Anticholinergic therapy
Medications such as trihexyphenidyl may be prescribed to reduce the frequency and amplitude of square-wave jerks by modulating abnormal cerebellar-eye movement connections.
Additional treatment options
Vision therapy and oculomotor training
Specialized eye exercises and visual rehabilitation techniques can help improve gaze stability and reduce the impact of involuntary eye movements on daily activities.
