RETINAL BLOOD VESSEL TORTUOSITY AND SLEEP APNEA

This study in Clinical Ophthalmology described the relationship between retinal vascular tortuosity and obstructive sleep apnea (osa).   It concludes:

 Patients with OSA have increased retinal vascular tortuosity as compared to matched controls. Increased tortuosity of the retinal vasculature may be a novel association with OSA. A larger prospective study will be necessary to further explore this relationship and its clinical significance.
