5 Key Takeaways

• 1

  Two-thirds of glaucoma patients showed increased intraocular pressure (IOP) when sleeping with their head elevated on two pillows.

• 2

  The high-pillow position resulted in a mean IOP increase of 1.61 mmHg compared to the supine position.

• 3

  Ocular perfusion pressure (OPP) was significantly lower in the high-pillow position than in the supine position.

• 4

  Younger patients and those with primary open-angle glaucoma experienced larger IOP fluctuations in the high-pillow position.

• 5

  The study highlights the need for further research due to limitations such as variability in head elevation and small sample sizes.
