Table 3 represents tracking and convergence abilities for the subjects in the experimental and control group. Tracking was analyzed as either smooth, jerky or fixation loss. Convergence ability was measured as no convergence, inability to converge on a target within a 12 cm working distance and also convergence of less than a 12 cm working distance. The experimental group showed more difficulty with tracking and convergence.

Phoria measurements represent the balance between visual sensory and motor relationships which establish spatial perception. Esophoria describes the state of oculomotor balance causing the eyes to be pulled inwards (when fusion is lost) causing spatial perception of objects to be perceived closer. Exophoria is the state of oculomotor balance causing the eyes to be pulled outwards (when fusion is lost). This causes a spatial perception of objects to be perceived farther away. Orthophoria represents no latent deviation. Strabismus is the state of an actual ocular deviation.
