Abstract
- It is assumed that in esotropic cats the behavioural suppression of the nasal field reflects inhibition of the input conveyed through the temporal retinal afferents of the strabismic eye. We hypothesized that inhibition underlying the field defect might be actively operated by interocular competitive mechanisms. If so, effectiveness of the strabismic eye input might be restored and loss of the corresponding visual field might be recovered by interrupting the direct interactions between the eyes with the section of the optic chiasm. Results obtained in eight esotropic split-chiasm cats confirm the hypothesis and suggest that suppressive mechanisms of binocular rivarly are involved in the behavioral loss of the esotropic nasal field.
