In most cases, syringomyelia improves on its own after surgery to correct a Chiari malformation because the normal flow of cerebrospinal fluid is restored. Other symptoms may include poor balance, dizziness, diplopia (double vision), and repetitive downward eye movements ('downbeat nystagmus'). Chiari malformation type I is usually not associated with other neurological abnormalities, although it can cause neurological symptoms due to compression of the brainstem and spinal cord. 3.
