Corneal touch thresholds (CTT) were measured in 30 non-pregnant women serving as a control group and 29 pregnant women at different times during and after pregnancy. The results show that CTT becomes significantly higher after 31 weeks of pregnancy. However, only 86% of the subjects showed a difference in CTT during and after pregnancy, while 52% reported having some swelling. The loss of sensitivity (CTT-1) is assumed to be related to the water retention occurring during pregnancy, a view which is supported by some measurements of corneal thickness. It is suggested that this study may have exposed a new, hitherto unknown, way of monitoring pregnant women.
在30名未怀孕女性组成的对照组以及29名处于孕期不同阶段及产后的孕妇中测量了角膜触觉阈值(CTT)。结果显示,怀孕31周后CTT显著升高。然而,只有86%的受试者在孕期和产后CTT有差异,而52%的受试者报告有一些肿胀。敏感度丧失(CTT-1)被认为与孕期发生的水分潴留有关,角膜厚度的一些测量结果支持了这一观点。有人认为,这项研究可能揭示了一种监测孕妇的全新且此前未知的方法。
