With the<unk> , you cannot differentiate between a manifest deviation or latent deviation. The white arrow on the white X-Axis measures for horizontal deviations in which, odd numbers represent eso deviations and even numbers represents exo deviations. The red arrow on the red Y-Axis measures for vertical deviations; odd numbers represent right hyper deviations and even numbers represents left hyper deviations. In the absence of a deviated eye, both red and white arrows point to zero, indicating that there is no deviation present. The presence of torsion is determined subjectively; the patient is instructed to take hold of the torsion lever and make it straight.
