Abstract
We describe a patient with convergence-retraction nystagmus caused by a hemorrhage in the right thalamus and dorsal midbrain. This was docum ented by magnetic resonance imaging. Convergence-retraction nystagmus has a high localizing value for a (most frequently tumorous or vascula r) lesion near of within the dorsal midbrain. The convergent eye movem ents have the characteristics of saccades; the retraction nystagmus is caused by simultaneous contraction of all extraocular muscles.
