5 Key Takeaways

• 1

  A seven-year study suggests retinal imaging may reveal long-term vascular effects of CPAP treatment in obstructive sleep apnea (OSA).

• 2

  Participants with severe untreated OSA showed progressive retinal arterial narrowing, while CPAP appeared to attenuate this change.

• 3

  At seven years, CPAP-treated patients had a mean central retinal artery equivalent (CRAE) of 161.0 compared to 143.2 in untreated patients.

• 4

  The study found that retinal nerve fiber layer (RNFL) was thicker in severe OSA patients using CPAP than in untreated counterparts.

• 5

  The study's limitations include a small sample size and loss of participants, leading authors to frame results as exploratory.
