睑板腺功能障碍相关干眼的临床检查进展

摘要

Dry eye is one of the most commonly encountered problems in ophthalmology .Both aqueous tear deficiency and increasing evaporation lead to dry eye .It has been recognized that meibomian gland dysfunction plays an important role in the causes of dry eye .To make a diagnosis of dry eye which is mainly caused by meibomian gland dysfunction ,the doctors should learn about the symptoms ,signs and clinical examinations of the patients .There are a variety of clinical examinations in the diagnosis of dry eye.Current clinical examinations of diagnosis include Schirmer test ,tear break-up time and so on. Emerging technologies include OCULUS Keratograph ,interferometry,tear osmolarity and so on.It′s expected to find a readily available,reproducible and objective diagnostic test for dry eye .%干眼是临床上常见的眼科疾病之一，包括泪液分泌不足引起的干眼和泪液蒸发过强引起的干眼。其中后者主要指睑板腺功能障碍引起的干眼。目前关于睑板腺功能障碍性干眼的诊断尚无统一标准，临床上主要依靠症状、体征以及相应辅助检查。目前干眼的临床检查种类繁多，传统的方法如Schirmer试验、泪膜破裂时间等，新兴的临床检查方法如眼表综合分析仪、干眼仪、泪液渗透压等。期待能够找到简便、可重复性高、较为客观的检查方法来辅助诊断干眼。
