risk in infectious laryngitis compared to experienced groups.
- Cancer likelihood ratings for other lesions did not differ significantly by experience level.
Conclusions:
- Visual search patterns do not significantly differ across experience levels when evaluating vocal cord pathology.
- The similar appearance of benign and malignant lesions may explain diagnostic discrepancies.
- Further research with larger cohorts is needed to refine understanding of gaze patterns in vocal cord lesion diagnosis.
