And Now for some news ….
Eye Tracking and Concussions
Disconjugate eye movements have been associated with traumatic brain injury since ancient times. Ocular motility dysfunction may be present in up to 90% of patients with concussion or blast injury.
The authors of a recent study published in the Journal of Neurotrauma, developed an algorithm for eye tracking in which the Cartesian coordinates of the right and left pupils are tracked over 200 seconds and compared to each other as a subject watches a short film clip moving inside an aperture on a computer screen.
The authors prospectively eye tracked 64 normal healthy noninjured control subjects and compared findings to 75 trauma subjects with either a positive head CT (n=13), negative head CT (n=39) or non-head injury (n=23) to determine whether eye tracking would reveal the disconjugate gaze associated with both structural brain injury and concussion.
Tracking metrics were then correlated to the clinical concussion measure SCAT3 in trauma patients.
The study concluded that eye tracking may help quantify the severity of ocular motility disruption associated with concussion and structural brain injury.

Surgical vs Non-Surgical Treatment of Spinal Stenosis
A recent study from the Spine Patient Outcomes Research Trial (SPORT), looked 289 symptomatic lumbar spinal stenosis patients who were randomly assigned to either surgical or nonsurgical treatment.
This current study reviewed the results at 8 years post-treatment that were recently published showed some groups of patients with symptomatic lumbar spinal stenosis who opted for conservative care tended to do as well at long-term follow-up as patients who underwent surgery.
The study concluded that Patients with symptomatic spinal stenosis show diminishing benefits of surgery in as-treated analyses of the randomized group between 4 and 8 years, whereas outcomes in the observational group remained stable.
Loss to follow-up of patients with worse early outcomes in both treatment groups could lead to overestimates of long-term outcomes but likely not bias treatment effect estimates.
