M. Cogdal Psychogenic flutter, also known as voluntary nystagmus, is a rare condition in which one can voluntarily induce rapid, horizontal eye movements resembling nystagmus, a condition typically associated with involuntary eye motion. Unlike true nystagmus, psychogenic flutter does not stem from neurological or vestibular dysfunction but is often consciously controlled and can be stopped at will. These rapid, oscillatory movements are usually brief and occur without associated symptoms like dizziness or vision impairment, but if done repeatedly some of these side effects can occur. While its exact cause is unknown, psychogenic flutter is often considered a benign condition and is not typically linked to any underlying medical issue. #voluntarynystagmus #pychogenicflutter #drkieutips #greenscreen
