A recent study published in the British Journal of Ophthalmology has uncovered a potential link between sleeping with two pillows and increased internal eye pressure in individuals with glaucoma. This finding highlights a surprising factor that could influence eye health and disease progression.
Key Findings from the Research
The research involved monitoring glaucoma patients and found that eye pressure rose in over two-thirds (67 per cent) of participants when they slept on pillows compared to lying flat. This increase in pressure is significant as elevated intraocular pressure is a major risk factor for glaucoma, a condition that can lead to vision loss if not managed properly.
Mechanism Behind the Pressure Increase
Scientists believe the rise in eye pressure may be due to compression of the jugular vein, which is responsible for draining blood from the head back to the heart. Ultrasounds conducted on healthy volunteers confirmed that adopting a high-pillow position led to significant constriction of the jugular vein's lumen, potentially impeding blood flow and increasing pressure within the eye.
Implications for Glaucoma Patients
Experts suggest that individuals with glaucoma could benefit from avoiding sleeping postures that cause this compression. While the study provides valuable insights, researchers emphasise that further investigation is needed to fully understand the long-term effects and to develop specific recommendations for sleep habits in glaucoma management.
Broader Context and Recommendations
This study emerges during Glaucoma Awareness Month, underscoring the importance of early detection and proactive management of the condition. Patients are advised to consult with their healthcare providers about sleep positions and other lifestyle factors that might impact their eye health. Simple adjustments, such as modifying pillow use, could play a role in reducing risk and improving outcomes for those affected by glaucoma.
