We investigated the benefits of a new test on the lacrimal system for Dry Eye. This additional test to facilitate the diagnosis of dry eye is described and compared with the Schirmer test and with the results of a patient questionnaire. This simple test uses materials available in all optometric practices. An assistant with brief training can administer the test for the optometrist. The patient's monocular distance visual acuity was measured. One drop of Celluvisc was instilled into each eye; a stop watch recorded the time necessary for the patient to regain the predropped visual acuity. Each patient received a standard Schirmer test and answered a questionnaire. Preliminary results from this new test suggest a correlation between a dry eye with patient symptoms and the length of time for return to normal visual acuity after the use of one drop of Celluvisc. Further investigations should be conducted with a larger population using a precise eye drop dispenser. With this new test, a practitioner would have another method to diagnose a dry eye.
我们研究了一种针对干眼症泪腺系统的新测试的益处。本文描述了这种有助于干眼症诊断的附加测试，并将其与泪液分泌试验以及患者问卷结果进行了比较。这种简单测试使用的材料在所有验光诊所都有。经过简短培训的助手即可为验光师进行此项测试。测量患者的单眼远视力。每只眼睛滴入一滴羧甲基纤维素钠滴眼液；用秒表记录患者恢复滴药前视力所需的时间。每位患者都接受了标准的泪液分泌试验并回答了一份问卷。这项新测试的初步结果表明，干眼症与患者症状之间存在关联，且与使用一滴羧甲基纤维素钠滴眼液后恢复正常视力的时间长短有关。应使用精确的滴眼液分配器，对更多人群进行进一步研究。有了这项新测试，从业者将拥有另一种诊断干眼症的方法。
