与最新的国际干眼指南[16]相比,我国的干眼专家共识更多的强调泪膜的不稳定和眼表的损伤,而TFOS Dry Eye Workshop II 2017(TFOS DEWS II 2017)[5]更关注与泪膜渗透压、眼表炎症及神经功能异常。DEWII[12]首次提出眼表组织未受到损伤、睑板腺未发现异常以及BUT、Schirmer I试验、角膜荧光素染色阴性,仅有眼部干涩、疲劳等不适症状经过休息或改善环境后症状消失定义为干眼临床前期。我国干眼诊疗建议专家组[17]建议定义为功能异常性干眼,其机制为眼表感觉神经阈值降低,刺激敏感,但早期没有器质性改变。患者可以通过改变不良生活习惯和工作习惯以及早期干预治疗得到缓解。
