Compared with the supine position, the high-pillow position is associated with increased IOP and decreased OPP in patients with glaucoma, which may be linked to jugular venous compression. Patients with glaucoma may benefit from avoiding sleeping postures that induce jugular venous compression to mitigate postural IOP elevation, though further studies are needed to validate these preliminary associations.
Liu et al. (Tue,) studied this question.
