Optically induced strabismus results in visual field losses in cats.
Kittens were reared using goggles containing a prism that simulated a convergent strabismus. A bilateral loss of 30 degrees of the contralateral monocular visual field resulted, indicating that the components of the visual pathways representing the nasal visual field are more sensitive to spatially conflicting visual inputs than the components representing the temporal field. Differences in the extent of binocular visual fields occurred, with alternating fixators demonstrating a full field and unilateral fixators demonstrating a binocular field reduction ipsilateral to the deviating eye.
