摘要
Obesity hypoventilation syndrome （OHS） is defined as obesity （body mass index, 〉30 kg/m^2） with daytime hypoventilation （PCO2, 〉45 mmHg） that is not secondary to cardiopulmonary or neurologic disease. Around 80-90% of the patients with OHS have obstructive sleep apnea and severe arterial oxygen desaturation. Obstructive sleep apnea has been found to be associated with a variety of eye diseases, including floppy eyelid syndrome, glaucoma, papilledema, nonarteritic anterior ischemic optic neuropathy, and retinal vein occlusion （RVO）. While the association between OHS and ophthalmologic disorders is not well-known, our case report sheds light on this association.
