Subject Idiopathic Ocular Flutter
History This little boy complained of difficulty focusing. On examination he was found to have ocular flutter. He was otherwise neurologically intact and in good general health. Investigations were directed to rule out 1. Neuroblastoma (see ID 936-8) 2. Enterovirus infection 3. Parainfectious process (See ID166-6) 4. Multiple sclerosis (See ID166-2) 5. Meningitis 6. Accidental drug toxicity - All studies were negative. A full diagnostic work up ruled out a neuroblastoma. A spinal tap showed normal cerebrospinal fluid. Differential diagnosis considered was: 1. Convergence-initiated voluntary flutter and 2. Idiopathic ocular flutter In 1954 Cogan first used the term "ocular flutter" to describe a rare disorder of horizontal eye movements characterized by rapid bursts of synchronous back-to-back horizontal oscillatory movements usually seen in the primary position of gaze. Since then, there have been over 50 reports, usually single cases or small series, linking the phenomenon to a wide variety of brainstem and cerebellar conditions, e.g. post enteroviral infection, cerebral malaria, cyclosporine treatment and meningitis, but perhaps most frequently associated with parainfectious states or, with opsoclonus, as a paraneoplastic manifestation of occult malignancy. Convergence-initiated voluntary flutter is a normal intrinsic capability in man and is often accompanied by facial grimacing or eyelid flutter. Voluntary flutter is usually not well sustained in contrast to pathologic flutter which is more sustained irrespective of the patient's vergence state. Idiopathic ocular flutter should only be diagnosed when all other potential etiologies have been ruled out by appropriate investigations.
