FIGURE 6.

Eye alignment at age 1 year measured during automated, single-cover testing at 5 cardinal gaze positions. Control monkey AY and 3-wk monkey SY had small heterophorias. 12-wk monkey GO was esotropic, shown here when fixating with the right eye. This animal often displayed a right-eye dissociated horizontal deviation (DHD) as shown when fixating with the left eye. The dissociated vertical deviation (DVD) in the right eye is smaller than that in the left eye. 24-wk monkey HA had both a larger esotropia and larger DVDs. Mean ± SD (range indicated by shading).
