睡着时抬高头部会提高青光眼病人的眼部压力,可能会加剧神经损伤。 Elevating head while sleeping raises eye pressure in glaucoma patients, possibly worsening nerve damage.

对144名青光眼患者进行的一项研究发现,使用两个枕头与头顶睡在一起会增加眼部压力,平均增加1.61毫米汞,而平铺躺着时则可能加剧眼神经损伤。 A study of 144 people with glaucoma finds that sleeping with the head elevated using two pillows increases eye pressure by an average of 1.61 mm Hg compared to lying flat, potentially worsening optic nerve damage. 研究者将这种上升与颈部弹性压缩颈部血管、减少血液流动和从眼睛流出液体联系起来。 Researchers link this rise to neck flexion compressing the jugular vein, reducing blood flow and fluid drainage from the eye. 对20名健康志愿者的超声波扫描显示,当头部抬起时,颈血管缩小。 Ultrasound scans on 20 healthy volunteers showed narrowed jugular veins when the head was raised. 调查结果表明,在没有枕头的情况下睡觉,或只使用一个薄枕头,可能有助于控制内心压力,不过还需要进一步研究,以确认好处。 The findings suggest sleeping without pillows or using just one thin pillow may help manage intraocular pressure, though further research is needed to confirm benefits.
