Nystagmus; Eyelid Nystagmus
Description
Lid nystagmus is a rhythmic eyelid movement commonly seen as an epiphenomenon of vertical nystagmus (typically upbeating, as in this case) due to a shared central pathway controlling elevation of the lid and supraduction. There can be isolated lid nystagmus if there is accompanying impairment of supraduction, eg with lesions of specific oculomotor subnuclei. Lid nystagmus can also be seen in medullary or cerebellar disorders and can variably enhanced or suppressed by convergence.
