Eye-CP Monitoring: Using Pupillometry and Optic Nerve Sheath Diameter for ICP Monitoring

Video Transcription

Video Summary

In this video, the speaker discusses the use of ocular biomarkers for monitoring intracranial pressure (ICP) and detecting brain injury. They highlight the limitations of clinical exams, such as anisocoria (difference in pupil size), which occurs in over 60% of neuroICU patients and may not always indicate emergent neurologic decline. The speaker introduces the use of non-invasive tools, such as fundoscopic exams and quantitative pupilometry, to better assess patients' need for imaging. They explain that pupilometry, using devices like the neurooptics pupilometer, provides measurements such as resting pupil size, constriction velocity, dilation velocity, and latency, which can be compiled into a neurologic pupil index. Abnormal values include an NPI below 3, a difference in NPI between both eyes of 0.7 or greater, and a difference in resting pupil size of 1 mm or greater. The speaker also discusses the measurement of optic nerve sheath diameter as an indicator of elevated ICP, with an optic nerve sheath diameter over 6 mm being a cause for concern. They mention ongoing research into other ocular biomarkers and their potential for assessing brain injury and prognosis.
