FIGURE 9

Stable fixation vs latent/manifest latent nystagmus in horizontal eye position tracings from 4 monkeys; fixating monocularly with the right eye (RE) or left eye (LE) covered, and viewing binocularly. A and B, Stable fixation in control monkey WE and 3-wk monkey TE. C, Latent nystagmus, manifest-latent nystagmus and right-eye dissociated horizontal deviation (DHD) in 12-wk monkey GO. D, Latent and manifest-latent nystagmus in 24-wk monkey HA. Nystagmus tended to be lower velocity in the fixating eye. Upward = rightward eye position.
