A case of voluntary flutter—yes it’s just a party trick!! Video courtesy of @doughnerd future 👰 to fellow 👁 geek @gpark245. 🧠👁. . . Voluntary flutter aka voluntary “nystagmus” are self-induced saccadic oscillations characterized by high frequency bursts of conjugate oscillations—most commonly in the horizontal plane. This party trick may pose diagnostic challenges in patient presenting with symptoms as a result of the movements. Distinguishing features are: ✔️Unsustained oscillatory movements ✔️Induction by convergence ✔️Associations with facial grimacing or eyelid flutter Pathologic flutter and opsoclonus are more sustained. . . . #eye #oeil #oyo #olho #eyeclinic #flutter #voluntary #partytrick #ophthalmology #ophtalmologie #oftalmologia #oftalmología #neurology #neurologie #neurologia #neurología #neuroophtho #neuroophthalmology #theeyeshaveit
