A quantitative assessment of eye alignment in cats after corpus callosum transection.

Eye alignment was measured in cats using a technique involving projection of retinal landmarks, determination of receptive field separation in binocular units and measurement of ganglion cell density. This technique has an accuracy of 20' of arc. Using this technique, we determined that alterations in eye alignment occur following surgical transection of the corpus callosum in cats. These changes are first observed two weeks after surgery and are still present ten months later.
