Improvement in ocular myasthenia gravis during CPAP therapy for sleep apnea.

We describe the case of a 73-year-old male with a history of ocular myasthenia gravis (OMG) who was followed through diagnosis and treatment of sleep-disordered breathing (SDB). Therapeutic use of continuous positive airway pressure (CPAP) led to improvement of not only SDB but also OMG. To our knowledge, this is the first paper describing this treatment benefit. This case report emphasizes the need to obtain a sleep history in patients with ocular myasthenia gravis in order to screen for SDB.
