- W4308592393 abstract "PurposeTo develop and validate a platform that can extract eye gaze metrics from surgeons observing cataract and vitreoretinal procedures, and to enable post-hoc data analysis to assess potential discrepancies in eye movement behavior according to surgeon experience.DesignExperimental, prospective, single-center study.ParticipantsEleven (11) ophthalmic surgeons observing deidentified vitreoretinal and cataract surgical procedures performed at a single university-based medical center.MethodsAn open-source platform was developed to extract gaze coordinates and metrics from ophthalmic surgeons via a computer vision algorithm in conjunction with a neural network to track and segment instruments and tissues, identifying areas of attention in the visual field of study subjects. Eleven surgeons provided validation data by watching videos of six heterogeneous vitreoretinal and cataract surgical phases.Main Outcome MeasuresAccuracy and distance traveled by the eye gaze of participants and overlap of the participants’ eye gaze with instruments and tissues while observing surgical procedures.ResultsThe platform demonstrated repeatability of >94% when acquiring the eye gaze behavior of subjects. Attending ophthalmic surgeons and clinical fellows exhibited a lower overall cartesian distance traveled in comparison to resident physicians in ophthalmology (P < 0.02). Ophthalmology residents and clinical fellows exhibited more fixations to the display area where surgical device parameters were superimposed compared to attending surgeons (P <0.05). There was a trend toward gaze overlap with the instrument tooltip location among resident physicians in comparison to attending surgeons and fellows (41.42% vs 34.8%, P > 0.2). The number and duration of fixations did not vary substantially among groups (P > 0.3).ConclusionsThe platform proved effective in extracting gaze metrics of ophthalmic surgeons. These preliminary data suggest that surgeon gaze behavior differs according to experience." @default.
