2018 AANS Annual Scientific Meeting-716. Optic Nerve Diffusion Tensor Abnormality in Children Presenting Acutely with Hydrocephalus

716. Optic Nerve Diffusion Tensor Abnormality in Children Presenting Acutely with Hydrocephalus

Video Transcription

Video Summary

Jennifer Kwon, a neurosurgery resident at Stanford University, discussed optic nerve diffusion tensor imaging abnormalities in children with hydrocephalus in a video presentation. Kwon explained that hydrocephalus can cause visual changes and long-lasting deficits, and visualizing optic nerve swelling and compression on standard MR imaging is possible. However, no studies have examined DTI-based microstructural changes in the optic nerves of children with hydrocephalus. Kwon and her team conducted a study with 21 children with acute hydrocephalus and found that preoperative values of mean diffusivity (MD) and fractional anisotropy (FA) significantly differed from healthy controls. However, after surgical intervention, the optic nerve values improved but did not fully normalize. These findings suggest a potential role for optic nerve DTI in assessing surgical success and permanent neurologic deficits. No credits were provided for the video.
