The prevalence of oculomotor dysfunctions associated with blast-induced mild
traumatic brain injury (mTBI) in warfighters has increased as a consequence of
recent conflicts. This study evaluated the effectiveness of computerized
oculomotor vision screening (COVS) in a military population. Oculomotor functions
were assessed with COVS and by conventional methods in 20 U.S. military personnel
with and 20 without mTBI.
The validity of COVS was determined by Pearson
correlation and Bland-Altman method or the kappa coefficient. The repeatability
of the COVS was assessed with the coefficient of repeatability or the kappa
coefficient. The results showed that COVS had high sensitivity and specificity
for screening near oculomotor functions. Overall, the COVS showed excellent
validity and repeatability for assessing near lateral and vertical phorias, Worth
4 Dot, and fixation, as well as pursuit and saccadic eye movements. Despite the
strong Pearson correlation, the Bland-Altman analysis identified minor to
moderate discrepancies for both positive and negative fusional vergence and their
associated recovery as well as for the monocular accommodative facility measurements. This study demonstrated that non-eye-care professionals may be able
to use the COVS as a tool to efficiently screen oculomotor functions in a military population with or without mTBI.
