Background
Eye tracking technology has been utilized to assess the severity and document the improvement in the treatment of autism. In this pilot we have applied this to the analysis of results following facial aesthetic surgery. Quantitative data including fixation times, and sequence of visual scanpath are obtained to compare pre and postoperative changes post rhytidectomy. In addition, as studies show that a face is scanned in a central triangle pattern of eyes, nose and mouth, we study if this scan path is altered.
Methods
Five volunteers viewed randomized images of six patients pre and post rhytidectomy on a LCD monitor. Each image displayed for 10 seconds, followed by 5 seconds for the observer to estimate the patient's age. A SMI RED250 eye movement monitoring system recorded the observer's eye position, and fixation time.
Results
Data on four rhytidectomy patient images showed decreased fixation time on some features of aging post rejuvenation. Post rhytidectomy, the average fixation time on the neck decreased by 115.25„b32.8 ms. In a patient post blepharoplasty with rhytidectomy, the average fixation of the left and right under eye circles decreased from 424 ms to 120.2 ms, and 252.6 to 100.1 ms postoperatively. The observers scan path varied between pre and postoperative images, but the central triangle pattern remained predominant both pre and postoperatively.
Conclusions: Eye tracking provides some quantitative data post facial rejuvenation. Future studies using this technology can further enhance our understanding of visual attention with aesthetic outcomes.
