Transorbital sonography (TOS) represents an innovative tool for neurological assessment. It has been validated that the presence or absence of eyelid edema does not compromise the accuracy of ultrasound-based pupillary function measurements.

The 2 methods of measurement exhibit good consistency, with the TOS method demonstrating superior stability in monitoring data.

This approach provides a more accurate means of assessing pupillary function in patients with traumatic brain injury (TBI) who have periorbital hematoma or facial swelling, particularly when opening the eyelid is challenging, thereby addressing a significant clinical nursing challenge.

A total of 140 patients with traumatic brain injury (TBI), meeting the inclusion and exclusion criteria, were selected from a tertiary hospital in Zhejiang Province between January 2022 and December 2023.
