Clinical test responses to different orthoptic exercise regimes in typical young adults.
Bottom Line: Accommodation measures were prone to large instruction/effort effects and monocular accommodation facility was subject to large practice effects.Separating convergence and accommodation exercises seemed more effective than exercising both systems concurrently and suggests that stimulation of accommodation and convergence may act in an additive fashion to aid responses.Instruction/effort effects are large and should be carefully controlled if claims for the efficacy of any exercise regime are to be made.

Mentions: All exercise groups except the Both group improved their near and distance BO fusion ranges somewhat to both diplopia and recovery (Figure3) (main effects at least F1,148 > 10.25, p < 0.002 in all cases, with significant group vs change interactions (p < 0.05) in all except the distance recovery point (which was marginal p < 0.1). The Nil and Motion groups did not improve significantly.
