Resolution of papilledema associated with OSA treatment.

Obstructive sleep apnea (OSA) is a common disorder and is associated with brain functional and morphological alterations. The association between OSA and papilledema, however, is not well known. We describe a 53-year-old morbidly obese female who presented with impaired vision due to bilateral papilledema. Polysomnography revealed severe OSA. She was treated with continuous positive airway pressure, and within a few weeks her papilledema and vision improved. This case report is consistent with association of OSA with papilledema but does not prove causality.
