Strabismus Measurements in the Siamese Cat

Anatomical and neurophysiological studies suggest a relationship between "abnormal" visual pathways and strabismus found in the Siamese cat. A telephotographic method for measuring eye positions in these cats reveals that newborn Siamese cats have a conspicuous exotropia appearance. Adult animals appear to have esotropia, orthophoria, or exotropia, which can be intermittent.
