Impact of Continuous Positive Airway Pressure Treatment on Retinal Vasculature
Overview
A seven-year study indicates that CPAP treatment for obstructive sleep apnea may have effects on retinal vascular health. Participants with severe OSA using CPAP showed less retinal arterial narrowing compared to untreated counterparts.
Background
Obstructive sleep apnea (OSA) is associated with significant cardiovascular and cerebrovascular risks. Continuous positive airway pressure (CPAP) is a common treatment, yet its long-term effects on vascular health, particularly in the retina, are not fully understood. This study explores the potential of retinal imaging as a biomarker for systemic vascular health in OSA patients treated with CPAP, framing the results as exploratory.
Data Highlights
| Measure | CPAP Users (Mean) | Non-CPAP Users (Mean) |
|---|---|---|
| CRAE | 161.0 | 143.2 |
| CRVE | 200.9 | 186.9 |
Key Findings
- Severe OSA patients on CPAP had a mean CRAE of 161.0 compared to 143.2 in non-CPAP users.
- Mean CRVE was 200.9 in CPAP users versus 186.9 in non-CPAP users.
- Longitudinal data suggested slower retinal vascular narrowing among CPAP users.
- Superotemporal RNFL was thicker in CPAP-treated patients than in untreated counterparts.
- Hypertension was more common among non-CPAP users, and stroke occurred only in this group.
Clinical Implications
The findings suggest that CPAP may have a protective effect on retinal vascular health in patients with severe OSA. Clinicians may consider monitoring retinal health as part of the management of OSA.
Conclusion
This study highlights the importance of retinal imaging in assessing systemic vascular health in severe OSA.
