“…Universally, positive fusional vergence training has been shown to improve near vision symptoms resulting in enhanced positive fusional amplitude (Cooper et al, 1983;Brautaset & Jennings., 2006). No significant (p>0.05) phoria adaptation or reduction in the CA response between 5, 10 and 15 minutes of viewing showing no effect of duration.…”

“…The results of the above study are similar to that of Vaegan's (1979) except that the magnitude of improvement in vergence ability reported by Vaegan appears to be considerably smaller in BO values. A study on the effect of positive fusional vergence training on fusional vergence ability and asthenopia in patients with convergence insufficiency (CI) showed that upon completion of training all patients had reduced asthenopic symptoms with an increase in the BO fusional range (Cooper et al 1983). Also several other studies have reported an increase in the positive fusional vergence range following training (North and Henson., 1992;Dalziel, 1981;Brautaset & Jennings., 2006).…”

“…Prompt and accurate diagnosis and management of mTBI generally increases an individual's prognosis for neurological recovery [13][14][15] and safe return to duty [16][17][18]. Therefore, the accurate assessment of oculomotor functions is essential for providing an adequate treatment regimen, thereby ensuring that warfighters with mTBI achieve proper recovery of their oculomotor problems before returning to duty [10][11][19][20][21][22][23][24][25]. Premature return to duty places warfighters at greater risk of disability if they suffer additional concussive trauma [26].…”

“…Premature return to duty places warfighters at greater risk of disability if they suffer additional concussive trauma [26]. Fortunately, most oculomotor dysfunctions resulting from mTBI can be ameliorated with noninvasive rehabilitative intervention such as vision therapy (i.e., neurovisual rehabilitation) and/or such passive treatment such as a spectacle prescription with prismatic lenses or other optical devices [11,[20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36].…”

Abstract-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.

Objective: To compare vision therapy/orthoptics, pencil push-ups, and placebo vision therapy/orthoptics as treatments for symptomatic convergence insufficiency in children 9 to 18 years of age.Methods: In a randomized, multicenter clinical trial, 47 children 9 to 18 years of age with symptomatic convergence insufficiency were randomly assigned to receive 12 weeks of office-based vision therapy/orthoptics, officebased placebo vision therapy/orthoptics, or home-based pencil push-ups therapy. Main Outcome Measures:The primary outcome measure was the symptom score on the Convergence Insufficiency Symptom Survey. Secondary outcome measures were the near point of convergence and positive fusional vergence at near.Results: Symptoms, which were similar in all groups at baseline, were significantly reduced in the vision therapy/ orthoptics group (mean symptom score decreased from 32.1 to 9.5) but not in the pencil push-ups (mean symptom score decreased from 29.3 to 25.9) or placebo vision therapy/orthoptics groups (mean symptom score decreased from 30.7 to 24.2). Only patients in the vision therapy/orthoptics group demonstrated both statistically and clinically significant changes in the clinical measures of near point of convergence (from 13.7 cm to 4.5 cm; PϽ.001) and positive fusional vergence at near (from 12.5 prism diopters to 31.8 prism diopters; PϽ.001).Conclusions: In this pilot study, vision therapy/ orthoptics was more effective than pencil push-ups or placebo vision therapy/orthoptics in reducing symptoms and improving signs of convergence insufficiency in children 9 to 18 years of age. Neither pencil push-ups nor placebo vision therapy/orthoptics was effective in improving either symptoms or signs associated with convergence insufficiency.
