摘要
目的通过测量原发性开角型青光眼(POAG)患者在不同体位下的眼压,研究眼压变化和睡眠体位的关系,探索POAG双眼不对称发病的机制。方法 109例确诊为POAG的患者被纳入研究,通过问卷调查了解患者睡眠体位倾向。经杯盘比(C/D)和视野缺损比较确立双眼不对称性。使用iCare手持回弹式眼压计测量不同体位状态的眼压值。对比双眼中较好眼和较差眼在不同体位下的眼压差异,观测侧卧位时低位眼和高位眼的眼压变化,分析双眼不对称性青光眼的发生是否与患者特定的睡眠倾向有关。结果 POAG患者以右侧卧位为主。在体位眼压测量中,右眼眼压由高到低依次为:右侧卧位>左侧卧位>平卧>坐位;左眼眼压由高到低依次为:左侧卧位>右侧卧位>平卧>坐位。POAG患者右侧卧位时,右眼眼压升高(7.15±4.52) mmHg(1 mmHg=0.133 kPa),左眼升高(5.97±4.20) mmHg(P=0.013),左侧卧位时左眼眼压升高(6.97±5.05) mmHg,右眼升高(5.50±5.04) mmHg(P=0.006)。在双眼不对称的31例POAG患者中,有特定侧位睡眠倾向的患者共25例,其中19例(76.0%)低位眼是病情较严重一侧眼;在此类患者群中,睡眠倾向与低位眼眼压升高有关(χ~2=7.675,P=0.041,Pearson列联系数为0.45)。结论 POAG患者侧卧位时低位眼眼压较高,长期固定侧位睡眠习惯可能导致低位眼发病较重,提示睡眠倾向可能是引起POAG不对称发病的原因之一。
