A case of convergence evoked eyelid nystagmus.
The clinical and radiological features of a patient with convergence evoked, upward beating eyelid nystagmus, which occurred independently of ocular upbeating nystagmus, are presented. The eyelid nystagmus resulted from a large angiomatous lesion distorting the blood supply to the pontomesencephalic and pontomedullary junctions.
