To save lives and eyes, ODs are teaching students and residents to query their patients about total sleep time and total sleep quality while looking for characteristic facial features such as floppy eyelids and wide neck, reports Optometry Times.

OSAS approximately doubles the risk of most ocular-vascular diseases, including low-tension glaucoma, and is extremely common in non-arteritic ischemic optic neuropathy (NAION).

This is especially true for patients with a low ocular perfusion pressure below 50 mm Hg, estimated by subtracting their IOP from their diastolic blood pressure. It plays a role in central serous retinopathy, central retinal vein occlusion, and notably increases the risk of NAION by a factor of six times.5
