Retinal Vascular Network and Obstructive Sleep Apnea
- Conditions
- Obstructive Sleep Apnea Syndrome
- Interventions
- Other: complete ophthalmological examination
- Registration Number
- NCT03979001
- Lead Sponsor
- Centre Hospitalier Universitaire Dijon
- Brief Summary
Obstructive sleep apnea syndrome (OSA) is thought to lead to systemic vascular lesions that may be preceded by early microvascular lesions in the eyes and in particular in the retina. The improvement of ophthalmological imaging techniques by OCTangiography allows a precise non-invasive study of the retinal microvascular network. This new rapid and non-invasive retinal imaging tool could reveal micro-vascular lesions related to OSA. To the investigator's knowledge, this would be the first OCT-angiography description of a cohort of patients with OSA. If these results are confirmed, it would be interesting to study the correlation between these micro-vascular lesions and the cardiovascular risk of his patients.
