Eye Tracking in Laryngology

Not Applicable

Completed

• Conditions: Healthy
• Interventions: Other: Eye Tracking Technology Sensor

• Registration Number: NCT05034575
• Lead Sponsor: Mayo Clinic

Brief Summary

The purpose of this study is to assess whether eye-tracking technology can be used to differentiate the visual gaze patterns of experienced and novice laryngoscopists while reviewing prerecorded laryngeal videos with both normal and abnormal findings and to characterize any differences arising between level of training groups.

Detailed Description

Novice and experienced participants will be recruited to take part in this study. Novices include medical students without practical experience in otorhinolaryngology and resident physicians at different stages in training. Trainees, residents and experts from fields of gastroenterology and pulmonology will also be included. The experienced group will be defined as consultants and speech pathologists.

This study will look at multiple areas within otolaryngology including laryngology, rhinology, facial plastic surgery, head and neck oncology, and otology. Participants will view prerecorded videos and/or still pictures absent of patient identifiers.

There will be two tasks each taking approximately 10 minutes. Task order will be alternated between subjects with one task asking participants to view 7 still images from video laryngoscopy examinations. After each image participants will rate how likely the image is to represent glottic cancer and what portion of the image they deemed most important to their decision. For the second task, participants will be asked to view a 5 second video of a flexible laryngoscope exam, after which, they will be asked to identify the presence and side of vocal fold paralysis as well as note the location they deemed most important to their decision.

Arm && Interventions

Group	Intervention	Description
Novice and experienced medical personnel	Eye Tracking Technology Sensor	Participants will be asked to complete two tasks each taking approximately 10 minutes while wearing eye-tracking technology to understand focus of gaze during laryngeal endoscopy and stroboscopy interpretation.

Primary Outcome Measures

Name	Time	Method
Time to Fixation Fixation Point	15 minutes	Defined as the temporary suspension of eye movement (80ms) on a specific point (≤ 30 pixels) within the field of view.
Percent of Fixation Time on pre determined area of interest	15 minutes	Defined as the percent of total gaze time on area of interest
Count of Fixations	15 minutes	Number of times observer returns gaze to area of interest
