Pelizaeus-Merzbacher disease (PMD) is a progressive, degenerative chromosomal disorder of the central nervous system (CNS) caused by defective myelin production. PMD is a variant of leukodystrophy, which is characterized by neuromuscular dysfunctions of the CNS. Thus, the clinical symptoms of PMD arise from widespread hypomyelination of the nervous system and include developmental motor disability, ataxia, choreoathetosis, and cognitive impairment. In addition, an anesthesiologist must consider the possibility of abnormal muscle tone, such as spasticity, airway complications due to pharyngeal muscle weakness, and the risks of aspiration and seizure.Only a few case reports have been published on the anesthetic management of patients with PMD because of its low prevalence [1], which is about 0.13 or 1.45 per 100,000 live births [2,3]. Here we present the case of a 13-year-old girl with PMD who underwent elective ophthalmic surgery under general anesthesia.
CASE REPORTA 13-year-old girl required general anesthesia for resection and recession of ocular muscles because of intermittent exotropia. Her mental development was delayed by about five years, and she exhibited snoring while sleeping and mild ataxia. She had been diagnosed with PMD by genetic testing at eight years and had been followed twice per annum at a descriptor hospital. However, she had not been medicated for PMD and experienced hypotonia, spasticity, dystonic posturing, and seizures. She had no history of epilepsy, aspi-
