Objective:

To investigate the effects of high-pillow sleeping posture on intraocular pressure (IOP) in patients with glaucoma.

Approach:

Key Findings:

• 66.7% of patients experienced increased IOP when transitioning to a high-pillow position.
• Mean IOP was higher in the high-pillow position (17.42 ± 4.34 mmHg) compared to supine (16.62 ± 3.81 mmHg).
• Lower ocular perfusion pressure (54.57 ± 8.19 mmHg) was observed in the high-pillow position.
• Greater 24-hour IOP variability was associated with the high-pillow posture.

Interpretation:

High-pillow sleeping posture is linked to elevated IOP and reduced ocular perfusion pressure in glaucoma patients, indicating potential risks for disease progression.

Limitations:

• Variability in head elevation angle was not recorded.
• Jugular vein assessments were conducted in healthy volunteers, not glaucoma patients.
• Limited subgroup sample sizes and wide dispersion in postural IOP values.

Conclusion:

The study suggests that high-pillow sleeping may adversely affect IOP in glaucoma patients, warranting further investigation.
