Psychogenic convergence spasm mimicking ocular myasthenia.
A 14-year-old girl presented with a two-years history of fluctuating convergent strabismus, diplopia, and reading difficulty. She has been previously diagnosed by experienced neurologists as having ocular myasthenia and she had been treated for two years with anticholinesterase inhibitors and immunomodulatory drugs. After a thorough medical interview and neurological examination, a diagnosis of psychogenic convergence spasm was made. The patient was then reassured and the symptoms immediately disappeared. She also had psychotherapy and maintained a condition of sustained freedom from symptoms.
