A study from Zhejiang University indicates that sleeping with the head elevated on multiple pillows may worsen intraocular pressure (IOP) control in glaucoma patients. Among the 144 participants, sleeping in a high-pillow position led to an average IOP increase of 1.6 mm Hg and greater fluctuations in IOP over 24 hours, alongside reduced ocular perfusion pressure (OPP), which is crucial for ocular blood flow. The study suggests that neck flexion may impede venous drainage, raising concerns about long-term effects on glaucoma progression.
1. High-pillow sleeping increases IOP in glaucoma patients. 2. Average IOP rise: 1.6 mm Hg. 3. Neck flexion may impair venous drainage. 4. Greater 24-hour IOP fluctuations noted. 5. Reduced ocular perfusion pressure linked to glaucoma progression. 6. Study involved 144 glaucoma patients with continuous IOP monitoring. 7. Further longitudinal studies are needed for comprehensive understanding.
