Ophthalmologist Kaweh Mansouri has advocated for incorporating sleep evaluations into standard glaucoma management. Recent evidence suggests that nocturnal changes in body position and ocular pressure during sleep cycles could influence disease progression.
Why it matters
Understanding how nighttime physiological processes affect the eye is critical because translaminar vascular stresses occurring while sleeping may negatively impact the optic nerve. Integrating sleep health into clinical care could offer a more comprehensive approach to managing glaucoma.
A 2026 study of 144 patients found that high pillow positioning during sleep increases intraocular pressure and decreases ocular perfusion pressure. Intraocular pressure in most glaucoma patients typically peaks between 3 a.m. and 4 a.m.

The details
Nocturnal transitions in intraocular pressure, blood pressure, and respiration contribute to vascular stresses on the optic nerve. Researchers have noted that while aqueous humor production decreases by half during sleep, other factors such as head elevation and pillow pressure significantly alter ocular health metrics.
Timeline
Intraocular pressure in glaucoma patients peaks between 3 a.m. and 4 a.m.
A study regarding patient sleep positions was conducted in 2026.
Health Landscape
This research builds upon the 2026 study by Liu and colleagues to further define how nocturnal habits influence chronic eye conditions. By connecting sleep mechanics to ocular health, this work shifts clinical focus toward managing a patient's full 24-hour cycle rather than just daytime metrics.
Patients may benefit from discussing their sleeping habits and pillow elevation with their ophthalmologist to better manage intraocular pressure. Simple adjustments, such as maintaining a specific head elevation angle, may help mitigate the nocturnal stresses placed on the optic nerve.
The takeaway
Since humans spend one-third of their lives sleeping, clinicians increasingly view the nocturnal period as a vital time for monitoring eye health. Patients should consider the impact of their sleep environment on their overall ocular stability when consulting with their medical providers.
