Comparative clinical studies on foveal and peripheral optokinetic nystagmus

Comparative examinations made on patients suffering of a degenerative disease of the retina causing a loss of their macular or their peripheral vision respectively and on patients with a lesion of the frontal or occipital lobe have revealed that the optokinetic nystagmus of patients with a frontal lesion behaves similar to the one elicited in patients with macular pathology, whereas the optokinetic nystagmus of patients with a lesion of the occipital eye fields revealed similar characteristics as the one evoked in patients with tubular field.
