Do you ever attribute oscillopsia to a cortical lesion?

"Oscillopsia may be defined as an optic illusory movement of a viewed stationary object." (Bender, 1965)

The overwhelmingly most common causes are 1) an abnormal vestibular-ocular reflex (VOR) due to peripheral or central vestibulopathy or extraocular muscle paresis and 2) nystagmus (Caveat: patients with congenital nystagmus may not report oscillopsia - central adaptation?).

I have never encountered oscillopsia of cortical origin. In his series of 13 patients with oscillopsia, Bender, PMID 14315673 reported one patient with a cortical lesion (right occipital) and "constant shimmering" at the edges of scotomas in his left visual field. No nystagmus was observed.
