The paper analyzes the diagnostic capacities of two studies (the routine Schirmer test and lacrimal meniscus biometry). It indicates the basic limitations of the Schirmer test and describes a procedure for lacrimal meniscus biometry. Based on the results of studying the lacrimal meniscus in healthy individuals from a control group, the authors revealed a relationship of the height of the lacrimal meniscus to the area and horizontal size of the palpebral fissure. Comparison of the results of studies of basal lacrimal secretion in the presence of dry keratoconjunctivitis and dry eye syndrome in the study patients with hypolacrimation defined the latter as mild, moderate, and severe. There was discordance between the values in 33.85% of cases. The Schirmer test has not shown to be the method of choice in examining basal lacrimal production; erroneous results may be obtained in a third of patients. Lacrimal meniscus biometry makes it possible to identify the degree of significant hypolacrimation more exactly and to minimize the indices of preserved basal secretion.
该论文分析了两项研究（常规泪液分泌试验和泪液弯月面生物测量）的诊断能力。它指出了泪液分泌试验的基本局限性，并描述了泪液弯月面生物测量的程序。基于对对照组健康个体泪液弯月面的研究结果，作者揭示了泪液弯月面高度与睑裂面积和水平大小之间的关系。对研究患者中存在干燥性角结膜炎和干眼综合征且泪液分泌减少时基础泪液分泌研究结果的比较，将后者定义为轻度、中度和重度。在33.85%的病例中，各项数值之间存在不一致。泪液分泌试验并未被证明是检查基础泪液分泌的首选方法；三分之一的患者可能会得到错误结果。泪液弯月面生物测量能够更准确地识别显著泪液分泌减少的程度，并将基础分泌保留指标降至最低。
